P2A1DInjection Pump Fuel Metering Control E High (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
- P2A1D tells that metering element E's circuit sits above its plausible range. Faults that cause it include a lead rubbing through onto a powered wire, moisture bridging pins, an actuator winding shorted internally so that current climbs, or a defective output stage in the control unit. Element E only exists where five or more metering elements are driven individually. No manufacturer publishes P2A1D. Saab's 2002 V6 diesel offers a comparison: an internal short in one of its pump's two pressure valves persisting for more than 2.1 s sets P0259, and the workshop guidance recommends moving the harness while watching the meter to find intermittent shorts. The low reading of the same element is P2A1C.
