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 P00AA, this is the general circuit fault; low and high signals have their own codes. 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.
Low severity. Can I keep driving?Yes, you can normally keep driving and take it to a repair shop when convenient.
Bank 2 is the side without cylinder 1, so it only exists on V or boxer engines.
Symptoms
- Check engine light on
- Usually no noticeable symptoms
- Emissions test or readiness check may fail
Most likely causes
- Connector or wiring faulty
- Sensor faulty
- Supply or ground disturbed
- Engine control module faulty
What to check, in order
Start with the simplest. You can tick off each step.
Good to know
- Repair difficulty: easy
- It affects emissions.
What each character of P00AA means
- P: Powertrain: engine and transmission
- 0: Generic code: same on every make
- 0: Subsystem depends on the code range
- AA: Specific fault in that system
