P0325 Knock Sensor Code in 2005 Chrysler Town & Country 3.3L: No Check Engine Light, No Knock Sensor Present

Model: Town and Country 2005 3.3L Fault Code: P0325 Posted: 2016-01-22 17:39

I recently received a P0325 knock sensor circuit fault code from my OBD-II scanner. Notably, the check engine light is not illuminated. After clearing the code, it reappeared immediately. I need to complete an smog/obd compliance inspection soon, as this 2005 model year Chrysler Town & Country does not have a traditional knock sensor according to factory specifications. The vehicle runs smoothly and shows no performance issues. I have already replaced the camshaft position sensor, powertrain control module (PCM), and crankshaft position sensor. Despite these updates, the P0325 code persists. I'm at a loss as to why this fault is appearing, given that the engine should not have a knock sensor in this model year.

The knock sensor is typically located on the engine block, above the starter and toward the alternator, with threaded mounting holes into the block.

I will investigate further—many sources confirm that the 2005 Town & Country 3.3L does not have a knock sensor, so this code should not appear under normal conditions.

I'll keep you updated—I’ve checked my service manual for location details, but the parts manual doesn’t clearly identify or confirm the presence of a knock sensor in this model.
