What P2A14 means
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.

Symptoms of P2A14
- Check engine light on
- Reduced power or limp mode
- Rough running or misfire-like shaking
Common causes of P2A14
- Most 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
- Less likelyFaulty output stage in the engine control module
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2A14 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| A | Area: hybrid propulsion. |
| 14 | The exact fault in that area. |
What to do next
- Note P2A14 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2A14
What does P2A14 mean?
P2A14 means "Injection Pump Fuel Metering Control C Low (Cam/Rotor/Injector)". P2A14 reports that the signal in the drive circuit of fuel metering element C has fallen below its expected window. It is a generic code, so it means the same on every make.
Is it safe to drive with P2A14?
Drive gently and only to a workshop. With P2A14 the car can go into limp mode (reduced power) to protect itself.
Will P2A14 fail an emissions test?
Yes, it can. P2A14 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P2A14 to fix?
Difficulty: medium. A typical repair takes 0.5 to 4 hours of work. This is a job for a workshop.
Will P2A14 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
