Diagram available for 01 Nissan Xterra Knock Sensor location?

go here: http://parts.nissanusa.com/nissanparts/index.cfm?bodyColor=&trimColor=&BODY=W&ENGINE=VG33E&EMISSION=GXE&TRIMLVL=GXE&TRANS=AT&action=replacement&groupid=D&sectionid=226&partcode=22060P&jointvehid=10541&makeid=25&siteid=14&illust_seq=01

This will show you the diagram of where it is located...auto parts stores carry this part too so don't think that the price you see there is final.
Hope this helps you

Hope this helps!!!

Hello the sensor is located under your intake manifold you will need to remove the intake manifold to gain access to it here is photos of what and where your looking for this

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.

Thank you fo using Fixya

For your 01 Nissan xterra V6 3.3L. The sensor is located underneath the air intake manifold on top of the engine block.

All the best!

Here the answer, dont flood!!!

Good luck.

Your knock sensor is located undernesth the air intake manifold on top of the engine block. This goes for 2000-2004 xterra V6 3.3L models.

HI, click the link below to be directed to a full diagram that will show you the actual location of the sensor. 718 will be the actual sensor to extract and 739 is the mounting screw for the KS.

Hope these help mate

It's the valley of the engine underneath the intake manifold. It's about an $800 job because the top of the engine has to come off. However, unless you have a supercharged xterra it shouldn't effect performance. Also, the knock sensor will not trip the check engine light, as it does not indicate a primary problem, so if your light is on you should have another code that should be fixed first.
