What P2A15 means
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.
P2A15 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyMedium
- Typical labor0.5 to 5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2A15
- Check engine light on
- Strongly limited power and accelerator response
- Engine may stall or refuse to start
Common causes of P2A15
- Most likelyShorted turns in the coil of metering element C drawing excess current
- PossibleControl wire of element C shorted to battery voltage
- Less likelyOutput stage in the engine control module no longer switching correctly
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2A15 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. |
| 15 | The exact fault in that area. |
What to do next
- Note P2A15 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 P2A15
What does P2A15 mean?
P2A15 means "Injection Pump Fuel Metering Control C High (Cam/Rotor/Injector)". 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. It is a generic code, so it means the same on every make.
Is it safe to drive with P2A15?
Drive gently and only to a workshop. With P2A15 the car can go into limp mode (reduced power) to protect itself.
Will P2A15 fail an emissions test?
Yes, it can. P2A15 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 P2A15 to fix?
Difficulty: medium. A typical repair takes 0.5 to 5 hours of work. This is a job for a workshop.
Will P2A15 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
