What is P0632?

The Diagnostic Trouble Code (DTC) P0632 indicates a problem with the throttle position sensor (TPS) range or performance. This sensor is crucial for the engine's management system, as it relays the position of the throttle plate to the engine control module (ECM). When the ECM detects that the throttle position sensor is outside of the expected range, it triggers the P0632 code. This could affect various aspects of vehicle performance, including acceleration and fuel efficiency. In practical terms, if your vehicle, particularly models like the 2017 Ford F-150, 2016 Honda Accord, or 2018 Toyota Camry, is exhibiting this code, you may experience symptoms such as erratic engine performance, stalling, or even a decrease in fuel economy. The underlying issues could range from a faulty throttle position sensor to wiring problems or issues with the ECM itself. Addressing this code promptly is essential, as ignoring it could lead to more significant engine problems and costly repairs down the road.

System: P - Powertrain (Engine, Transmission, Emissions)

Symptoms

Common symptoms when P0632 is present:

  • Check engine light stays on constantly, indicating an issue that needs to be addressed.
  • Engine hesitates during acceleration, causing a feeling of power loss or jerking motion while driving.
  • Fuel economy decreased by 10-15%, noticeable during regular driving conditions.
  • Rough idling when stopped at a traffic light or in neutral, indicating irregular engine behavior.
  • Unresponsive throttle when pressing the accelerator, making it difficult to control the vehicle's speed.

Possible Causes

Most common causes of P0632 (ordered by frequency):

  1. Faulty throttle position sensor (TPS) - 60% likelihood. The sensor might be defective or sending incorrect signals to the ECM.
  2. Loose or damaged wiring/connectors - 20%. Corroded or broken wires can disrupt the connection between the TPS and ECM.
  3. ECM failure or issues - 10%. In some cases, the engine control module itself may have faults that affect sensor readings.
  4. Mechanical issues with the throttle body - 5%. A stuck throttle plate can lead to performance problems.
  5. Less common, faulty accelerator pedal position sensor - 5%. If this sensor malfunctions, it can impact throttle response.
