DTC codes / P2Exx · Hybrid propulsion / P2E6A
P2E6A indicates that the engine computer has detected a lean fuel mixture condition specifically while cylinder deactivation is active on Bank 2 of the engine. The powertrain control module monitors oxygen sensor feedback and fuel trim during the deactivation event, and it sets this code when the exhaust oxygen content indicates too much unburned oxygen, meaning the active cylinders on that bank are receiving insufficient fuel relative to air.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
