What would be a typical symptom for a malfunction of this Coolanttempsensor? I am still elaborating on this and get no plausible resistance values according to your (Volker) target value table. However it is not evident that this is the root cause for occasionally warm idling issues.
At any Temperature it is at 32 Ohm??! The gauge is adjusted to 2kOhm and it shows 0,032 at 80 degree. I checked that on any other temperature down to 30 degree without a difference.

Hi Mitch,
do you read out the resistance with the sensor connected to the ECU?
Unconnect it...

Regards
Norbert
