I have a 2004 Durango 4.7 magnum engine 4x4. Received a PO325 Code (Knock Sensor Malfunction (Sensor 1, Bank 1), but when I went to change the sensor, there was a bolt in a hole, but no sensor and no wires or clips to plug into a sensor if there was one.

I thought I read somewhere that the magnum motors don’t have a knock sensor in them.

If PO had removed sensor, how did they trick ECU to miss it for years till now?
