What is the method for measuring the throttle position sensor?
1 Answers
Measuring the throttle position sensor involves the following steps: 1. Check the supply voltage by unplugging the connector from the throttle position sensor, turning on the ignition, and measuring the voltage between VCC and the idle contact, as well as between VCC and the wide-open throttle contact. 2. Check the resistance by unplugging the throttle potentiometer connector and measuring the resistance between VCC and the idle contact, as well as between VCC and VTH. Symptoms of a faulty throttle position sensor include: 1. Idle speed being too high or too low; 2. Unstable idle speed or the engine stalling easily at idle; 3. Engine shaking during acceleration; 4. Delayed response to acceleration; 5. Intermittent engine shaking during operation.
