How does the TPS monitor the throttle position?
The TPS monitors the position of the throttle valve, which regulates how much air is supplied to the engine. Your gas pedal is attached to the the throttle valve (either electronically or mechanically) — as you press the pedal farther in, the valve opens more.
What is the adjustment procedure for the TPS?
SERVICE INFORMATION The adjustment procedure for the throttle position sensor (TPS) has been revised and standardized for all the Applied Vehicles. • The TPS contains a closed throttle position switch (CTPS) and a variable output throttle position sensor.
What are the symptoms of a bad TPS?
Below are common symptoms of a faulty TPS. In most of the cases, all of these symptoms will show together making it easier to detect the faulty component. Jerking or bucking of the vehicle is the most common symptom of a bad TPS.
How does the TPS work on a Nissan Leaf?
• The TPS contains a closed throttle position switch (CTPS) and a variable output throttle position sensor. • This procedure uses the closed throttle position switch (CTPS) status (ON or OFF) instead of the throttle position sensor (variable output voltage) to adjust the TPS.

Can a bad check engine light be a bad TPS?
The check engine light will randomly turn on and off even if the car is running smoothly without any jerks and stalling. This is often the first ever symptom of a bad TPS. Using a code reader, you should be able to confirm whether a faulty TPS is the culprit or a different component.
What do you need to know about replacing TPS?
Replacing the TPS will include clearing relevant fault codes, and may require software reprogramming of the new TPS module to match other engine management software. This is all best left to a professional mechanic who can provide you with a diagnosis, and then install the correct replacement part.
How is the TPS signal used in the engine?
The TPS signal is continually measured and combined many times per second with other data such as air temperature, engine RPM, air mass flow, and how quickly the throttle position changes. The collected data determines precisely how much fuel to inject into the engine at any given moment.
