Step-by-step diagnostic guide
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to see if there are other related codes that may provide additional context for the issue. | OBD-II Scanner |
| Inspect Throttle Sensor Wiring | Visually inspect the wiring and connectors connected to throttle position sensor ‘G’ for signs of damage, loose connections, or corrosion. | Flashlight, Multimeter |
| Check for Loose or Corroded Connections | Ensure all connections to the sensor are secure and free of corrosion. Clean or tighten connections as necessary. | Contact Cleaner, Flashlight |
| Test Sensor for Intermittent Faults | Use a multimeter or diagnostic tool to monitor the throttle position sensor ‘G’ for intermittent faults or fluctuations in signal. | Multimeter, Diagnostic Tool |
| Inspect Wiring for Damage | Check the wiring leading to the sensor for any signs of wear, tears, or damage that could cause intermittent faults. Repair or replace damaged wiring as needed. | Flashlight, Multimeter |
| Clear the Code and Test Drive | After making the necessary repairs or adjustments, clear the code with an OBD-II scanner and take the vehicle for a test drive to confirm the issue is resolved. | OBD-II Scanner |
| Recheck for Codes | After the test drive, re-scan the vehicle to ensure the P212E code has not returned. | OBD-II Scanner |
