Choose Your Throttle Position Sensor (TPS) Help Topic Below
So, The throttle position sensor (TPS) monitors; how far open the throttle valve (or blade) is open. Consequently, Determined by; how far down the accelerator pedal has been pushed. Also, The throttle position controls the amount of air; that flows into an engine’s intake manifold. So, The wider it is open; the more air is able to flow in. In contrast, The less that it is open; less air is able to flow in.
So, The position of the throttle; and how quickly it’s opening and closing is transmitted to the (ECM). Consequently, The computer uses that information to decide; how much fuel is injected into the engine and the spark timing.
What can happen when it malfunctions:
- It can trigger a “check engine” warning light
- It causes the engine to idle roughly; surge, hesitate or stall
As a result, The engine control module (ECM); doesn’t know where the throttle position is. Therefore, It can not correctly; set the fuel mixture or ignition timing.
Symptoms of a bad (TPS):
- Check engine light is on.
- Engine has little or no acceleration.
- Car bucks or jerks violently.
- Engine surges and stalls out.
- Engine starts and dies immediately.
- Poor fuel economy.
- Car goes into limp-home mode.
Replacing it can be straightforward; depending on the model; but the hardest part of the procedure is the diagnosis. As a result, You will need to have the proper diagnostic equipment.
So, It is a small sensor; that’s about the size of your key fob. Also, It has an electrical connector attached to it; that normally houses three wires. On most engines, there are two smaller screws; that secure it to the throttle body.
