Most of the time, intake air temperature is not the same as ambient air temperature. This is because the air absorbs heat from the hot engine bay area before the intake air temperature sensor (IATS) measures its temperature.The heat-soak effect typically worsens on hot days and when the engine is under high loads. Another factor to consider is that the ...

The Lojack is what is called the "aftermarket" in the automotive sales world. This is just one way a dealership will try to rip you off when purchasing a new (or used, for that matter) vehicle. When I say "rip you off," I'm not saying that the product doesn't work as advertised, as I'm sure it does. What I'm saying is, they mark up the price on such items to ...

I'm a little concerned by the proposed fixes. While I don't know the specifics of your Merc, I find it odd that the timing chain would be responsible for fuel trim codes. The ECU swap seems to be a concerted attempt at what I like to call 'parts roulette': possible, but not probable. If you have codes for fuel trims and misfires, the principal components ...

1) Since my ABS light isn't on on my dash, can I safely assume that it's fine as-is, or is this something that will likely come back to bite me later on? Yes. If the sensor was not picking up the signal, you won't see it at first (after the self diagnostics are done, that is). Once you start driving, the computer will notice the differential and then ...

I think you misunderstand the purpose of the Mass Air Flow (MAF) sensor (and whoever wrote what you read doesn't understand, as well). The purpose of the MAF is to read the amount of incoming air. As the incoming air flows over the heated sensor, it cools the sensor which regulates the amount of electricity which can flow through it. It is in no way ...

This is normal behavior for some vehicles. They utilize the fan to further cool the system after engine shut down (even though it does not further circulate the coolant). This is something I would not be worried about.

OK, so it seems like the IAT on this model is integrated with the MAF:

If your engine is the ABA engine, it's located in the distributor. You have to disassemble the distributor in order to get it out. For the money, they suggest it's a good time to replace the entire distributor. (NOTE: I'm not promoting that site ... please do your research and get what is right for you. Please notice what is said on the line for the sensor, ...

i just had this dumb problems fix for good, for months even after i change the sensor at the mirror the problems of erractic temperture keeps coming back. today my mech took the bunch of socket out between door and the car body spray some contact cleaner and blow off any access with the pressure blower for abt 15 sec ......wah lah all back to normal , this ...

By looking at some French forums it seems the outside temperature sensor is located on the bottom of the right (passenger side) mirror, and is a standard NTC thermistor. The signal is analog all the way up to some computer located inside the car, and the freaky values mean either the thermistor itself is dead or its cables are damaged. It can't be a ...

LoJack can only be installed by authorized installers. The price of installation is fairly consistent. OnStar and other similar services offer a similar feature set, but are not necessarily as secure. OnStar now offers an aftermarket upfit system that can be installed into any car or truck (not available for motorcycles/scooters, while LoJack is). A ...

All the analog gauges work by sensing varying resistance by a float sensor which eventually results in thermal conversion or Voltage mapping to fuel levels. The accuracy suffers due to non-linearity of these float sensors.The methods mentioned by Nick & Mac are right here; but it gets very tedious if your demands of accuracy are nearly 1% of total volume ...
