Malfunction Threshold

Any of the conditions occurs at least 60 times (counts 4 times per engine cycle).

• Symptom: High pressure fuel pump current not flowing

  The pump solenoid current is 0.4 A to 1.5 A or less*.

• Symptom: High pressure fuel pump overcurrent

  The pump solenoid current is 19.7 A to 30.5 A or more*.

• Symptom: PCM terminal (to high pressure fuel pump) short to ground

  The PCM terminal (to high pressure fuel pump) voltage is 1.8 V to 2.2 V or less*.

• Symptom: PCM terminal (to high pressure fuel pump) short to power

  The PCM terminal (to high pressure fuel pump) voltage is (12 volt battery voltage - 3.2) V to (12 volt battery voltage - 2.2) V or more*.

*: Varies with driving condition
