The P2115 OBD-II code indicates a problem with the throttle/pedal position sensor, specifically related to the minimum stop performance. This code is triggered when the engine control module (PCM) detects a malfunction in the electronic throttle control system (ETCS).
What Does the P2115 Code Mean?
The P2115 code signifies that the PCM has identified an issue with the throttle/pedal position sensor “D”. This sensor plays a critical role in determining how much power the engine should provide based on the driver’s input via the accelerator pedal.
What Causes the P2115 Code?
- Failure of the Accelerator Pedal Position (APP) assembly
- Powertrain Control Module (PCM) failure
- Throttle control motor failure
- Wiring issues related to the throttle control system
What Are the Symptoms of the P2115 Code?
- Decreased engine performance
- The engine may enter limp home mode, resulting in reduced power availability
How Serious Is the P2115 Code?
The P2115 code is considered urgent and indicates that immediate action is necessary. Ignoring this code can lead to severe vehicle damage or pose safety risks to the driver and passengers due to unexpected acceleration issues.
How to Diagnose the P2115 Code
Diagnosing the P2115 code involves using an OBD-II scanner to confirm the code, followed by a thorough inspection of the throttle control system. Mechanics will check for wiring issues, test the APP assembly, and evaluate the PCM functionality to pinpoint the exact cause of the fault.
Common Repairs for the P2115 Code
- Replacing the Accelerator Pedal Position (APP) assembly
- Repairing or replacing damaged wiring
- Replacing the throttle control motor
- Replacing the Powertrain Control Module (PCM) if it is determined to be faulty
How Much Does It Cost to Fix the P2115 Code?
The cost to fix the P2115 code can vary widely depending on the underlying cause. Simple wiring repairs may cost around $100-$200, while replacing the APP assembly or PCM could range from $300 to $800 or more, depending on the vehicle make and model.
Can I Fix the P2115 Code Myself?
While some DIY mechanics may be able to handle simple repairs like wiring fixes or part replacements, the complexity of the electronic throttle control system means that a complete diagnosis may require professional tools and expertise. It is advisable to consult a professional if you are unsure.
