P2113: Throttle/Pedal Position Sensor "B" Minimum Stop Performance

Definition

The OBD2 code P2113 indicates that the throttle or pedal position sensor "B" is not reaching its minimum stop position as expected, which can affect engine performance and throttle response

Common causes

Faulty throttle body
Malfunctioning throttle position sensor (TPS)
Wiring issues or damaged connectors
Poor electrical connections
Faulty accelerator pedal position sensor
Vacuum leaks
Software issues or PCM problems
Carbon buildup in the throttle body

Common misdiagnoses

Throttle body issues
Accelerator pedal position sensor failure
Wiring or connector problems
Engine control module (ECM) failure
Vacuum leaks
Air intake issues
Fuel system problems
Transmission issues
Mass air flow sensor malfunction
Ignition system faults

Troubleshooting steps

1. Check for Additional Codes

Use an OBD-II scanner to check for any other trouble codes that may be present. Addressing any related codes can help in diagnosing the issue more effectively
2. Inspect Throttle Body
3. Check the throttle body for any signs of dirt, carbon buildup, or physical damage. Clean the throttle body if necessary, as buildup can affect its operation
4. Ensure that the throttle plate moves freely and is not sticking
5. Examine Throttle Position Sensor (TPS)
6. Inspect the throttle position sensor and its wiring for any signs of damage, corrosion, or loose connections
7. Test the TPS using a multimeter to ensure it is functioning within the manufacturer's specifications
8. Check Pedal Position Sensor
9. Inspect the accelerator pedal position sensor and its wiring for damage or poor connections
10. Test the pedal position sensor to ensure it is providing the correct voltage signals
11. Inspect Wiring and Connectors
12. Check all related wiring and connectors for signs of wear, corrosion, or damage. Repair or replace any faulty wiring or connectors
13. Perform a Throttle Body Relearn
14. After cleaning or replacing components, perform a throttle body relearn procedure. This can often be done using a scan tool or by following specific steps outlined in the vehicle's service manual
15. Check for Vacuum Leaks
16. Inspect the intake system for any vacuum leaks that could affect the throttle operation. Use a smoke machine or spray soapy water around the intake manifold and vacuum hoses to identify leaks
17. Inspect Engine Grounds
18. Ensure that all engine ground connections are clean and secure. Poor grounding can lead to erratic sensor readings
19. Test the Engine Control Module (ECM)
20. If all other components check out, the issue may lie with the ECM. Testing or reprogramming the ECM may be necessary, but this should be a last resort after all other possibilities have been ruled out
21. Consult Technical Service Bulletins (TSBs)
22. Check for any TSBs related to the specific make and model of the vehicle. Manufacturers may have issued updates or fixes for known issues. 1
23. Professional Diagnosis
24. If the problem persists after performing the above steps, consider seeking help from a professional mechanic or dealership for a more in-depth diagnosis. By following these troubleshooting steps, you can systematically identify and resolve the issue associated with the P2113 code
