What P2A19 means
P2A19 is stored when the circuit of metering element D reads high – for instance a control line shorted to battery voltage, an actuator coil with shorted turns pulling excessive current, or a driver that no longer switches off. The fault is electrical; whether the element would still meter correctly cannot be judged until the circuit is repaired. Element D exists only on systems with four or more separately controlled metering elements. No manufacturer documents P2A19 publicly. Saab's 2011 9-5 diesel illustrates the pattern on its single regulator: a short to voltage lasting more than one second sets P0254 as a Type A fault, lighting the warning lamp at once. P2A18 covers the opposite direction, P2A17 the functional fault of the same element.
P2A19 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 P2A19
- Warning lamp on immediately
- Severe power reduction
- Possible stalling or no start
Common causes of P2A19
- Most likelyControl line of element D shorted to battery voltage
- PossibleActuator coil of element D with shorted turns
- Less likelyOutput stage in the control module stuck switched on
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2A19 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. |
| 19 | The exact fault in that area. |
What to do next
- Note P2A19 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 P2A19
What does P2A19 mean?
P2A19 means "Injection Pump Fuel Metering Control D High (Cam/Rotor/Injector)". P2A19 is stored when the circuit of metering element D reads high – for instance a control line shorted to battery voltage, an actuator coil with shorted turns pulling excessive current, or a driver that no longer switches off. It is a generic code, so it means the same on every make.
Is it safe to drive with P2A19?
Drive gently and only to a workshop. With P2A19 the car can go into limp mode (reduced power) to protect itself.
Will P2A19 fail an emissions test?
Yes, it can. P2A19 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 P2A19 to fix?
Difficulty: medium. A typical repair takes 0.5 to 5 hours of work. This is a job for a workshop.
Will P2A19 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
