P2A13Injection Pump Fuel Metering Control C Range/Performance (Cam/Rotor/Injector)
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- P2A13 flags metering element C of a diesel injection system as implausible: its circuit is electrically intact, yet the quantity or pressure it is supposed to produce does not follow the engine control module's command. The letter C stands for a third element – a further metering valve, a cam-driven pump plunger or a unit injector with its own solenoid. No manufacturer publishes P2A13. Volvo and Mack list this fault type for elements B, D and F on their 11 and 13 litre truck engines of the US17 emissions level, where it traced back to the rail pressure system or a slipping cam lobe. For C, the heavy-duty rule 13 CCR 1971.1 on injection quantity and pressure control is the basis. P2A14 and P2A15 cover low and high electrical readings. Output is usually derated.
- What you may notice
- Check engine light on
- Lack of power, especially under load
- Engine power derated by the control module
- Likely causes
- LikelyFault in the high-pressure system (leak, relief valve, low-pressure supply) that the element cannot compensate
- PossibleWorn or sticking metering element C (valve, plunger or cam lobe)
- RareOutdated engine control software or calibration
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
- Repair
- Hard · Usually a job for a workshop.Typical cost: €150 – €4,000
