The TPS sensor is a potentiometer, providing a variable. Read more: How the Throttle Position Sensor Works. The TPS sensor is usually located on the throttle valve spindle so that it can directly monitor its position. Wait 7 seconds and fully press the accelerator pedal and hold for approximately 20 seconds until the check engine light stops blinking and stays on. The throttle position sensor (TPS) is used to monitor the position of the throttle valve in an internal combustion engine. Immediately after the 3 seconds, the accelerator pedal must be pressed and released 5 times within 5 seconds. Turn the ignition switch on and wait 3 seconds. How do you reset throttle position sensor?
Driving with a bad throttle position sensor may also cause problems in other related systems in your car, which will mean additional repair bills. If you have a bad throttle position sensor, your car will not perform well or safely. Completely replacing your sensor may be the best way to avoid future issues, but some issues can be easily fixed by reprogramming or repairing your sensor.Īdditionally, can you drive with a bad throttle position sensor? One of the leads is connected directly to the computer's 5-volt voltage supply, and the other lead connects to the ground circuit. Most have extra pins for extra functionality, such as cruise control traction and electronic stability control.
The TPS can also send bad input that ends up stalling the engine at any time.Īdditionally, can you fix a throttle position sensor? Repair, Reprogram, or Replace Your Sensor Once you've gone through the symptoms of a bad throttle position sensor, it's time to find a solution. Throttle position sensors indicate the engine's throttle angle to the engine control module. Similarly, it is asked, what happens when throttle position sensor is bad?Įngine won't idle smoothly, idles too slowly, or stalls If you start to experience engine misfires, stalling, or rough idling when the car is stopped, it can also be a warning sign of a failing TPS.
#Throttle position sensor driver
This information contains the actions of the driver such as accelerating, power steering and so forth. Basically, this sensor is connected to a computer inside the vehicle which shares information sent by the driver. Correcting the TPS then produced a correct idle, and no code. The throttle position sensor is what monitors the throttle position from the shaft. If the TPS is not adjusted correctly as evidenced by a 500rpm idle, and hesitation with initial acceleration, unplugging the TPS connector should then cause a correct idle, and a normal acceleration.
