P0264

DTC P0264 Cylinder 2 - Injector Circuit Low Input

Component Location:

DESCRIPTION

Based on information from various sensors, the ECM measures the fuel injection amount. The fuel injector is a solenoid-operated valve and the fuel injection amount is controlled by length of time the fuel injector is held open. The ECM controls each injector by grounding the control circuit. When the ECM energizes the injector by grounding the control circuit, the circuit voltage should be low (theoretically 0V) and the fuel is injected. When the ECM de-energizes the injector by opening control circuit, the fuel injector is closed and circuit voltage should be peak for a moment.

DTC DETECTING CONDITION

1. DTC Description
ECM sets DTC P0261, P0264, P0267 or P027O respectively if the ECM detects that injector (Cylinder #1, 2, 3 or 4) control line is short to ground.
