Question
I downloaded a P0128 OBD code, pertaining to erroneous coolant temperature to the engine computer. I understand there are two sensors. Where is the engine computer coolant sensor located?
Thanks in advance!

The water outlet housing,by the thermostat.Just because you have a code for the sensor is it really the sensor?You sometimes get codes and the first thing people do is to replace that component when in fact it is something different.Make sure you check all the possibilites before replacing parts

| Comment | It would be great, since you mentioned all other possibilities need to be explored before changing the coolant temp sensor for the P0128 code, if you could list some of them. Is there anything else other than the wires between the sensor and the ECM? b727engineer@aol.com | ||
