Humidity Sensor Circuit Range/Performance

Where it lives

For P00F3, the description names the sensor as the part involved.

Check these first

• A failed humidity sensor
• An open or short in the sensor signal circuit
• Corrosion in the sensor connector
• A fault in the module reading the sensor

What to do next

1. Inspect the humidity sensor connector and wiring
2. Check the sensor signal and ground circuits for opens or shorts
3. Compare the sensor reading against a known-good value
4. Check for water intrusion at the sensor
5. Replace the humidity sensor if the circuit tests good
6. Clear the code and retest
