The code means there is a problem in the knock sensor circuit, that means the the knock sensor connector wire pins may have a problem, the wiring to the sensor may be damaged, or the PCM may have a problem, and of course the sensor itself, I have one question did you tighten the sensor to the proper inch pound setting of torque? if not this can cause a code to set because the sensor does not vibrate as designed to send a signal of a engine knock/ping.

What is code 325


P0325 - Knock Sensor Circuit Malfunction
Possible causes- Faulty knock sensor
- Knock sensor circuit short to ground
- Knock sensor circuit short to power
- Knock sensor circuit open
- Faulty Engine Control Module (very unlikely).
P0139 - O2 Sensor Circuit Slow Response Bank 1 Sensor 2

Possible causes- Rear Heated Oxygen Sensor Bank 1 harness is open or shorted
- Rear Heated Oxygen Sensor Bank 1 circuit poor electrical connection
- Faulty Rear Heated Oxygen Sensor Bank 1
- Inappropriate fuel pressure
- Faulty fuel injectors
- Intake air leaks may be faulty
- Exhaust gas leaks

What causes a p 0327 diagnostic code on a 95 contour


P0327 - Knock Sensor 1 Circuit Low Input Bank 1 or Single Sensor
First check the knock sensor connector. If the connector is clean and secure, replacing the knock sensor usually takes care of the problem.

- An excessively low voltage from the sensor is sent to Powertrain Control Module (ECM) or Engine Control Module (ECM)

The knock sensor is attached to the cylinder block. It senses engine knocking using a piezoelectric element. A knocking vibration from the cylinder block is sensed as vibrational pressure. This pressure is converted into a voltage signal and sent to the Powertrain Control Module (PCM) or Engine Control Module (ECM).

Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Lack/Loss of Power

Possible causes
- Knock sensor circuit short to GND.
- Knock sensor circuit short to PWR.
- Knock sensor circuit open.
- Damaged knock sensor.
- Faulty Powertrain Control Module (PCM) or Engine Control Module (ECM).


Test and check it. Hope helps.

Why m I getting this codes p0135 and p0138


P0135 is 02 heater circuit ( Bank 1, sensor 1 ). P0138 is 02 circuit high voltage ( Bank 1, sensor 2). It is a good idea to replace all 4, 02 sensors at the same time, otherwise the 2 new 02 sensors on bank #1 will be transmitting Data back to the computer at a faster rate then the old ones on bank #2 And this could cause other problems. Remember to have the codes cleared from the computer after all repairs are finished. If you do not the computer will keep turning on the check engine light.
-also that way if the light ever comes on again you already know it will be for something new.Good Luck and have a good XMASS.
