Monitored & Set Conditions

Fuel injector operation is monitored when battery voltage is more than 12 volts, Auto Shutdown (ASD) relay is energized, fuel injector pulse width is less than 10 milliseconds and engine speed is less than 3000 RPM. DTC will be stored in Powertrain Control Module (PCM) memory when no inductive impulse is sensed after fuel injector turns off with no other fuel injectors turned on. Possible causes for DTC to set are: intermittent condition, defective fuel injector, defective ASD relay circuit, defective PCM, or defective connectors or wiring.
