Component Testing: Notes

Static Test 

1. Ignition OFF, disconnect the harness connector at the high pressure fuel pump.
NOTE: The DMM and test leads must be calibrated to 0 Ω in order to prevent misdiagnosis.
2. Test for 0.35-0.6 Ω at 20°C (68°F) between low control circuit terminal 1 and high control circuit terminal 2.
   • If the resistance is less than 0.3 Ω or greater than 0.6 Ω, replace the high pressure fuel pump.
3. Test for infinite resistance between each terminal and the high pressure fuel pump housing/case.
   • If not the specified value, replace the high pressure fuel pump.
