Nissan Knock Sensor Problems

Need help deciphering error codes related to the knock sensor? Is the timing off on your Nissan causing it to run irregular? The most common signs of Nissan knock sensor problems are flashing of the check engine light on the dashboard, thumping noises from the engine, a misfire when the Nissan is started, burning smells emitted by the exhaust, acceleration problems and a bad fuel economy. If you need assistance to diagnose Nissan knock sensor problems you should ask Experts.

Listed below are questions answered by Experts on how to fix or replace a Nissan knock sensor.

What does code P0315 on a 1998 Nissan Maxima indicate and how to inspect the component?

P0315 is a hard code knock sensor and indicates that the sensor has failed. To replace the sensor, use a quarter inch swivel and extension to loosen the 12 mm bolt.

To perform a component check, first disconnect the knock sensor harness connector and check the resistance between terminal 2 and the ground. The resistance should fall between 500-600 kΩ at 250C. You will need to use an ohmmeter that can measure more than 10MΩ. When replacing the knock sensor make sure that you are using new knock sensors that have not been dropped or damaged.

Can a bad Nissan knock sensor cause the timing to be off and throw P0325 and P0335 codes?

A bad Nissan knock sensor will not affect the crank sensor code. If you are getting a P0335 code after replacing the crank sensor, it indicates an issue with the wiring from the sensor to the ECM. Also since the wiring is shielded, if there is some problem with the shield, it could be picking up a signal from somewhere in the electrical system.

What does a P0300 code on a 2001 Nissan Xterra indicate?

Code P0300 usually occurs when there is a misfire, which could be caused by a bad fuel injector. Try cleaning the fuel injectors with an injector cleaner machine. If this doesn’t work, it could be because of any of the following reasons; a bad injector, an improper spark plug, insufficient compression, incorrect fuel pressure, the injector circuit is open or has shorted, an intake air leak, the ignition secondary circuit is open or has shorted, lack of fuel, drive plate or flywheel issues, a heated oxygen sensor or an incorrect distributor rotor.

Where is the knock sensor located on a 1998 Nissan Pathfinder?

The knock sensor is located on top of the engine block under the intake manifold. To access the knock senor you will need to remove the intake plenum, injectors and intake manifold.

What does code P1444 indicate on a 1998 Nissan Pathfinder?

Code P1444 indicates a problem with the Evap Purge Volume control solenoid. This is located on top of the intake plenum by the throttle cables. Check if the solenoid is working properly and if it is not, it will need replaced.

Failure to detect Nissan knock sensor problems can result in serious damage to the engine. To learn how to identify symptoms and repair a malfunctioning Nissan knock sensor it is highly recommended to contact an Expert.
