So this morning on my way to work the check engine light came on in my 96 GT. I had the codes read over lunch and it said (along with a code for catalyst effeciency) that there was a fault in the coolant temp circuit. The dash gauges has always worked so I'm assuming there is a sensor for the gauge and a sensor for the computer.

 

Also, I do know the location of at least one of the sensors. There is one installed on the passanger's side of the coolant crossover pipe. I'm assuming this is the one for the computer yes?

 

Thanks for the help.

The ECU sensor has two leads and has probably (if it's like on my 96 2.2L) a dark red connector. The gauge sender is, IIRC, just underneath (at leas very very close) and has only one wire going to it.

Yeah, the one I can see (and purchased) has a dark red connector with two wires.
