<<See All OBD Codes

The trouble code P0A29 can be elucidated as Hybrid Battery Power Off Circuit High. If the engine control module would detect a variation in the voltage coming from the hybrid battery that is outside the parameters set by the automobile manufacturer, then it would store the P0A29 fault code. This would give rise to the flashing up of the check engine light.
