How to detect the automotive throttle position sensor, what will be the effect if the sensor is broken?

What will be the impact if the automotive throttle position sensor is broken

1. The idling speed of the car is unstable, because the sensor detects the real-time condition of the engine through two contacts. Once a problem occurs, it will be very unstable when idling.
2. The car cannot be started, and even if it is started, it will often turn off.
3. If the automotive throttle position sensor is broken, the intake system will be affected.
4. Insufficient intake air in the cylinder, insufficient combustion, poor mixing ratio, weak acceleration, and shaking.
5. The fuel consumption of the vehicle increases, the idle speed is unstable, and the engine work decreases.
6. The air flow meter and the throttle valve sensor are the main control signals used to control the fuel injection amount. Not even a single car can deliver.
7. Weak acceleration, panting when driving, and unstable idling.

How to detect automotive throttle position sensor?

Throttle valve failure.
The throttle body position sensor can be used to detect the opening of the throttle body to determine the working condition and load of the engine, and can provide the throttle body opening signal on the automatic transmission vehicle. The throttle body position sensor is a friction part and a wearing part, and the following faults will occur when the sensor itself or the circuit is bad:
When the vehicle is running, the engine is easy to stall, and it is difficult to start the car or start the car, which is the most common fault of the throttle body position sensor. During engine operation, the idle speed is unstable, there is intermittent jitter during acceleration, the response is slow, the speed is high and low, and occasionally short circuit or open circuit is caused, which is also caused by the fault of the throttle body position sensor.

Throttle valve use precautions
After cleaning the throttle valve, reset the throttle valve opening, otherwise the car computer has memorized the opening degree when there is carbon deposition. Even worse before cleaning.
There are different ways to match the throttle valve according to different models. Generally, the matching only needs to disconnect the power storage. Note that it is best to check the matching method of the model before matching. Some models cannot be powered off, otherwise the anti-theft protection will be triggered. Trouble, these cars need computer matching. There are also some cars that only need to open the key door and will automatically match, after the matching is completed, it will not have any effect on the car.
