Possible oil Leak at Knock Sensor


if I'm not mistaken, the knock sensor is mounted on the transmission bell close to the motor and detects the flywheel position. It is possible that the valve cover gaskets might be leaking from the bottom side and dripping onto the knock sensor, but it is also possible that the leak might be from the rear main seal of the motor. If that is the case, you will have to drop the ****** to replace the seal. If the knock sensor was bad your vehicle would not start at all, just crank. Try to wipe all the old oil with rags and look very closely where it gets oily again

I have on 01 xterra-service engine light on-codes P1126 & P0325. I think the battery is about to go,could it be realated to codes? Otherwise what do the codes mean? Appreciate any help


Your battery has nothing to do with these codes. Your vehicles computers have detected a malfunction or failure in the system. This triggers these codes and sets your check engine light. Below I have listed the code meanings and some repair solutions.

P1126 - Throttle Position (Narrow Range) Sensor Circuit Malfunction.

Power supply for the throttle control motor is provided to the ECM via throttle control motor relay. The throttle control motor relay is ON/OFF controlled by the ECM. When the ignition switch is turned ON, the ECM sends an ON signal to throttle control motor relay and battery voltage is provided to the ECM. When the ignition switch is turned OFF, the ECM sends an OFF signal to throttle control motor relay and battery voltage is not provided to the ECM.

Possible Causes For P1126:
- Harness or connectors (Throttle control motor relay circuit is open)
- Throttle control motor relay


P0325 - Knock Sensor Circuit Malfunction

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 Electronic Control Module (ECM).

Possible Causes For P0325:
- Knock sensor circuit short to ground.
- Knock sensor circuit short to power.
- Knock sensor circuit open.
- Damaged knock sensor.
- Damaged PCM or ECM

Possible Solutions:
- Repair or resecure harness or connector
- Replace knock sensor Bank 1 (Bank 1 if applicable)
- Replace PCM or ECM

The P0325 DTC is a very common problem with Nissan vehicles. On most Nissan vehicles the knock sensor is located on top of the engine block.

Knock sensor


Check knock sensor wiring and replace the knock sensor.

To find the knock sensor look at the top of the engine block below the intake manifold. There you should find the knock sensor wherethe throttle cables connect to the throtle body, reaching it from underneath, and bolted to the top of the motor , below comes a picture:
