P2A02

DTC P2A02, sometimes indicated as P2A0200 is an OBD diagnostic trouble code indicating a manufacturer-specific fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the causing o2 sensor circuit range/performance bank 1 sensor 3.

The most common cause for this DTC is a bad oxygen sensor. The sensor may be damaged, or it may not be providing an accurate reading. If the sensor is damaged, it will need to be replaced. If the sensor is providing an accurate reading, the wiring or connectors may be damaged, or the computer may be incorrectly reading the sensor. In this case, the wiring or connectors may need to be repaired or the computer may need to be reset.
