How does the throttle position sensor work on a Nissan Pathfinder?
To give you a few more specifics: The throttle plate opens and the TP sensor measures how much and relays this to the PCM. The fuel injection computer injects more fuel. The throttle plate closes and the TP sensor measures how much and relays this to the PCM. The fuel injection computer injects less fuel.
Why does my Nissan Pathfinder fail the emissions test?
Check engine light (CEL) shining nice and bright. P0120: TP Sensor A Circuit Malfunction. Your Nissan Pathfinder (Xterra, Frontier) fails the state mandated emissions test. Bad gas mileage. Hard start and/or extended cranking time (after shut off). Black smoke coming out of the tailpipe. Hesitation when accelerating your Pathfinder down the road.
How to troubleshoot the throttle position sensor ( TPS )?
Testing the throttle position sensor (TPS) to see if it has failed and causing a TPS diagnostic trouble code (DTC) is not hard. In this tutorial, I’m gonna’ show you how to troubleshoot the throttle position sensor (TPS) on your Nissan 3.3L Pathfinder (Frontier, XTerra or QX4), with a multimeter and in a step-by-step way.
