Guide To P2139 OBD Error Code Solutions

The sensors in question ie tha Throttle Position Sensor and the Pedal Position sensors are located in the intake manifold and the Accelerator Pedal Assembly respectively. This code is indicative of an improper voltage correlation present between both these sensors. This results in the throttle plate becoming unable to open and close efficiently. Signals that are sent from both these sensors to the Electronic Control Unit of your vehicle helps the ECU to determine how much the throttle plate should be opened or closed. A malfunction of this signal, can result in the P2139 code to be set.

What causes this problem with the Throttle/Pedal Pos Sensor Voltage Correlation DTC?

• Fault in the Accelerator Pedal Position Sensor
• Harness of the Accelerator Pedal Position Sensor is open or shorted
• Poor electrical connection in the circuit of the Accelerator Pedal Position Sensor
• Defective Electric Throttle Control Actuator
• Failure of the electronic throttle body
• Failure of the Pedal position sensor
• Issue with the throttle position sensor
• Wiring harness if open or shorted
• Low electrical connection
