P00A8

DTC P00A8, sometimes indicated as P00A800 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 2 circuit high bank 2.

The intake air temperature sensor 2 measures the temperature of the air entering the engine. When the sensor detects a high temperature, it sends a signal to the engine control unit (ECU) that causes the engine to run rich, or provide more fuel than necessary. This can result in poor fuel economy and increased emissions.
There are several possible causes of this DTC. One is a defective sensor. Another is a problem with the wiring or connectors. The most common cause, however, is a dirty or clogged air filter.

• P00A8: Intake Air Temperature Sensor 2 Circuit High Bank 2
• P00A8: Intake Air Temperature Sensor 2 Circuit High
• P00A8: Intake air temperature (IAT) sensor 2, bank 2 – circuit high
• P00A8 00: Intake air temperature (IAT) sensor 2, bank 2 - circuit high
