I have a 2001 civic LX with a P0325 CEL. It says knock sensor circuit (bank 1). What does this mean and how do i correct it? I also have a P1298 code in for ELD voltage high. Both have been coming

sorry would a play with this to know for sure ,check the wiring plugs onto the sensors to make sure their not full of oil or corroded

P0325: Knock Sensor 1 Circuit Malfunction Bank 1 or 1 Sensor

- Knock sensor circuit short to ground
- Knock sensor circuit short to power
- Knock sensor circuit open
- Faulty knock sensor
- Faulty Engine Control Module (ECM)

Replacing the knock sensor usually takes care of the problem.

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 Engine Control Module (ECM).

P0325 knock sensor 1 circuit malfunction bank 1 or 1 sensor, the knock sensor should be check/replaced. You can buy Haynes Repair Manuals at Pepboys that will walk you throught the process step by step.
P0303 is a cylinder misfire in cylinder 3 which may mean it could either be the spark plug, coil or the injector.

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.

Code P0325 Knock sensor 1 circuit malfunction (bank 1 or single sensor)

On the Nissan that code means you have a short in the knock sensor circuit or you just need a new knock sensor.

P0340....Camshaft Position Sensor 'A' Circuit (Bank 1 or Single Sensor)
P0325....Knock Sensor 1 Circuit (Bank 1 or Single Sensor)if you have no spark it your cam sensor
