Do you have a check engine light on with a TP related code?
Here is my TP position at idle.. Nothing is wrong with my car

Check my own accord TPS pid value too at idle .Your TPs value is on point .

olumzzz:
Madam radautoworks,
I scanned my car today and my TP Sensor showed 12.9% on idle. Does this mean that this sensor is faulty because i read online that it shouldn't be more than 5% at idle.
Car is Hyundai Elantra 2008.
PS. I get rough idling at startup for about 20 seconds then engine stabilizes.

There is so many mis- information on auto matter online .Don't believe everything you see online .TPS pid value is at prerogative of the designer of that particular brand ,there is no fix value for TPS across brand of vehicle .
Issue like misfire will cause rough idling ,leave the TPS alone

..i will put net or straight pipe as advised

Don't put net to avoid choking your engine to death , you can decide to leave it hollow .

Pls house i need more experience bcs I'm right now Confused...I'm using Toyota sienna space bus bt d problem with it is highly consumption of fuel....After diagnosing it...d culprits was spark plug and injector mouth, After changing those....I'm still nt satisfied with d result...ever since then evry mechanic do tell me to buy catalyst of which i did....But real concern now is that i should av leav it as it was before buying catalyst....the vehicles is running smoothly but consuming much fuel after putting cat.....someone now advised to remove cat and leav it empty so see d different...and after removing it d fuel nw come back to normal..... my question now is ..... Is Catalyst converter Overhyped or is it working differently with d system of cars?.....pls i jst wnt to learn o

Thabks guys, please any reliable mechanic to help with the first option and and what can be the cost estimate

Contact my no and autologic will give u life time guarantee on the fix .

jodeci:
P0420 is a catalyst related and will.not cause any drivability issue.However, your car will be louder and tastier.Expect a. Marginal increase in fuel consumption

I respectfully disagree about marginally fuel increase for 1zz Fe engine cos the research team in autologic have personally take the time to do test for that model of vehicle and their conclusion is that effect of removing of cat is not significant for fuel mileage and if a user notice considerable fuel decrease with P0420,
What is likely to be responsible are
1.Restriction due to presence of faulty cat which will trigger p0420 as well .
2.other latent issue issue that is yet to be diagnosed

The code is an indication of issue with your catalytic converter which might be due to its absence or it is present and faulty .
You need to confirm first if exhaust system is still carrying the faulty cat and it is important that you remove this faulty cat and so as to prevent exhaust restriction In nearest future ,and the decision now lies with u now if u want to replace with good one or you want to make the exhaust hollow without cat and insert device that will address the P0420 code once and for all .
Absence of cat will never cause any drivibillity issues ,it is primarily for emission purpose and for reason of being environmentally responsible ,we must ensure cat is installed .
Yes cat is pretty expensive cos it is made up of precious metals

The best way to save fuel is driving making use of deceleration mode of driving cos at deceleration ,ecu commands injector to cut supply of fuel .

From my findings, if you recently clean throttle body which I did, one must relearn for the ecu to understand. That's the solution provided yoh clean throttle body

Camry 2000 throttle system doesn't lend itself to ECU relearn .Just service the throttle assembly and idle system and it will automatical adjust itself to spec ( if it has not been kazeemised)

haykay2005:
Currently having similar issue . My car vibrate towards the engine bay at low rpm especially when am applying break. Most of the time when I put on the AC. The vibration goes away at high speed. I just serviced the car and no code whatsoever. New plugs, throttle body cleaned, new fuel filter, no fuel pump problem, engine mounts in good shape. What could be the problem pls?
1999 toyota camry

Service the idle control valve not only the throttle body .
ECu uses the idle control to add resources(air & fuel) to the powertrain system when extra load is being added to prevent the car from dying off and also any unnecessary vibration at low rpm for drive- by- cable throttle system.

Just electrical issues or general car issues?
This one go hard to tackle remotely ooO.
I've seen cars that would give the manufacturers headaches with the way wires would be flying around and taped with pure water satchel.
Have you also considered that most people ignorantly buy a poorly converted car here too?
Electrical components dey broad and are the most abused parts in a car ooO.
It would be fun watching how solutions to auto electrical issues are being proffered here though.
Following.

Apart from suspension issues and engine related ,all other vehicle issue is 90% electrical related eg Performances issues , fuel mileage,HVAC ,cooling etc are all electrical related .If must know for modern car ,the fault management background system is OBD2 run on electrical platform .

The fan blower level has control over the compressor ON time. For example (hypothetically), if fan is put at level 1, when compressor clutch engages for 30 secs it goes OFF for 10secs and continue to toggle at the same rate. But when you increase blower level to 2 it also increases the clutch engaged time say 40secs ON and 10secs OFF. At level 3 you get say 60 secs ON and 10 secs OFF then at final level you get say 90secs ON and 10 secs OFF. Some cars come with MAX AC button, this is the bypass button to the clutch and keeps the AC clutch engage full time unless there is too pressure in the system then the pressure switch stops the ac system completely till normal pressure is achieved. In that case, most ac ON lights will blink to show system problem.

Therefore, the fan lower level will also determine fuel consumption since it controls how long the ac clutch remains engaged.

Lastly, i think the message op is trying to pass is that driving at high speed using ac which means winding up will balance out or even be more economical to air drag when you drive without ac and your windows down in terms of fuel consumption. I have compared this severally and it works. You will use roughly the same fuel in the 2 instances.

Let me make some clarification to your statement about the relationship between the fan blower speed and the compressor turn on time .
1. For the AC design you are referring to , The AC control module uses the input evaporator temperature sensor signal to determine the cut -off time of the compressor .The cut off time of compressor is not based on certain arbitrary time as you assume but based on set evaporator temperature .That is when the blower fan is increased to higher level ,the AC module will set the evaporator temperature that the compressor will cut off lower and vice versa .
2.The FDC compressor working as opposed to the VDC is 100% that it is putting all it %100 full capacity to the pumping of refrigerant.Hence some infrequent cut off it experiences when the evaporator set temperature is reached occurs for few seconds and will not be significant enough to use that as saving fuel grace as u assume .
This is why manufacturer came up with design of the VDC compressor to give a better mileage as the pumping capacity of the compressor can be varying from %1-%100 based on alot of set algorithms which is based my user "needs" instead of the ancient old FDC technology that can never reduce it working capacity other than cut off for few seconds which doesn't make any significant contribution to fuel mileage.
3. Then finally talking about the message the op is trying to pass across ,check the topic of this thread ,I feel he should edit it to pass clearer message across cos the subject of the topic is misleading and erroneous .
Better topic should have read like this " You save more fuel when you wind down your window "
The essence of the experiment is actually on the effect of air drag on fuel ,the use of ac is just a control aspect of the experiment not the subject .

@Op You got the essence of the experiment wrong and I think you will need to edit the topic of this thread not to mislead the general public.
The essence of this experiment is to show that a car that has its window open even without ac on when speeding at higher speed around 100 km/hr will consume more fuel than another car that it window is closed even with the AC kept on .
What they actually want to prove is that dragging force that enter a car when the windows are opened is very substantial and even greater than when you close the window even with ac load when traveling at high speed .
To set the record straight ,Any load on the car whatsoever eg ac compressor and basic accessories like lights ,power steering ,wiper etc when turn on will increase the fuel consumption of car and the consumption will depend on the current the load is consuming .
So traveling at high speed with ac will always consume more fuel than when ac is not on so far the windows are close for both instance .
Lot of technology breakthrough has been introduced to reduce ac load by introduction of VDC compressor and dedicated ac module just to reduce the load of ac compressor but it impossible to achieve zero load with ac cos of law of conservation of energy.
Finally , let me add to this piece by stating that reducing the temperature of ac and blower fan speed just to save fuel will only be effective when dealing with the VDC type ( automatic ) of compressor system but is not significant when u are dealing with the FDC compressor (manual compressor )

I'm having the same issue currently with same Camry Orobo . I have service the injector and yet no difference. I was asked to buy a new SMOKING SENSOR with I'm planning to buy tomorrow. Now seeing yours, I wondering about the vacuum lines rearrangement. Not sure how to go about this though. Please help.

Find techie with some level of reasoning to do a proper diagnosis test for your car and stop patronizing illiterate kazeems that labelling map sensor "smoke sensor".And even if u got the arrangement of your vacuum lines right doesn't point to the fact that the issue with the car , symptoms can be the same but root of issue might differ.

What about in America? Is it the best selling thing there. Before it will be number 1 in the US, they would have dumped all their fossil cars on us. The phev and hybrid cars are not working properly in the country and you say that electric cars is the future. We are busy copying these them and their situation is not the same as us here. Tomorrow we will ban cars driving into alausa because Paris did the same thing.

Typical African only think of their present needs ,not so much concerned about the future or even planning for next few decades ,no wonder we are so backward intellectually and technologically ,no forward thinking plan at all ,what a pity .
The sole reason for EV is solely for environment and emission which which largely affects our health well-being and survival .
This environmental factors is what brought about the partial zero level gasoline vehicles ( SULEV,LEV
etc I) found in today's modern a cars which relies heavily on computer systems and modules ,which eventually replaced the ancient old mechanically driven carburetor engines . People with myopic view too cannot fathom the possible wide adoption of computer controlled nowadays modern car to replace the dianosour carburettor cars but they were proved wrong eventually .
Demands bring about technology innovation and eventual reduction in cost of productions ,check the stastics in demands of EV in US ,it is increasing geometrically ,it is a just a matter of time that it will surpass the old school fossil fuel powered vehicle .
Yes we are reactive people and we will be forced to follow the same pattern adopted by sane cline to have a reasonable emission law that favours EV when we start to have environmental issues caused by vehicle emissions ,it is just a matter of time thanks to our increasing cars population.
Recalling from history California formulated the strictest emission law and best safety standards that we see today in US spec car not for economic reasons but survival .

Wether u want to believe or not ,EV is the future and the technology is getting cheaper and better everyday .
EV is the best selling car right now in Norway ,similar country like ours that has has abundance of crude oil deposit .
Serious thinking countries have committed huge resources and setting the right policy to encourage the disruption of vehicle technology in favour of EV and slamming huge tax to discontinue the production of fossil fuel powered vehicle while we still debating whether is feasible or not .The future is much closer than we think .

Joehigashi:
sir,can you find time to come check it? can you come diagnose and fix? please let me know how convenient it would be for you.thank you

Call my no @ signature for further discussion

Joehigashi:
autologic could this be a mechsnical or electtical issue?

The transmission module will need to be scanned and certain pid checked on live data with a professional scanner to ascertain this.

Newbreed2018:
please sell off. The earlier the better. Nissan nor be car.
Don't say u weren't warned.

Is not about the car .it is about the untrained Kazeem and the uninformed car owner that prefer service of Kazeem for a complex system like a transmission system.

blackwood:
Since you have no scanner around you, it would be difficult to pin point the problem. I had a similar problem with starting my corolla and most auto electricians were asking me to change the brain box but I doubted them.
I solved mine by changing the crankshaft position sensor and Coolant temperature sensor and I've had no problem ever sseeo have a good battery and your injectors are in good condition.

I respectfully disagree ,scanner is just like other tools to increase the efficiency of doing work .Too much emphasise on this scanner thing self ,it is the human brain that diagnose, analyse and fix and not tools . Scanner and other diagnoses tool are mere data retrieval for human analysis. Atimes your scanner is even useless at certain situations or cannot even access the system or is throwing codes not related to the problem or is not one complaint and so what do you do in those situations?You go back to the basics to fix the issue .
If a techie is unable to fix a certain issue it is not due to lack of owning a good scanner or other tools but due to lack of basic understanding of the problem
If the basic foundational knowledge of "known good data " is known then the rest is easy .

BishopSal:
I will want experts in the house to help. For weeks now my toyota matrix 2005 has had starting issue. It will cramk but wont start. But sometimes it will start. The electricians have tried to find the problem but no solution. They've made me change the brain box but the problem is persisting... any expert advice pls will be very helpful. Thanks

Get a electrician that knows how to handle basic multimeter with knowledge of basic electrical and give me a call ,i can give you a remote support in my spare time .

I know this guy well well.

He is lucky to have come from a very very supportive family. His dilligence was easily rewarded. He was light years ahead in terms of exposure compared to his engineering/tech course and faculty mates.

He was able to travel faster than most of his contemporaries.

He is an extremely private person so i am even surprised his pics are on social media.

Wish you well. Andfash!!! Na Mikolo dey talk.

Yes o ,,shout out to great ife peeps

Symptoms of coolant going down is a clear evident of leakage and leakage can be internal or external .U need to find a 21 century workshop that can perform cooling system pressure test to dig out the root of leakage .
Pix shown above depict the tool at work .

niyispage2017:
Its will be great to help you sir, for your can to be diagnosis, I have to put the diagnosis machine on it in other to know what is the actual problem on that car . My diagnosis is at a cheaper price . So you can contact me on 09050523959

Seems u don't even understand what the issue entail .No need for any scanning here .This is totally an electrical troubleshooting ,what is needed is Multimeter ,manufacturer wiring diagram and brain for analysis .

Calapar:
Hello guys

Please I noticed that radiator fan of my Toyota Camry XLE 2012 keeps working after I turned off the engine. What could be the cause? Has anyone have similar experience?

4 cylinder or V6 ?

The AC compressor is designed to be turned on by the AC compressor relay via the PCM.
PCM gets the turn on signal via a bus communication signal from the HVAC switch on your AC panel that your switch on.
For a contantly ON compressor that means short to power or ground has occurred along the signal route.
To troubleshoot this and identify the culprit ,you need to start to unplug or removing all the element mentioned along the route aone by one till the AC compressor goes off .
