I am still checking this. I had already returned the scan tool I borrowed but hope to get it back for the weekend to check the evaporator temp sensor reading. I did do a visual check of the wiring and connectors behind the glove box and they look good.

evap temp sensor is mounted to the h-valve.

 

OK, I can't find the evap temp reading anywhere. I'm using an OTC Genisys tester and all I can find is A/C pressure, bus A/C select and A/C clutch sense.

So I checked the sensor resistance at pins 12 and 13 of connector C202 behind the glove box. With the A/C off it reads about 6.2k ohms. After jumping the clutch relay it reads from 10k to 25k, depending on blower speed and engine speed, so it appears to be working. Anyone have the resistance specs for this?

Thanks,
