This is the code that my car threw last night - P0113 - "Intake Air Temperature Circuit High Input". Car has been hesitant for a few weeks now, sometimes stalling when coming to a stop. Idles at around 2K on start up then seems to do what it wants, lots of little judders and pops, revs drop off on their own... like a haunted car lol. Have done ECU relearn/IACV clean etc etc. It runs alright for a bit and then this happens time and time again. Last night was the first time I have seen it throw a code.

Possibly worth noting that I was driving at around 40mph when the CEL came on, not at idle. I have since cleared it and it has not come back.

I have checked for obvious loose connections to no avail. Should I suspect the IAT itself? I mean would it cause such a rough idle? Im guessing its possible to read the resistance with a multimeter? Any ideas on the correct resistance range for a working sensor?

How much am I looking at for a new sensor?

Lots of questions, apologies for lack of thread composition, but I'm on my iPhone!

 

I have the test procedure from the service manual if you need it Chris.
Part of the routine is to test the IAT with a scan tool or measure the voltage (5V).
PM me if you need the detail.

 

Thanks, 11-47, I've printed that off and shal run through it tomorrow

 

That's the beast. Good luck!!!

 

I had a similar problem not so long ago, not only was it a loose wire on the ecu, the IAT sensor had come loose completely.


Its worth a check.

 

Jon thats the IACV - IAT is just above your wrist? I will double check my connections tomorrow. Have heard a few reports of the wires disconnecting in the harness due to a cold snap.... just some re soldering to do hopefully!

 

LOL, Fail, must have misread it.

anyway, worthwile checking your connections.
