P2A1EInjection Pump Fuel Metering Control F (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
- P2A1E is the general fault of the sixth fuel metering element, F – the last letter of this code family. The control module stores it for a failure of that element that it cannot pin down as a plausibility (P2A1F), low (P2A20) or high (P2A21) fault. Six individually metered elements would fit, for example, a six-cylinder engine with one pumping unit or unit injector per cylinder. Volvo and Mack, whose 13 litre truck engines use three cam-driven pumping injectors on a common rail, name element F in service bulletins, but only with the range/performance code P2A1F. No source describes P2A1E itself; the CARB rules for fuel system and electrical components set the frame. Typical consequences are a warning lamp and derated power.
- What you may notice
- Check engine light on

- RareEngine control module fault
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
