P2A19 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. 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.

Likely causes

Control line of element D shorted to battery voltage
Actuator coil of element D with shorted turns
Output stage in the control module stuck switched on

Symptoms

  • Warning lamp on immediately
  • Severe power reduction
  • Possible stalling or no start
