The position of Cruze throttle position sensor 1-2 is unreasonable.

The position of Cruze throttle sensor 1-2 is unreasonable, which is generally caused by the throttle. If the original throttle is replaced, it is recommended to check whether the plug line from the vehicle throttle plug to the engine computer is damaged. Check the signal voltage of throttle position sensor with computer. In this case, the throttle valve can be cleaned first and then reset. If it doesn't work, you must replace the throttle valve.

Role of throttle position sensor:

1. Throttle position sensor, also known as throttle opening sensor or throttle switch, is mainly used to detect whether the engine is idling or loading, accelerating or decelerating. It is essentially a variable resistor and several switches installed on the throttle body.

2. The rotating shaft of the resistor is connected with the throttle valve, and it has two contacts: a fully open contact and an idling contact. When the throttle valve is in the idle position, the idle contact is closed and the idle working condition signal is output to the computer; When the throttle valve is in other positions, the idle contact is opened, and voltage signals with different angles relative to the throttle valve are output, and the computer identifies the engine load according to the signal voltage value; According to the change rate of signal voltage in a certain period of time, whether it is an acceleration state or a deceleration state is identified. According to these working conditions, the computer corrects the fuel injection quantity or controls the fuel cut-off. (Photo/Text/Photo: Li Linwei) @20 19
