P2A2EAlternative Fuel Tank Shutoff Valve E Control Circuit/Open
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- How the car detects it
- P2A2E is the open-circuit fault for shutoff valve E, the last letter of this series, so it only applies to systems with at least five gas cylinders, such as transit buses or heavy trucks. The module notices that the coil draws no current when commanded. No manufacturer documents P2A2E publicly, and TransEco's AFCM table lists valve E only with its Low and High codes. New Flyer offers a practical check: if the engine fails to start, confirm that the door of the fill box is shut and the solenoid wires are plugged in, because an open door also keeps all tank valves shut. Swapping the coil with a neighbour tells a coil fault from a wiring fault. CARB's monitoring rules for output components apply.
