The main issue with a throttle position sensor is its tendency to eventually fail. Sensors in vehicles are susceptible to failure due to their nature as basic electrical components that can deteriorate over time. When your throttle position sensor is failing, you may experience unresponsiveness when pressing the gas pedal, as well as rough idling since the throttle body may not be functioning correctly. This sensor plays a critical role in receiving input from the gas pedal and regulating the opening and closing of the throttle body.
Numerous indicators suggest a faulty throttle sensor in a Civic, such as decreased power during acceleration, erratic or sluggish idling, stalling, difficulty shifting gears, and the illumination of the check engine warning light.
