DTC codes / P2Exx · Hybrid propulsion / P2E67
P2E67 indicates that the powertrain control module has detected a fault in the engine coolant bypass valve circuit, specifically that valve E is stuck in the closed position. The computer commands the valve to change position and monitors the circuit or feedback signal, but the valve does not respond as expected, remaining closed when it should open.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
