So with thoses codes P0325 is Knock Sensor and P0131 is O2 Sensor Circuit Low Voltage. Both codes come up at the same time the Service Engine Soon light comes on. I can errase the code and drive it for a week or so before it comes on again giving the same two codes. Is there any thing that should be done to the engine quickly as it seems to be running okay. What does O2 Sensor Circuit Low Voltage mean. Does that mean I have to change the sensor itself or is that an electrical problem.The Knock Sensor had been replaced before at around 205,000 kms
