P0292 - Cylinder 11 Injector Control Circuit High

Technical Description
P0292 is set when the Engine Control Module (ECM) detects an abnormally high voltage within the fuel injector control circuit for cylinder 11. This typically signifies a short to voltage (B+) in the wiring harness or an internal short within the injector coil itself. The ECM monitors the injector circuit's duty cycle and peak/hold current; if the feedback signal remains high when the transistor should be pulling the circuit to ground, the fault is registered. On high-pressure systems like Common Rail Diesel or GDI, this can trigger a fail-safe mode, disabling the entire injector bank to prevent ECU damage.
Possible Causes
Short to voltage in the wiring harness for injector 11
Faulty fuel injector (internal short in solenoid coil)
Damaged pins or corrosion in the electrical connector
Faulty Engine Control Module (ECM) injector driver circuit

Mechanic's Tip
Before replacing expensive components, always double-check wiring and connections. 80% of all sensor faults are actually due to corroded contacts or broken wires.
