Intake Air Temperature Sensor 2 Circuit Bank 2

Where it lives

For P00A5, the circuit described runs through the sensor. The description of P00A5 puts it on bank 2.

Check these first

• A failed intake air temperature sensor 2 on bank 2
• An open or short in the sensor 2 signal wire
• Corrosion at the sensor 2 connector
• A bad ground shared by the sensor 2 circuit
• A faulty ECM input

What to do next

1. Read the sensor 2 value on bank 2 and compare to ambient
2. Inspect the sensor 2 connector and wiring for corrosion
3. Test the sensor 2 signal circuit for opens and shorts
4. Check the sensor resistance against a temperature chart
5. Replace the intake air temperature sensor 2 if it reads out of range
6. Clear the code and retest
