I'm trying to find this as well...
I've been told its on the back of the engine above the oil filter, however, I cannot locate it...
I have the replacement sensor from Autozone in my hand ($104.XX) yet cannot find where it is supposed to go.  There is a random bolt above a freeze plug, I'm wondering if it is supposed to be in that location.  Not sure that this is even the original motor... eek!

Where is the knock sensor located on 1997 Toyota Tercel


Hello,

The knock sensor is usually located in the side of your engine block just under the exhaust manifold. If your standing in front of the car (Since Its Front Wheel Drive) It should be almost in the center directly in front of you.

I have a 2004 pilot, VTS4 and engine light came on. i have a p0325 knock sensor circ. bank A. just replace the sensor?? also i can seem to find any diagrams. any help appreciated!!!


It does sound like the sensor may be bad, but you also need to check the wiring.
This information comes from:

http://www.obd-codes.com/p0325

P0325 OBD-II Trouble Code Technical Description

Knock Sensor Circuit Malfunction
What does that mean?

A knock sensor tells the engine computer when one or more of your engine's cylinders are "knocking", that is, exploding the air/fuel mixture in a way that delivers less power and can be damaging to the engine if prolonged. The computer uses this information to tune the engine so that it doesn't knock. If your knock sensor wasn't operating properly, so that it was always indicating a knock, the engine computer's response may have been to change the ignition timing on your engine. Knock sensors generally bolt into or thread into the engine block. This P0325 code may show up intermittently or the Service Engine light may be lit constantly. Other knock sensor related DTC codes include P0330.
FB.init("dd7d9e9681341cde77587bc6a2029f6f"); OBD-Codes.com on Facebook Symptoms

You may notice drivability problems including a lack of power and perhaps some hesitation. There may also be other symptoms.
Causes

A code P0325 most likely means one or more of the following has happened:

Possible Solutions
  • Check the resistance of the knock sensor (compare it to factory specs)
  • Check for broken/frayed wires leading to the sensor
  • Replace the knock sensor

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.

P0325 how do i fix it? tnx.


A P0325 refers to the knock sensor electrical circuit, not the sensor itself! So check all wiring & connectors leading to the sensor, back to the PCM. Good luck, I found a good P0325 article HERE
