P0325 OBD-II Trouble Code
Technical Description
Knock Sensor Circuit Malfunction
What does that mean?
A knock sensor tells the engine computer when one or more of your engine's cylinders are "knocking", that is, exploding the air/fuel mixture in a way that delivers less power and can be damaging to the engine if prolonged. The computer uses this information to tune the engine so that it doesn't knock. If your knock sensor wasn't operating properly, so that it was always indicating a knock, the engine computer's response may have been to change the ignition timing on your engine. Knock sensors generally bolt into or thread into the engine block. This P0325 code may show up intermittently or the Service Engine light may be lit constantly. Other knock sensor related DTC codes include P0330.
Symptoms
You may notice drivability problems including a lack of power and perhaps some hesitation. There may also be other symptoms.
Causes
A code P0325 most likely means one or more of the following has happened:
* The knock sensor is faulty and needs to be replaced
* There is a wiring short/fault in the knock sensor circuit
Possible Solutions
* Check the resistance of the knock sensor (compare it to factory specs)
* Check for broken/frayed wires leading to the sensor
* Replace the knock sensor
and
P1149 O2 Control (Bank 1) Out of range
i'd replace the O2 sensor on bank one sensor one (unsure of what bank is which but sensor one is the one that is closest to the block, between the block and the Catalytic Converter. most of the time bank one is driver side, but in a transverse mounted engine i would assume the exhaust that is closest to the front of the vehicle.
