Intake Air Temperature Sensor 1 Circuit Intermittent Bank 2

Where it lives

For P00AE, the circuit described runs through the sensor. The description of P00AE puts it on bank 2.

Check these first

• A chafed bank 2 sensor 1 wire that opens and closes
• Corroded pins in the bank 2 sensor 1 connector
• A failing intake air temperature sensor 1 on bank 2
• A loose ground on the bank 2 sensor 1 circuit
• A faulty ECM input

What to do next

1. Wiggle the bank 2 sensor 1 harness while watching the data
2. Inspect the bank 2 connector for corrosion
3. Check the bank 2 sensor 1 ground for looseness
4. Replace the intake air temperature sensor 1 if the reading jumps on its own
5. Check the ECM input if the fault follows no wiring
6. Clear the code and retest
