CAN BAD TEMP COOLANT SENSOR MAKE THIS CODE PO135 COME ON IF U CAN EMAIL ME BACK AT [email protected]

Answer 1

Hi there,

The coolant temp sensor could cause the P0125 code, and if the engine temp is not up to the proper operating temp it could affect the O2 sensor. I would check the thermostat first though. If it's stuck open then the engine will not get up to temp.
