Question type: Maintenance & Repair

How do you reset the PO15 code  (Open Coolant
Sensor) on the code reader

3 Answers


Once you fix the problem it will turn off in about 20 cold starts, or you could just remove a battery cable for about a minuet, but you will loose the presets for the radio, heater etc.

Did that but the engine temperature coolant is not displaying on the information control center


Then there maybe a open in the circuit.
