P2A15Injection Pump Fuel Metering Control C 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
- With P2A15 the engine control module finds the circuit of metering element C reading too high: voltage where the driver expects a pulled-down line, or a current beyond the limit. Causes are a chafed wire touching battery voltage, a short between windings inside the actuator, or a failing output stage. Element C is the third metering element on engines that control several pump plungers, valves or unit injectors individually. P2A15 has no public manufacturer documentation. Saab's V6 diesel of 2002, whose pump carries two pressure valves, logs an internal valve short after 2.1 s and then caps pedal travel at 30 %, fuel at 20 mm³ per stroke and rail pressure at 60 MPa – an example of how strongly such a fault restricts the engine. P2A14 is the low-side fault.
- What you may notice
- Check engine light on
- Strongly limited power and accelerator response
- Engine may stall or refuse to start
- Likely causes
- LikelyShorted turns in the coil of metering element C drawing excess current
- PossibleControl wire of element C shorted to battery voltage
- RareOutput stage in the engine control module no longer switching correctly
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
