What happens if my throttle position sensor goes out?
A malfunctioning throttle position sensor will relay bad data to your car’s computer and usually result in poor fuel economy. Knowing the symptoms of a defective throttle position sensor can help you quickly diagnose the problem and make needed corrections.
Where is the throttle position sensor on a pathfinder?
As you’re probably already aware, the throttle position sensor (TPS) on your 3.3L equipped Nissan Pathfinder (Frontier, Xterra or QX4) is attached to the throttle body and its job is to measure throttle plate angle.
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.
What does the throttle position sensor on a Nissan do?
Since the throttle position sensor is one of several sensors that your Nissan’s fuel injection computer uses to calculate how much much fuel to inject, when it fails you’re going to see several symptoms. Check engine light (CEL) shining nice and bright.
Can a bad throttle position sensor cause a car to shake?
A bad throttle position sensor can cause other issues on your car if left unattended. That’s right! If the sensor is faulty, it will cause your car to shake heavily. Eventually, if this issue is left unattended it will put major stress on your motor and transmission mounts to the point where they will give out and will need replacement.

How does the TPS work on a Nissan Pathfinder?
In layman’s terms, this means that the TPS is tasked with the job of measuring how much you step on or step off the accelerator pedal as you’re driving the down the road. This throttle plate angle information is then sent to your Nissan’s fuel injection computer as a voltage DC signal. To give you a few more specifics:
