P00AD

DTC P00AD, sometimes indicated as P00AD00 is an OBD diagnostic trouble code indicating a generic fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the air/fuel mixture causing intake air temperature sensor 1 circuit high bank 2.

The intake air temperature sensor measures the temperature of the air entering the engine. This information is used by the engine control module (ECM) to calculate the correct amount of fuel to inject.
If the intake air temperature sensor is reporting a high temperature, it may be caused by a problem with the sensor itself, a problem with the wiring or connector, or a problem with the ECM.
If the intake air temperature sensor is reporting a high temperature, the first thing to check is the condition of the sensor. If the sensor is dirty or damaged, it will need to be replaced.
If the sensor is okay, the next thing to check is the wiring and connector. If the wiring or connector is damaged or corroded, it will need to be replaced.
If the wiring and connector are okay, the next thing to check is the ECM. If the ECM is defective, it will need to be replaced.
