What are the symptoms of a faulty throttle position sensor?
1 Answers
The symptoms of a faulty throttle position sensor include poor contact of the idle contact, no idle signal, engine stalling or unstable idle, poor contact of the no-load contact, no full-load signal input, which can result in the engine lacking high speed or experiencing acceleration difficulties. Additional information: The main causes of throttle position sensor failure are: 1. Corroded connectors, poor contact, low voltage, or no conduction, leading to engine stalling or difficulty starting. 2. Misaligned initial position, causing high or low output voltage, resulting in unstable idle speed, either too high or too low. 3. Coating failure, resistance changes causing inaccurate output voltage, leading to jerky starts and poor acceleration. 4. Excessive carbon buildup in the throttle, preventing proper closure, affecting output voltage and flow values, causing inaccurate air-fuel ratio and unstable idle speed.
