The P2133: Throttle/Pedal Position Sensor/Switch ‘F’ Circuit High refers to a condition where the throttle or pedal position sensor ‘F’ is sending a higher-than-expected voltage or signal. This could be due to a faulty sensor, wiring issues, or other electrical faults.
P2133 – Quick Overview
| Code | Information |
|---|---|
| Meaning | P2133: Throttle/Pedal Position Sensor/Switch ‘F’ Circuit High |
| Is it serious? | Yes, it can affect throttle control and cause drivability issues. |
| Possible causes | – High voltage or signal from throttle/pedal position sensor ‘F’ – Faulty sensor – Wiring issues |
| How to diagnose? | – Measure voltage or signal from the sensor – Test the sensor for faults – Inspect wiring and connections |
P2133 Meaning
The P2133 code indicates that the throttle or pedal position sensor ‘F’ is sending a voltage or signal that is too high. This could cause issues with throttle control, including sudden or unintended acceleration, or poor throttle response. The problem might be due to a malfunctioning sensor, wiring problems, or faulty connections.
Step-by-step diagnostic guide
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to check for other related codes that may provide additional context for the issue. | OBD-II Scanner |
| Inspect Sensor Wiring | Visually inspect the wiring and connectors connected to throttle/pedal position sensor ‘F’ for signs of damage, loose connections, or corrosion. | Flashlight, Multimeter |
| Measure Voltage or Signal | Use a multimeter to measure the voltage or signal output from the throttle/pedal position sensor ‘F’. Compare the readings with manufacturer specifications. | Multimeter |
| Test Sensor for Faults | Use a diagnostic tool to check the throttle/pedal position sensor ‘F’ for internal faults or abnormal readings. | Diagnostic Tool, Multimeter |
| Inspect Wiring for Shorts or Damage | Check for shorts, open circuits, or physical damage in the wiring leading to the sensor. Repair or replace damaged wiring as necessary. | Multimeter, Wiring Diagram |
| Clear the Code and Test Drive | After repairs or adjustments, clear the code with an OBD-II scanner and take the vehicle for a test drive to ensure the issue has been resolved. | OBD-II Scanner |
| Recheck for Codes | After the test drive, re-scan the vehicle to ensure the P2133 code has not returned. | OBD-II Scanner |
