Intake Air Temperature Sensor 1 Circuit Low Bank 1

Where it lives

For P0112, the circuit described runs through the sensor. The description of P0112 puts it on bank 1.

Check these first

• A short to ground on the sensor 1 circuit
• A failed intake air temperature sensor 1
• A corroded sensor 1 connector
• An air duct leak on bank 1
• A faulty ECM input for sensor 1

What to do next

1. Inspect the sensor 1 wiring for a short to ground
2. Test the sensor 1 resistance against spec
3. Check the air intake duct for leaks
4. Replace intake air temperature sensor 1
5. Verify the ECM if the reading stays low
6. Clear the code and retest
