IAT Sensor

[i eat hybrids]

Do you guys know where it is at on the v-10? I check eng light is on and i took it up to autozone and they said it was a IAT sensor or MAF sensor.

Post the exact fault code.

The idiots at autozone aren't mechanics.

The codes are P0113 (IAT) and the other code is P0102 (MAF or MAP). Thats what the reciet says that autozone printed.

What year ?

I recently installed a CAI kit on my V10 - there was a provision for a seperate IAT, but on my V10, there isn't one.

I believe the intake air temp is done with the MAF on my '01.

But if there's a seperate IAT for your year, it would be in the air box, or just after it in the intake tube.

That code you posted means "intake temp high" - meaning the sensor isn't necessarily bad (code would say "circuit" in it), just that the air intake temp is reading too high.

Might have a dirty MAF if it's reading it off the MAF.

I just cleaned the MAF last week with MAF cleaner. I got rid of the stock cone and put an after market one on their. Its off my buddies 04 mustang, he gave it to me because he got a S/C kit for it and the kit came with a intake. So anyways once we installed the kit, we realized that he needed to use the MAF that was on my truck (the one that he gave me with the cone) so i had to take it off. I drove around without a MAF for 3 days until i put the stock one back on. The stock one is on now but with the aftermarket cone still on their. After i hooked up the stock MAF, i found that it was still throwing a CEL. So i took it up to Autozone and the codes that i listed are what they found.

BTW, its a 01

With all that mucking around, reset the PCM and drive it for a few days and see if it comes back.

Ok. Thanks ill try that and see what happens. Ill let you guys kno in a day or to.

Founds this on the site, hope it helps narrow down the problems for yea

"The P0113 code means your Intake Air Temperature (IAT) sensor is sending a voltage signal back to the PCM that is too high (over 4.6 volts)

As noted, the IAT is a thermistor device in which resistance changes with temperature. The electrical resistance of a thermistor decreases as the temperature increases, and increases as the temperature decreases, (proportionally in each case). This varying resistance affects the voltage drop across the sensor terminals, which allows for a voltage signal to be sent back to the PCM corresponding to temperature.

The voltage signal that is sent back to the PCM is equal to the Reference Voltage (VRef, 5 volts) minus the aforementioned voltage drop across the fixed resistor. That is why an open in the circuit between the PCM and the IAT will result in "too high" voltage signal at the PCM (i.e., 5 volts). In addition, corrosion in the circuit would tend to add resistance and hence result in higher-than-normal voltage at the PCM because of the signal being based on voltage drop.

In any case, if the circuit checks out OK, then it's either the IAT sensor at fault, or the PCM."

I didnt have time to unhook my battery cables over the past couple days (busy with work and FF school) So i just let the check engine light stay on. On the way to the FF acadmey today, i got into my truck and turned it on and the check engine light was off . Its been off ever since i got into the car this mornin. Thanks for the helpful tips!
