DTC codes / P22xx · Fuel and air metering (injector circuits) / P22EB
P22EB indicates that the powertrain control module (PCM) has detected an abnormally high voltage on the control circuit for the alternative fuel injector serving cylinder 5. This typically means the circuit is shorted to power, the injector coil is open, or the driver inside the PCM has failed, and the PCM may disable that injector to protect the circuit.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
