ok on a 2.4l on the black/green and white wires use ohm meter and there is no specific spec for that engine just make sure the the resistance changes and there is no dead spots. for the 3.0l black and white wires specs are 1.0-9.0k ohms im guessing the specs are the same either engine. close to full open

SOURCE: how to install a throttle position sensor NISSAN

First off I wasn't sure as to which engine you had in your vehicle as there is a 2.4 or a 3.3 liter engine for your vehicle for that year. I gave you some details on the 3.3 liter. I don't want to sound negative but Nissan's are basically dependant on its sensors which in turn send signals to the ECM which makes all of the adjustments as to how everything runs. If you do not have the proper equipment for diagnostic procedures it is difficult to get it correct but can be done. Even after you set the throttle position sensor (TPS) you need to reset the TPS idle position memory and then check the timing/idle mixture ratio and make any adjustments there if needed. I can do my best to try and walk you through it with details directly from the factory service manual and even can make you up a PDF of it if you want with ways to go around not having the diagnostic equipment. Also write if you have the 2.4 because the little bit of information I gave you below is only for the 3.3 liter engine. Again I'm not trying to sound negative to you and I believe I can walk you through it but it's not like just pulling a part & replacing it when it comes to your vehicle in order to get it done correctly.

My car keep stopping itook it to a mechanic shop to be put on the machine it read the throttle position sensor is killing the mechanic say the car donot have a throttle position do i have to bring the car...

No, actually I would find a different Mechanic. 2000 and newer the TPS, Throttle Position Sensor, is pretty much standard to control idle RPM. Even in Fuel injection, it is just located on an Air control valve instead of a Carburetor.

I have a 1994 nissian altima it has a low idle and shakes but it runs good how could i go about finding out the problem?

It sounds like you have a faulty TPS (throttle position sensor) it is an easy fix, and it is located on the throttle body. Just follow the air intake hose back from the air intake box, when it reaches the throttle body, you will see the TPS sensor. It is held on by 2 screws and will have a plug in.

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.

Our 2002 xterra idles between 1500 and 2000, and it's horrible on gas mileage

U might want to check the TPS (Throttle Position Sensor) I am actually changing mine tomorrow because my throttle is surging. It mightjust need adjusted or you might have to get a new 1. I suggest if you go to get a new 1 check Ebay first :)
