Circuit Description
Fuel injector is a solenoid operated driver. Fuel injectors receive 12 volts from ignition switch through a fuse. PCM provides ground path for each injector through individual driver circuits. PCM monitors the circuits for proper voltage levels. When an improper voltage level occurs, driver signals PCM. DTC will set when PCM detects an improper voltage level in fuel injector circuit.
For duplication of DTC, ensure no system voltage DTCs are set and system voltage should be 11-16 volts.
