Intake Air Temperature Sensor 1 Circuit Intermittent Bank 1

Where it lives

For P0114, the circuit described runs through the sensor. The description of P0114 puts it on bank 1.

Check these first

• A loose connector at intake air temperature sensor 1
• Chafed wiring on the sensor 1 circuit
• A failing sensor 1 element
• Water intrusion in the sensor 1 connector
• A poor ground for the sensor 1 circuit

What to do next

1. Wiggle test the sensor 1 harness on live data
2. Inspect the sensor 1 wiring for chafing
3. Check the connector for water intrusion
4. Replace intake air temperature sensor 1 if erratic
5. Clean the connector and ground
6. Clear the code and retest
