The OBD-II code P2117 indicates a problem with the throttle/pedal position sensor “F” in your vehicle’s electronic throttle control system (ETCS). This code is triggered when the engine control module (PCM) detects that the minimum stop performance of the throttle or pedal position sensor is not functioning correctly.
What Does the P2117 Code Mean?
The P2117 code specifically refers to decreased engine performance due to a malfunction in the throttle/pedal position sensor “F.” When this code is set, it means that the PCM has detected an issue with the minimum stop position of the sensor, which can affect how the throttle valve opens in response to the driver’s acceleration request.
What Causes the P2117 Code?
Several factors can trigger the P2117 code, including:
- Accelerator Pedal Position (APP) assembly failure
- Powertrain Control Module (PCM) failure
- Throttle control motor failure
- Wiring issues
What Are the Symptoms of the P2117 Code?
When you encounter the P2117 code, you may experience the following symptoms:
