Code P020A Dodge Description

The Powertrain Control Module (PCM) can detect when unintended fuel injection occurs by monitoring fuel rail pressure and engine speed. If this condition occurs, the engine will typically die and not start. There will be exhaust smoke during cranking and no fuel rail pressure will be developed during cranking. This Detected Trouble Code (DTC) will be active during cranking if this condition exists. Progressive cylinder damage may occur if the engine is operated for an extended period of time with this condition. This fault code is logged when the PCM determines that unintended fuel injection has occurred. The PCM sets the OBDII code when determines that unintended fuel injection has occurred.
