Common Causes of P0113
- Faulty IAT sensor
- Damaged wiring or connectors
- Contamination on the sensor
- ECM malfunction
- Extreme environmental conditions
Diagnosing the Issue
- Perform a visual inspection of the sensor and wiring
- Use a multimeter to test sensor resistance
- Employ an OBD-II scanner for live data analysis
- Check for consistent voltage output from the sensor
Fixing the P0113 Error
Depending on your diagnosis, you may need to:
- Replace the IAT sensor
- Repair or replace damaged wiring
- Clean the sensor if contaminated
- Update or replace the ECM in rare cases
