When do you need to replace the throttle position sensor?
As soon as you see a mix of these throttle position sensor symptoms, you should test the TPS and if it isn’t functioning properly, it needs to be replaced.

How does acceleration affect the gear transmission system?
The issues with acceleration can lead to gear transmission problems as the ECM doesn’t get the correct information about the acceleration. This leads to incorrect shift points which can cause both early or delayed shifts.
How is the throttle connected to the accelerator?
In the old days, there used to be a cable that was connected from the throttle to the accelerator. But now in the technological age, the car’s computer controls when the throttle opens and closes by the feedback it gets about the acceleration of the vehicle.

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 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.
What causes idle surges on a car ECM?
Idle surging can be caused due to other issues in the car, but if it happens in conjunction with other throttle position sensor symptoms, the culprit is often the TPS. At idle, the ECM will not get the correct information and the throttle will variate randomly causing idle surges.
What does it mean when your car throttles up while driving?
In these cases, the TPS isn’t providing the right input, the onboard computer cannot direct the engine to work properly. When the car accelerates while driving, it usually means the butterfly valve inside the throttle has closed up and pops open suddenly when the driver presses on the accelerator.

How does the TPS work to determine throttle position?
In some cases, the TPS uses what’s known as the Hall Effect to do its job, which involves magnetic fields that shift as the throttle opens and closes. The sensor reads those changes and communicates with the ECM to determine the exact throttle position.
When to move throttle control to slow or fast?
Move the application throttle control to the slow position, then to fast. Check the engine control to assure it stops against the high idle RPM stop bracket. NOTE: When the application throttle control lever is in the slow position the engine governor spring must be free of tension or pushing pressure. A non- free spring can affect the RPM.

What does the throttle position sensor ( TPS ) do?
The throttle position sensor (TPS) is part of your vehicle’s fuel management system and helps ensure that the correct mixture of air and fuel is delivered to your engine. The TPS provides the most direct signal to the fuel injection system of what power demands are being made by the engine. The TPS signal is continually measured…
