What happens when the throttle position sensor malfunctions?
When the throttle position sensor malfunctions, the engine control unit has no information about the gas pedal, and the throttle plate is not utilized. As a result, your vehicle will not get the right amount of air into the engine, and your engine will lose power and run very poorly.
How much does it cost to replace a throttle position sensor?
Jaguar S-Type Throttle Position Sensor (TPS) Replacement costs $461 on average. What is the Throttle Position Sensor all about? For a car to run smoothly, it needs the proper mixture of air and fuel. The amount of air in the engine is controlled by the air intake system.
What does the throttle body do in a car?
A throttle body is part of the air intake system that helps control the amount of air that gets into the engine. The throttle body has a throttle plate. If the plate is closed, it prevents the air from getting into the engine.
What causes engine to jerk under light acceleration?
It is not a coil or air mass meter because you have no fault code for it. Maybe a air leak on the inlet manifold but this would show up as running lean. There is no spark plug leads. I would change the fuel filter, it takes very low/high pressure to bring a fault code up for this.
Can a bad throttle position sensor cause stalling?
Similarly, if your engine struggles to idle efficiently, it could also be a result of a damaged throttle position sensor. Stalling, surging, or hesitating while idling all can be caused by this unassuming sensor. The best way to determine if these issues are caused by your throttle position sensor is to go to the source.

How do you check the resistance of a throttle valve?
