Intake air temperature sensor 1 for bank 2 measures the intake air temperature in the second intake path, typically near the air filter or in the air flow meter of that bank, on engines with two separate intake paths. For P00AE, the signal jumps faster than a real temperature can change, which typically points to a loose contact. No manufacturer description naming this exact code was found. Bank 2 codes occur only on engines with two separate intake or charge-air paths, one per cylinder bank.
Likely causes
Loose contact or wire broken by movement
Sensor failing intermittently
Interference on the signal wire
Symptoms
- Check engine light on
- Usually no noticeable symptoms
- Emissions test or readiness check may fail
