A bad connection at the sensor (engine coolant sensor)
An open in the ground circuit between the sensor and the PCM
A short in the voltage feed between the sensor and the PCM
A bad PCM (less likely)
A bad engine coolant sensor


Hope that helps.

Yes, check all of these!


For the most frequent failures for that system that I've come across, it has been the temp sensor. I keep a half a dozen of them in stock and if you need one or just want to talk about that code, 914-763-3136.

I respectfully defer to a man with more knowledge than I have.

In brief....what he said.
