General Description 

Courtesy of HONDA, U.S.A., INC.

The injector supplies fuel to the engine and is controlled by the powertrain control module (PCM) ON/OFF command. If the return signal according to the PCM drive command is abnormal for a specified number of times, a malfunction is detected and a DTC is stored.

Malfunction Threshold 

Any of the conditions occur at least 30 times (counts once per engine cycle):

• Symptom: Injector current not flowing

  The injector current is 0.2 A to 1 A or less*.

• Symptom: Injector over current

  The injector current is 12 A to 20 A or more*.

• Symptom: PCM terminal (to injector) short to ground

  The PCM terminal (to injector) voltage is 1 V to 1.3 V or less*.

• Symptom: PCM terminal (to injector) short to power

  The PCM terminal (to injector) voltage is 4.6 V to 5 V or more*.

• Symptom: Return signal abnormal

  The return signal does not change.

*: Varies with driving condition.

Diagnosis Details 

Conditions for setting the DTC 

When a malfunction is detected, the MIL comes on and a Pending DTC, a Confirmed DTC, the freeze data, and the on-board snapshot are stored in the PCM memory.

Conditions for clearing the DTC 

The MIL is cleared if the malfunction does not return in three consecutive trips in which the diagnostic runs. The MIL, the Pending DTC, the Confirmed DTC, the freeze data, and the on-board snapshot can be cleared with the scan tool clear command.
