Default Code 15 ... how do you fix this one?

I have a code 15 that is constant. Coolant Sensor Circuit (Low).
I have checked all of my coolent fluid levels and they are fine. What is the remedy for this code?

Thanks for the help.

Check wiring, connectors, thermostat. Monitor actual engine temperature.

If within limits, and wiring/connector is OK, change thermostat and/or sensor. :yesnod:

Code 15 is set when the coolant temp sensor in the front of the intake base shows a high resistance.

Pull the wiring harness and measure the resistance of the sensor; warm up the engine and measure again. If no change, replace the sensor.

I would just rplace the sensor. They are dirt cheap. Hate to say it but the company I was with last made them :bb

I had no part in the design of the parts to my benifit, I just cracked the whip to keep the employees cranking out the parts.
