What does the throttle position sensor on a Montero tell you?
CASE 2: The voltage DID NOT increase/decrease as you manually opened/closed the throttle plate. This tells you that the throttle position sensor (TPS) on your Montero has a problem. Before condemning the TPS to the scrap heap, you need to make sure that it’s getting both power and Ground.
Where can I buy a throttle position sensor?
TEST 1: Testing The Throttle Position Sensor Voltage Signal. TEST 2: Verifying Throttle Position Sensor Has Power. TEST 3: Verifying Throttle Position Sensor Has Ground. Where To Buy Your Throttle Position Sensor And Save. You can find this tutorial in Spanish here: Cómo Probar El Sensor TPS (3.0L Mitsubishi Montero) (at: autotecnico-online.com ).
Where does the multimeter probe connect to the TP sensor?
With the red multimeter test lead probe the middle wire of the sensor’s connector. This is the wire that connects to TPS pin #3 in the illustration above. Connect the black multimeter test lead on the battery negative (-) terminal. Have your helper turn the key On, but don’t start the engine (this will power up the TP sensor).
What should my multimeter read when I open the throttle?
As the throttle opens, the voltage numbers will increase. This increase in voltage should be smooth and without any gaps or skips. Once the throttle is wide open, your multimeter should read somewhere between 3.5 to 4.5 Volts DC. Now, slowly close the throttle.

How to test the throttle position sensor ( TPS )?
This tells you that the throttle position sensor (TPS) on your Montero has a problem. Before condemning the TPS to the scrap heap, you need to make sure that it’s getting both power and Ground. To check for power, go to: TEST 2: Verifying Throttle Position Sensor Has Power. CASE 3: The multimeter DID NOT register any voltage.

Is there a way to reset the throttle body?
This method is almost foolproof as long as all ECU control parameters are within their normal ranges. Resetting The Throttle Body Calibration (this step is conditional) A Rough Idle or a SES can sometimes be caused by a change in the throttle body position sensor calibration.
