P2A1AInjection Pump Fuel Metering Control E (Cam/Rotor/Injector)
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P2A1A covers fuel metering element E in general: the engine control module has seen a malfunction of that element but files it under none of the more specific codes for plausibility (P2A1B) or low and high signal (P2A1C, P2A1D). A fifth separately driven element is rare; it presupposes engines that meter fuel per cylinder or per pumping unit. Delphi's F2E heavy-duty system, used by Volvo, Renault Trucks and Hyundai on six-cylinder engines, pairs a common rail with six injectors, half of them pumping and half plain, and the 16 litre version uses six pumping injectors – a layout where letters up to F could be assigned. Whether any maker actually reports P2A1A is not published; the CARB monitoring rules remain the basis. Reduced power is the likely reaction.
