P00ADIntake Air Temperature Sensor 1 Circuit High Bank 2
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Needs a drive cycle to confirm a fix
- How the car detects it
- 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 P00AD, the sensor signal is above its valid range. With the usual voltage-type NTC sensor this means an open circuit or a short to the reference voltage, and the control module reads an extremely low temperature; with sensors that have a frequency output, a high signal corresponds to an extremely high temperature. Bank 2 codes occur only on engines with two separate intake or charge-air paths, one per cylinder bank.
- What you may notice
- Check engine light on
- Usually no noticeable symptoms
- Slightly changed power or knock control with an implausible reading
- Likely causes

- RareEngine control module faulty
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
- Repair
- Easy · Often possible to do yourself.Typical cost: €40 – €250
