Where is the throttle position sensor installed?
One side of a throttle shaft mount on a throttle body is operated by a throttle. Throttle position sensor, also known as throttle opening sensor or throttle switch, is a device for detecting engine state: 1, and throttle position sensor is also known as throttle opening sensor or throttle switch. Its main function is to detect whether the engine is in idle or load condition, acceleration or deceleration condition. 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. It has two contacts: a fully open contact and an idle 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 is in other positions, the idle contact opens to output voltage signals at different angles relative to the throttle, and the computer will identify the engine load according to the signal voltage value; 3. According to the change rate of signal voltage in a certain period of time, identify whether it is an acceleration condition or a deceleration condition. The computer corrects the fuel injection quantity or controls the fuel cut-off according to these working conditions.
