Fix poor throttle response, rough idle, sudden hesitation, or uneven acceleration with a throttle position sensor built to send accurate throttle angle signals to your engine computer.
The throttle position sensor (TPS) monitors the position of the throttle plate, which controls the airflow into the engine. By providing real-time feedback on how much the driver is pressing the gas pedal, the TPS helps the engine control unit (ECU) adjust the air-fuel mixture for optimal performance and efficiency.
A failing or malfunctioning Throttle Position Sensor (TPS) can manifest various symptoms, which may vary in severity. If you notice these situations, they may indicate a potential issue with the TPS:
Fixing a faulty TPS often involves either cleaning the sensor or replacing it, depending on the severity of the problem.
The diagnostic trouble code P0123, which indicates a high input in the throttle or pedal position sensor circuit A. Exploring the potential causes, symptoms, and troubleshooting steps, we aim to provide a comprehensive understanding of this issue.
Learn what P0121 means, whether you can keep driving, and how to distinguish wiring, throttle body, TPS, and APP sensor faults before choosing the correct repair.
The P0122 code indicates a faulty throttle position sensor (TPS) causing poor acceleration and idle issues. This guide details how to diagnose and replace the TPS to resolve the problem.
