94 Vette Coolant temp sensor
I've replaced the sensor on my friends 94 Vette, but it is still throwing a check engine light. The scanner shows a temp of -40. Is there somewhere I can get a wiring diagram for this car? Has anyone had this issued before?
Thanks

I'm not sure if it's any different in the Corvette's, but on the f-bodies the sensor in the water pump (not the driver side cylinder head) drives the PCM while the sensor in the head drives the gauge on the dashboard.

Make sure you have the right sensor. I ran into trouble when replacing mine b/c no one could give me the correct one, I always ended up with the 2 prong w/p sensor instead of the 1 prong coolant temp sensor.
