I was leaving my friends shop today, when all of a sudden the CHECK ENGINE light came on. It stayed on for about 30 seconds and shut off. No power loss, no overheating, all guages, temp, oil pressure, voltage all normal. I checked the ECM and it gave me a code 14. I read it was a coolent sensor. I know they have 2 sensors one for the FAN and the other for the GUAGE. Is there a third for the ECM, or am i missing something??? Also if there is another sensor where is it located and what is it called so that the parts store dosnt screw it up??? Any and all help appreciated.

 

Any body??? Also If there is a third sensor, location or pics would be appreciated. And P/N if available. Oh Im sorry, the car is an 86 IROC 5.0 TPI if that helps.

 

coolant temp sensor should be in front of the intake manifold on TPIs.

 

Ok, went and got coolant temperature sensor today and it looks like the one in the front of the engine. My question is, do i have to take the Alternator out to get at the old sensor or does anybody know a trick to this???

 

there should be plenty of room to remove the old sensor without removing anything else. have a pan ready for the coolant.

 

Thanks for the response, Im gonna tackle that problem tomorrow. I would do it right now, but engine is too hot right now.
