Thank you Gazzuzz ... how about the O2 voltage readings in my live scan pictures above. are they normal?

You have 2 sensors, B1S1(AF sensor) and B1S2 (oxygen sensor) 1 is a regular oxygen sensor while the other is an AF sensor.
An oxygen sensor will typically generate up to about 0.9 volts when the fuel mixture is rich and there is little unburned oxygen in the exhaust. When the mixture is lean, the sensor output voltage will drop down to about 0.2 volts or less. When the air/fuel mixture is balanced or at the equilibrium point of about 14.7 to 1, the sensor will read around .45 volts.

As for the AF sensor its a bit tricky, to understand but you will get voltage readings between 2.4 - 4volts I would have to write several pages about the AF sensor but for now you can read up more on it here http://www.motor.com/article.asp?article_ID=977

Generaly your readings look fine.

@Gazzuzz the way u arranged ur car papers is really nice but i bet u if u drive in Edo State d police there must find a fault in those papers. I was in Edo State 3wks ago And was driving (a camry) when some police men sopped me. They asked for DL And my car papers which i gave to them. When they saw i had all they asked for, then one of them pointed at my license they the column written colour that its custom they wrote there instead of the vehicle colour. i explained to them that d color of a car can be changed at anytime perhaps that is why d FRSC pple put custom there but they refused hear. After delaying me for about 30mins And discovered i was not ready to drop money, they now allowed me to go.

Another experience wt Nasarawa State police today. I was driving wt my family dis morning when i notice my vehicle temperature getting unusually high. So i parked my car under Keffi bridge, came down, opened d hood, And noticed one of d wires connecting d fan lossed contact. After fixing it And closing d hood. A police van came wt 3 policemen inside blocking my car. They said i was not supposed to park under d bridge. I explained it was my car that developed a fault that made me stop but they still did not want to hear. They tried intimidating me And asked for money but i refused to give them. Then they took me to their station. When we got there, they collected my car keys, vehicle papers And DL. I was still not intimidated. I now requested to see their DPO. Then they started soft-pedalling. Luckily, d DPO heard us n came out. When i explained what happened he barked at them n ordered them to give all d items they took from me. Na so i take free today Oº°˚˚°º . I have lost confidence in d Nigerian police!

@ the bolded did you say family? Those guys must me really mean.


Edo, ondo, 9thmile/enugu, bayelsa, warri..... I've seen them all and I'm always a step ahead. A friend of mine (police) once told me the Problem with nigerian drivers is their inability to follow a case to a logical conclusion they are always in a hurry. Worst case scenario when I'm at a check point with a stubborn chap is to make a "prank" call to a friend who says give them the phone, does some introduction shouts a little, next thing I here is sorry sir yes sir sorry sir he didn't tell us sir we will release him sir and I'm off!! I always beat them at their own game But I always meticulously ensure my papers are intact.

TCD:
Thank you. I had an exhaust leak some months ago just under the engine when i was traveling through that useless Abia state which was fixed. as at now no visible leaks as far as I can tell. or can a microscopic leak cause a catalyst error code?

About the spacer device, if i decide to fix that does it have any disadvantages or adverse effect on my engine in the long run? Thank you

The catalyst is designed to keep air polution minimal, insalling a sapcer will fool the ecm to beliving the catalyst is working efficiently without throwing any codes. The are no adverse effects to your engine. If you have a leak before the catalyst it could throw a code.

I will do nothing. I pay comprehensive insurance. Insurance will pay.

TCD:
Hello Gazzuz, I'm back with this again. The CEL came back on few days ago but this time only the P0420 code was seen after scanning.

what do I do from here ? also hoe do I run a live scan to test my 02 sensors. when I do a live scan with my scanner it just shows fluctuations in voltage readings. how do I interprete this?

Your catalyst is bad, have it replaced or install a spacer [img]http://t2.gstatic.com/images?q=tbn:ANd9GcRoH3QGY0hnGQ-zZ5lkWcmJoR2HR42oN8Zgc63hSYChp3mca508SKFAi8dO[/img] and your problems will be solved.

P.s I hope you don't have an exhaust leak?

its v4, no recent work has been done on the car.... and pls am a novice in this field thus i cant comprehend to an extent the term s u r using.... thanks for ur advice thoo, waiting for more help

Please contact somone with a car diagnostic equipment to check your vehicle, I'm afraid I can't go any further.

Wike was high on green leafs.

Congrats you are first to comment!!

hello gurus, pls today I wantd to go out and the car refused to start though it was kicking... any help or remedy or wat u tink will be the cause will ne highly appreciated.... thamks and God bless you all

B4 the long thing check on the instrument cluster, if there's a redlight that should blink without the key and then when key is placed in the ignition it would be stedy then go off. If that red light is blinking while ur cranking, you have a bad key, or an immobilizer issue.

Check ALL fuses in the fuse compartment and replace all burnt fuses

Get a small hand held scanner and scan car for codes that could be causing the problem.

Is your car V6 or I4?

Does it crank unusually fast?

Any work done of recent?

I watched this video on YouTube and I had to ask myself if I I've shown this acts of kindness and if I can still perform these kind acts. Well, i'd leave this video for you to ponder about. Enjoy!

The video make sense.

mrperfect85:
I say a very good evening to all the car gurus in the house. Please a brother needs help on an auto related issue dts bugging him.

Background:
I drive an automatic transmission nissan maxima 2001 model.Recently ,precisely on the 11th of this month, I discoverd I ran short of tranny fluid while driviing due to a leakage in the pipe that carries the fluid to the radiator bt luckily I had only driven the car for abt 10mins and was still close to the house so I turned back and had a technician look at it. We discovered the point of leakage n addressed the issue by changing a clip and that was resloved and subsequently, 5litres of OANDO dextron II was used to top up.
Prior to that time, I had bn experiencing issues of stalling with the car and my tech said it was due to d faulty injector mouth. I reckon its the component that carries the throttle position sensor. Anyways, we fixed It and the issue of stalling stopped.

Note: The check carried out on the tranny guage was done because the car stalled midway during the drive as it used to do.

Challenge:
Immediately after the injector mouth was changed, I noticed a sudden change in the transmission of the car.
1. Frequent aggressive gear changes especially from gear 1 to 2.
2. Unsual jerks during gear change.
3. Annoying sounds during driving especially at the point of changing gears.

Please pardon the litany of stories I just reeled out. What do u advise I do immediately to rectify this issue. Thanks

You used the wrong transmission fluid type, the recommended fluid is Nissan Matic D ATF, but Dextron III/Mercon ATF or equivalent may also be used.

Please drain the oil its contaminated.

CityNG:
Let me try to break this down.

It's simply against the law here in the US (many tokunbos comes from the US) for any manufacturer to specify a brand of product to use in their cars.

So folks you can use any spark plug from any maker as long as it meets the specs of your engine.

Now based on input from forums , some engines respond better to certain plug brand.

It seems to be the week for half baked ideas, schemes and products on Nairaland.

Unionised:
Hello All,
I want your opinions and advice on how to go about the following issues on my RAV4 Toyota 2002 Model

1. Diagnostic tools cannot read Transmission data. This means whenever i scan for issues, the machines cannot read my tranmission. Could this be a gear problem or a brain box issue?

2. My full and head lights keep burning out within a month. What could be the cause? I have spent good money buying new bulbs to no avail.

3. My Dashboard lights keep going off. The hazard, gear, ac, radio indicators all keep going off and on. I do tap on the dashboard to bring them on. As if there is a disconnect somewhere.

4. My car uses more fuel when I'm on the express than when I'm within town. for example, when i drive 2 hours to Ibadan, the car guzzles more fuel than when I spend the same 2 hours in traffic within Lagos. Is that normal?

5. I hear some serious humming noise whenever I'm speeding on the expressway. My mechanic says its the HUB that needs change, but I also suspect my exhaust. What do you think?

6. I changed my four tyres last month, and since then its as if my shock absorbers are no longer working. Every time I hit a gallop, the effect is amplified. Could it be the tyre pressure or something is missing?

7. This morning, I noticed some oil stain/drops under my engine where I parked my car at the office. What can that mean.

8. I last serviced my car 60 days ago. Do I need to change oil filter when servicing next? How frequently should i service the engine?

9. I just changed my Brake pads. My mechanic says the BRASS type is best for my car. What do you think?

Thanks in advance for your helpful tips.

what works for me

1.from experience only high end diagnostic tools will read out data from your vehicle, find someone who uses launch or equipment
specifically designed to diagnose Toyota to solve this problem. https://images02.olx-st.com/ui/3/78/96/1399534240_642527296_1-nulllaunch-x431-i-v-master-diagnostic-tool-computer-scanner.jpg

2.Buy tokumbor its 400 a piece lasts for years.

3.you have a partial contact, get a smart sparky to find it.

4. If you solve problem 1, you will understand problem 4.

5.Rule out the Exhaust by going under the car and looking for dark patches along the exhaust this will indicate a leak, or go under have
someone start engine and listen for leaks.

OR you bought tires meant for OFF road they are very noisy. https://www.cartoq.com/wp-content/uploads/2012/09/tyre-choices-photo.jpg


6. you have excessive air pressure in your tyres

7.For this one roll up your sleeves go under the car if you don't know the name take a picture we will tell you what is leaking and what to do
about it.
8.what does your car manual say?

9. so much rubbish in the market, i really cant tell you what to buy, but enter any Toyota dealership, their pads are expensive but will last way longer than the after market type, while saving your rotors from damage.

good luck.

WHERES THE REST OF THE CAR?

gambus007:
Hello gurus in the house,am planning to get a good tokunbo car.i want to know which is better Honda accord 1999 model euro spec aka adiddas vs Toyota camary 1998 aka pencil lite?both will be l4 engine.interms of maintain please which one is ok to use?my office is 100km to and fro.actually like the honda to toyota.

I have owned both cars in the past, and I can tell you from "experience" the engine and parts of both cars are durable very durable,rear struts of the camry are a mess, as they always keep getting damaged, transmission problems are more common on the honda, fuel economy is slightly better on the camry, handling and acceleration is better on the honda, 2nd hand value is 2daful on the toyota. Overall its hard to decide cause they both have their good and bad sides. Good luck

pragmatistm:
People, my car did a surprising thing yesterday. It behaved as usual but suddenly selected properly and the car moved well.
This morning, it got worse. The engine RPM was going to 3000 but car speed still around 20km/h. The SES light came on and I scanned immediately. I obtained P0325 and P1777. I saw the code P0325 Possible causes as

- Faulty knock sensor
- Knock sensor circuit poor electrical connection
- Knock sensor harness is open or shorted
- Faulty Engine Control Module (ECM)

and the P1777 Possible causes as
- Step Motor harness is open or shorted
- Step Motor poor electrical connection
- Faulty Step Motor

Please what should be checked this time.

I see its under possible causes so ur safe.

pragmatistm:
- Faulty knock sensor
- Knock sensor circuit poor electrical connection
- Knock sensor harness is open or shorted
- Faulty Engine Control Module (ECM)

Stop ignoring the knock sensor issue, and I hope you have not fried ur ecm cause its boldy written faulty engine control module.

No long thing, let's just asume the engine knocked after overheating would we be having this story?

Please do not accep the car.

If you do please don't open thread on NL "problem with mitsubishi after replacing engine".

Godiskind:
Pls I appeal to us to tell our real experience in such a way that someone may be able to learn somthing from it.
@HarkinromardeY, Thats one of d problems being faced, police would always want to take advantage of someone's ignorance. But I am glad u did not end up sleeping in d plice station, though I guess u must have spent a bit. But did u eventually learn from d mechanic where d chassis nos is indicated? Did u learn something from that ur experience?
@GAZZUZZ, I like d way u presented ur xperienc in this issue. It's quite enlightening sir. Atleast thru it someone can learn that car that is not older than 5yrs doesnt need custom duty cert or vehic inspectn paper. Also one can know some of the paper d car owner shud hav, and d ones that need periodic renewal. But I want to ask d following:
1.If u buy a brand new car, after using it for more than 5yrs, are u then required to go for custom duty paper?
2. Tint permit, is it not renewable?

Please let me rephrase, for a car bought brand new from say dana motors or choscaris, since they clear their cars in bulk, you might not have individual custom duty certificate ready as at time of purchase, you will only be issues a cover note from the company stating that the vehicle has been cleared and certificate will be issued in when recived.

For the vehicle inspection, it is for cars older than 5years.

CityNG where r u?

Nurey a friend has that same mercredes, and he threw out the original engine and installed the C class engine 4cylinder, with harness and ecu, the new engine was cheaper to source and its fuel injected.

Its as reliable as relaible can get.

Now on to your topic

Is certainly a car to avoid, with consistent complaints of broken coolant reservoir, window water leaks, headlining damaged from manufacturing, sunroof motor and sliding issues, defective jet washers and brake rotors that get bad quicly I belive this car came out with problems from the drawing board, little wonder our mechanics in a bid to salvage the car from being scrapped fit toyota engines in them.

charlesadeoye:
@GAZZUZZ- I have tried that at almost every local auto part shop around me, I keep getting those ones that won't screw into the o2 pot, that's why I posted those pictures I saw from someone's modification here

You need to go old sch, part dealers into 504 505 kinda stuff.

Go to any spare part shop and ask for spark plug "adaptors" spacers, you can modify them a bit and they will function perfectly. They cost 1 or 2hundred naira.

Nice thread

I have several cars but my papers are consistent.

For cars got brand new I do not have custom duty certificates or vehicle inspection papers, because the law specifically states its for cars older than 5years, so this is my list

1. Recipt of the vehicle
2.Certificate of ownership
3.Insurance
4.Vehicle licence
5.Recipt of number plate
6.Police clearance
7.Vio or MOT papers
8.Tint permit
9.Photocopy of drivers licence
10.Custom duty certificate
11.Vehicle registration booklet
12. Other papers to make it plenty

Note the only papers you have to renew every year are, 3,4,and 7 others are constant.

All my papers are spiral bound and look like the pic below. Funny thing is I haven't shown any one my papers in about 2 years.

Bossforeva:
most times man, the tiny light i see around, looks more sharp than those expanding light.

Its just like choosing between a 504 and a 505 same thing.

bigsmoke2:
i drive a 99 camry, whenever i brake from high speed say like 100km/h i expirience this jerky feeling frm my brake pedal. Is this a cause for alarm or just my break pads wearing pls i need advice

Its either your abs pump malfunctioning

Faulty (uneven) rotors or brake disks. [img]http://t2.gstatic.com/images?q=tbn:ANd9GcSsgij0pTyQNPN41HnlWiamU3oedTp7OXDAt7f7vPT56YmTd8R65UPTXgMo[/img]

Readonee35L:
God!!!
what have you done??

why did you destroy the life of the humble car?
That car has a very reliable engine and tranny, i dont even know why you changed the engine in the first place(Excess Cash I Guess)....Even if there was a need to replace the engine why didnt you go for the exact type.... Now the car is messed up
my best advice ,return the engine you bought and add extra cash to the seller for your exact type of engine, and revert all does illegal wiring ...
my 10cents for you.

and if you still have enough cash to spend in the car you can tell your mechanic to fit in a 2012 honda cross tour engine
