I need a very good rewire that can work on Acura mdx 2009 model in Abuja. The car is having issue in kabba kogi state. It's very urgent pls.


Thanks all

Look for autoelectng .

jayrock:
Pls I really want to know the implications of altering the electrical system of a Mercedes Benz Car e.g C200 Compressor.

1:will there be any further crack down
2: what will happen to its performance

Kindly help if you have any reasonable answer as no insult will be welcome.
Thank You

No way this your kazeemisation project question will not attracted insult ,your question is like asking if a doctor remove your brain and put under your feet ,you go normal again ?

Costee:
But we are not talking of 2008 Pathfinder here. Yes, the same principles, but different circuit configuration. I've not checked but if we were to search for the part numbers of the TB for the two vehicles I'm sure they won't be the same.

Sorry my mistake I thought the vehicle under consideration is Nissan Pathfinder ( I just finished one recently ) ,it actually a Nissan Murano 2005 ,I will make the necessary correction accordingly .
Yes it same principle of operation

Costee:
And speaking of the throttle motor drives (pins 3&6) in the ECM, I'm wondering whether the OP posted the entire error codes. If for example the drives are burnt in the ECM the car would have no acceleration at all, which is symptom under reference. In which case a new ECM will be needed.

Point of correction ,pin 5 and 6 are the throttle motor drives not pin 3 which is TPS2

Costee:
All well, though there's always a danger in using generic sources as you've done.
For this vehicle
Pin 1 is the ECU feed
Pin 2 is for TPS 2
Pin 4 is for TPS 1
Pin 5 is for Ground
3 & 6 are for the drives of the throttle motor

What i put forward is not generic ,source is excusively Nissan Pathfinder 2008 service Information hi .
I deal with service Information not generic and my signal testing will never be accurate unless I am be guided by Nissan dealership service Information
Anybody with similar can use terminal info below to confirm .

To continue this piece
Pls click "like " if I am making sense or click "share" if I am boring you so that I can stop right now .Beside I want to go back to work(customer are waiting)
Below is the view of the terminal connector of the throttle assembly .

Let now explain the principle of operation
1. When a car user depress the throttle system ,there is a APP(acceleration position Signal assembly ) that record the angle of depress and send the signal electrically to the ecu .
2. ECU takes the signal and send it as output signal to actuate the throttle motor (pin 5 and 6) accordingly to correspond to the position of angle of the APP to depict the depresing angle of the user .Kindly note that this signal cannot be read by simple multimeter cos it a varying signal (pWM ) you will need a labscope to view it .
3. The ecu will need to know the corresponding angle of opening of the commanded throttle motor to know if the throttle motor actually carries out the command successful and so it will need to make use of the TPS1 and TPS2 as feedback to know this
So TPS1 and TPS2 will now send the corresponding input signal to the ecu to reflect the true throttle angle of the throttle motor .
I will now explain the troubleshooting in subsequent page .

A typical electronic type throttle assembly is a 6 pin terminal connector and takes all it output and input from the engine computer (as opposed to the cable type that is 3 pin ) and what each stands for are summarised below:
1. Pin 2 = Costant 5 v reference signal (ecu power feed)
2. pin 5 = 0 v low reference single (ecu signal ground)
3.pin 1= TPS1 first input signal to the ecu (TPS signal 1 to ecu ) and theoretical ranges from 0-5v
4 Pin 3 =TPS2 second input second to ecu (TPS signal 2 to ecu ) and ranges from 0-5v (theory)
5. Pin 5 and 6 = PWM signal to drive the throttle motor to open and close (ECU actuator output signal)

Ogakazeem actually spoke my mind .
The greatest knowledge gap that auto technician are currently facing not only Nigeria but worldwide are "detail knowleage of principle of how things works and it's relationship to the electrical architect of the vehicle and even to the extent of intermodule communication ".
Scanning a vehicle is just small fraction of many test procedure to diagnose simple fault like this just like a what typical stestscope to a Doctor ,which is to give clue to the faulty system but cannot tell u to minute detail the fault., further test is required to get to the root of the problem .
Scan tool is purely a data retriever and test tool and is just like a sidekick to a superhero and not superhero itself .You are the superhero that will analysis the issue base on data received from scanner and other diagnosis tools like your Multimeter , Labcope and most importantly armed electrical foundational knowledge of what transpired in the background of the system .If you are armed with the right knowledge ,there is no limit to extent of Kazeemisation of a messed up vehicle you cannot undertake its restoration project to manufacturer specifications and even there is nothing stopping you for taking on any brand of vehicle and year as early as obd1 vehicle .
You don't have a business even repairing a toy car if cannot understand to detail the electrical circuit and signalling process that goes in background of any system cos you are going to be goofing around changing parts based solely on what your scanner DTC is telling you which doesn't differentiate you from a typical Kazeem despite investing in millions of naira professional scan tool.
Also,I will like to add to this piece that it is professionally wrong to be advising people that have issues with their car to be changing parts based on the scan DTC they give ,it is amateurish and not professional cos a lot of variable are involved which you won't have info about unless u actually see the vehicle physically and perform the needed test .
That you have guess right before doesn't apply to all situations .We can give point out area for them to concentrate their effort on but not to give advice on part changing .
Let me dive on how a typical architecture of electronic type throttle systems assembly of vehicle and Nissan peculiarities and the areas the ops will need to concentrate effort on .

I have a Nissan Murano 2005 Model, its giving me a hell of problems. When the ignition is turned on, it refuses to raise while you throttle it. Its been scanned and its showing TP Sensor/circuit and Power/ Circuit. I've tried changing the injector mouth severally but to no avail, Some mechanics are talking about changing the gearbox, does the raising of the engine has anything to do with the gearbox? Its killing Me slowly, please help a brother. Even any Link to any better Electrician(expert)

I will advice that you don't start throwing parts based on scan DTC ,it is a pure electrical issue probably a short circuit that need further probing ,we can help you with the fix if you can if you book appointment with us at autologic.
The reason are suggesting change of transmission is that they know from experience that TPS has something to do with the transmission but cannot really explain how ,so it as well be a fatal mistake to go ahead with such terrible advice of change of transmission

Thanks for the patronage

Good Morning,
Please I was washing my car and I decided to check the Engine. Immediately I discovered this wire linked to a fuse has cut and melted. I started the car and it started normally. What purpose does the fuse serve and is it risky taking the car out to church this morning.
Please I need urgent answer.

Your ignition coil during operation produces unwanted ac components signal technically refered to as "noise" and the essence of that capacitor is to removed those noise as to prevent those noise causing intereference or signal jamming with devices that operates at high frequency like knock sensor and radios , Hence their is possibility of occasionally "pinging" or "knocking sound " due to intereferences with knock sensor signal,however you can still take the car to church but ensure the naked end of the wire is not touching the engine body ,.insulate it properly .

Good morning

Thanks for the patronage !

AutoMoTech:
This is what baba is complaining about. Not "Service Engine Soon"
Bt still like i said earlier, since he just got the car, he needs to scan the car and fix whatever needs to be fixed.

Baba is one that paraphrasing " Service engine soon " to "car now due for servicing " unfortunately there is
no error alarm like that on any Nissan instrument cluster .So dont get confused by Baba statement .
All Na still "check engine"

naphunlimited:
Different opinions have been said about the radiator fan switch. Some say that it is the thermostat in a car, others say that it controls the radiator cooling system.

Please if anyone can throw some light on how the radiator fan switch works, like what it really does, its effect on gas millage and so on.

Your contributions are highly welcomed.

The technical jargon for that switch is being referred to as "Thermoswitch" as seen in Camry 2000.
Depending on the design of the car ,not all car use switch for control of their cooling fan ,tsome fans are are ecu controlled tru a relay while some control the fan tru a dedicated computer module , assume you have mentioned the particular car model under consideration it would have been better for clarity sake.
However ,fan control is not the same with thermostat,they perform different functions and while the former is an electrical device ,the latter is a mechanical .
The essence of fan control is maintain the car at optimum working temperature and take out any excess heat while thermostat enable the car to build up heat and reduce emission for best catalystic converter efficiency during engine start up.
Temperature is very paramount for the working condition of a vehicle which is the reason for that words "optimum " cos anything outside the optimum range wether below or high will spell doom for the engine and cause excessive high fuel consumption .
If you need to read more on how fan affect fuel consumption ,u can look up on this thread

I have a 2010 Highlander & have a brake malfunction warning on the screen. What does that mean?

If your abs light is on as well then it is the abs light that trigger the brake light otherwise check the brake fluid switch

Pls endeavor to specify your car model

avicky:
@automo tech.. I'm a newbie in driving and owning a car. Please, I serviced the car, changed the engine oil and a that but the check sign is showing in the tachometer.

Check engine light indicator is powertrain issue not oil change .Scan and resolve the problem and the check light will disappear.

Canadanow:
Weldone bro. I changed my timing belt and water pump and my car brought a check engine light but my car is running smoothly for now. No overheating and no water leak anymore.

I scanned it and the code was P0018.

Erase it and check if the code reapper and if so then the the timing is not yet correct

Ambalicious:
My car suddenly went off while negotiating a full turn a u-turn. It happened twice today.

You need to state the model of car for easier analysis , however what will make a car to go off this circumstances is unexpected load on the vehicle powertrain system which the ecu is unable to make compensation for or the compensation is made but not reflected on the output .
Check the throttle system assembly for dirts

Lexusgs430:
Some vtec engines drink oil, like puff puff soaks vegetable oil....... So that oil shortage might not be directly attributed to engine wearing out.......

No reason for vtec to be drinking oil unless the seal is leaking ,and then what account for the engine Smoking if not piston ring issue or valve seal .
Appropriate Diagnosis will get to root of the issue if the op is willing to toe the right part or maybe he prefer parts throwing instead

My Honda accord evil spirit started smoking after topping the engine oil. I travelled l to abeokuta from lekki yesterday but I noticed my oil wasn't Guage, I had to buy 1 litre of oando oil to topped the synthetic oil I was using before, thinking I would change the oil when I'm back from the journey, I got back late and noticed on my way coming that my car was smoking. Have changed the complete oil today to synthetic and still smoking. My rewire said it has affected one of the rings. Please house what can I do to make the smoke stop because I don't want to ring the engine.

Thanks

Topping your oil is a indication that your engine is already wearing out and is not a sudden thing as you assumed,the issue has been there ever since.The wear and tear has degraded to the next level which is why u seeing white smoke .Since average Nigeria is reactive towards maintainance rather tthan proactive then no need trying to save the already split milk cos the engine is already on it way out ,just trying save towards getting another engine.

What are the symptoms of VVT issue or how can bad quality engine oil affects drivibility of vehicles.

VVT issue arises due to use of low quality or bad oil is one of the most complicated issue to fix.
The issue is beyond what ordinary mechanic can fix ,so it it just better to avoid such expensive repair and adhere to best maintance practice by use of Lubex synthetic oil and other high quality oil .

1.VVT solenoid
2. VVT actuator

VVT is the recent technological breakthrough in automotive engineering that make use of varying timing in automobile engine to optimise performance to its at peak and yet still achieve the best fuel consumption .
Implementation of this beautiful technology is based on use of hydraulic energy from engine oil .
To maintain and have the best of VVT advantage ,the engine oil must be of
1. manufacturer recommendation
2.best quality ,
3.free from dirts and sludge free.

Beautiful Sunday morning .

How can one get OEM replacement and cost

Are u not tired of wasting money by this parts throwing ? Haven't u heard of diagnosis before ?
