P0265

Injector 2 Circuit Fault
DTC P0202
Fuel Injector fault - cylinder 2 Drive cycle A:Signal missing.

DTC P0264
Fuel Injector fault - cylinder 2 Drive cycle A:Signal out of range - below minimum.

DTC P0265
Fuel Injector fault - cylinder 2 Drive cycle A:Signal out of range - above maximum.

Possible causes by suggested order of priority:
^ Injector 2 open circuit.
^ Injector 2 short circuit.
^ Injector 2 driver (in ECM) stuck ON.
^ Injector 2 driver (in ECM) stuck OFF.
^ Fuse condition - F1 Engine Compartment Fusebox
^ Open circuit - C523/2 (NO) to C571/1 (NO).
^ Open circuit - C523/1 (YW) to C636/1 (YW).
^ Connector(s) C523,ECM C636 (B).

Injector 2 Open Circuit.
OPEN_CIRCUIT
^ Check resistance > 1M Ohm

Injector 2 Short Circuit.
SHORT_CIRCUIT
^ Check resistance < 5.0 ohms

Injector 2 driver (in ECM) stuck ON.
CHECK THE FOLLOWING:
^ Injector 2 driver (in ECM) stuck ON.
POSSIBLE FAULTS
^ Faulty ECM - Drive always energized (injecting) when ignition ON.
^ Harness cable connected to C523/1 (YW) shorted to ground - Valve always energized (injecting).

Note: Use multimeter to manually check components.

Injector 2 Driver (in ECM) Stuck OFF.
CHECK THE FOLLOWING:
^ Injector 2 driver (in ECM) stuck OFF.
POSSIBLE FAULTS
^ Faulty ECM - Injector never energized (no injection).
^ Harness cable connected to C523/1 (YW) shorted to battery positive - Injector never energized (no injection).

Note: Use multimeter to manually check components.

Fuse condition - F1 Engine Compartment Fusebox
POWER_DISTRIBUTION
^ Check for fuse not correctly inserted, fuse blown, fuse connections loose, damaged or corroded.
^ Certain diagnostics may also perform further checks to try and narrow down the fault, e.g. check if other circuits fed by the same fuse are also experiencing problems.

Open Circuit - C523/2 (NO) to C571/1 (NO).
OPEN_CIRCUIT
^ Check resistance > 1M Ohm

Open Circuit - C523/1 (YW) to C636/1 (YW).
OPEN_CIRCUIT
^ Check resistance > 1M Ohm

Connector(s) C523,ECM C636 (B).
CONNECTOR
^ Check for connector not correctly latched, backed out pins, damaged pins, corroded pins.
