Re: Inlet Air Temprature Sensor Challenge

OK, thank you for the very informative information, I am learning so much. I measured the voltage agian and with the IAT plugged in it was 2.72 volts. measured it without the IAT plugged in and it showed approx 4.87. So I believe the system is sending proper voltage and the resulting voltage is ...

Re: Inlet Air Temprature Sensor Challenge

I believe so, I measured the voltage across the sensor. Went for one side to the other. Is there a particular voltage I should be looking for? :?:

Re: Inlet Air Temprature Sensor Challenge

Hello there, the voltage is 4.82 volts dc. Is this normal? :RTFM:

Re: Inlet Air Temprature Sensor Challenge

Thank you for making this clear I was not sure how it read the resistance and now I have a good picture of it. I will check it tommorrow and let you know. Do you happen to know if the ECU is bad where I can get it fixed at? Since it is a microsquirt I am leary to break open the sealed case.

Thanks ...

Re: Inlet Air Temprature Sensor Challenge

I am not sure what you mean by voltage, I thought the sensor was resistance measured. The part I am using is the DYI autotune GM open IAT, the only number I can find is the 5040 number on the senor it self

Thanks

Re: Inlet Air Temprature Sensor Challenge

There are no changes when I disconnect the IAT. The MAP sensor and the TPS sensors work perfectly. The coolant temp is stable and registering correctly. Not sure if there is a way to retrieve the temp table from the EUC to see if it even has the proper information. Have you seen this before?

Inlet Air Temprature Sensor Challenge

Hello,

Good day to everyone.

I am working on my porsche 911, 1983 SC efi conversion. Using the Microsquirt and all is well except that my Inlet Air Temprature Sensor is not being read at all by the ECU.
Using the GM-Open sensor from DIYAutoTune site. I have wired it directly to the harness and I ...
