Symptom:
P-0204 INJECTOR #4 CONTROL CIRCUIT
When Monitored and Set Condition:
P-0204 INJECTOR #4 CONTROL CIRCUIT
When Monitored: With battery voltage greater than 12 volts, the auto shutdown relay
energized, injector pulse width less than 10ms, and engine speed less than 3000 rpm.
Set Condition: This trouble code takes .64 to 10.0 seconds to set when no inductive kick
is sensed .18ms after injector turn off, and with no other injectors on.
POSSIBLE CAUSES
ASD RELAY OUTPUT CIRCUIT OPEN
INJECTOR #4 DEFECTIVE
INJECTOR #4 DRIVER CIRCUIT OPEN
INJECTOR #4 DRIVER CIRCUIT SHORTED TO GROUND
