What is the use of throttle position sensor?

The throttle position sensor is located next to the throttle and is the "personal" doctor of the throttle. Some childlike innocence will ask, "Can the throttle position sensor be unplugged? If not, I will pull it out and pretend. "

Throttle sensor efficacy

Throttle position sensor is one of the most important sensors in automobile electronic control system. It is installed on the throttle to check the change of throttle opening. It converts the change of throttle opening into an electrical signal and inputs it to ECU, which judges the working state of the engine according to the data signal of throttle position, and then the electronic computer adjusts the ignition advance angle and ignition timing according to this information.

Can the throttle position sensor be unplugged?

Can't! That will do some damage to the operation of the car. After the throttle position sensor is unplugged, it will be impossible to check the running state of the engine, and it will be difficult for the on-board computer to manipulate and adjust the ignition advance angle, which will also endanger the waiting state of the car. After unplugging the throttle position sensor, some cars will enter the safe mode, and the computer is not allowed to drive too fast. Faster speed will only be maintained at 40 kilometers, and some will increase fuel consumption. If the throttle position sensor is faulty or damaged, it is best to remove and replace it immediately.

Damage symptom of throttle position sensor

If the throttle position sensor is damaged, the car will have abnormal waiting speed (such as too high or too low waiting speed, idling jitter and easy flameout) or abnormal engine acceleration (such as engine jitter and slow response during acceleration), and may also cause intermittent vibration of the engine during operation.
