"Coolant Sensor is bad"

Okay, I get a message on the onboard computer that the "Coolant Sensor is Bad". I changed the coolant sensor located on top of the motor near the thermostat housing, still getting the code. Got any idea's?

It's the sensor in your radiator overflow. Just cut the wires and stick them together.

There's a thread or two on this, it's a common problem. If you changed your sensor and it's still a problem, you may have to repair your VIC.

I have the same problem, haven't dealt with it yet. Apparently though, simply connecting the wires together may not work, as the sensor should have 33k Ohms resistance in it. So, you could silence the offending alarm by putting a 33k Ohm resistor between the two wires.

Good luck!
