P2A14Injection Pump Fuel Metering Control C Low (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
- P2A14 reports that the signal in the drive circuit of fuel metering element C has fallen below its expected window. In practice the control module sees too little voltage or current on that output, as happens when the line touches ground or, depending on the driver design, an open wire. C denotes a third metering element besides A and B, found only on pumps or engines with several separately driven elements. No maker documents P2A14 publicly. Saab's 2011 9-5 diesel shows how such a check works for its single regulator: a control line shorted to ground for longer than one second sets P0253 as an immediate Type A fault. California's comprehensive component rules require this circuit check for every such actuator. Limited power and rough running are typical; P2A15 is the high-side counterpart.
- What you may notice
- Check engine light on
- Reduced power or limp mode
- Rough running or misfire-like shaking
- Likely causes
- LikelyControl wire of element C chafed through and shorted to ground
- PossibleBroken wire or corroded, loose connector pin in the element C circuit
- PossibleCoil of metering element C open or shorted to its housing
- RareFaulty output stage in the engine control module
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
