How does the throttle position sensor work on a Montero?
The throttle position sensor on your 3.0L Montero needs power (and Ground) to function. So, in this test step we’ll check that the wire that connects to TPS connector pin #4 has 5 Volts DC with the Key in the On position. Alright, these are the test steps:
How does throttle position sensor work on 1997 Nissan Maxima?
Today we’re replacing, and adjusting, a throttle position sensor. The sensor detects the opening and closing of the throttle valve and feeds that info to the vehicle’s computer. This was performed on a 1997 Nissan Maxima. Check with your vehicle’s repair manual for testing parameters.
How to test the throttle position sensor ( TPS )?
So far so good since this tells you that the throttle position sensor (TPS) is getting power from the powertrain control module (PCM). The next and last test, is to make sure that the throttle position sensor is getting Ground (from the PCM too). For this test, go to: TEST 3: Verifying Throttle Position Sensor Has Ground.
Why is my throttle position sensor not working?
The TP sensor is not providing a varying voltage signal when manually opening the throttle plate. The TP sensor is being fed 5 Volts DC. The TP sensor is being fed Ground. Therefore, you can conclude that the throttle position sensor is bad and needs to be replaced (and that this will solve the TP sensor code lighting up the check engine light).

How to test the throttle position sensor ( 3.0L )?
The next and last test, is to make sure that the throttle position sensor is getting Ground (from the PCM too). For this test, go to: TEST 3: Verifying Throttle Position Sensor Has Ground. CASE 2: Your multimeter DID NOT register 4.5 to 5 Volts. Double check all of your connections and repeat the test.
Can a bad throttle position sensor cause stalling?
Similarly, if your engine struggles to idle efficiently, it could also be a result of a damaged throttle position sensor. Stalling, surging, or hesitating while idling all can be caused by this unassuming sensor. The best way to determine if these issues are caused by your throttle position sensor is to go to the source.
