I'm replacing the valve cover gaskets and came across this broken sensor (circled in red) curious what it is? Also, what is the yellow one?
Thank you

did your temp gauge work? if no the red one is for the gauge and the yellow one is for the PCM. i think they have different conecters so they cannt get mixed up and they are each different. one is a sender and one is a sensor. search a little more to find the difference. check the wiring, is one a 2 wire and one a 1 wire?

 

What is a PCM?
