Component Testing: Notes

Static Test 

1. Ignition OFF, disconnect the harness connector at the high pressure fuel pump.
2. Test for 0.49 ohm plus/minus 0.023 ohm at 20°C (68°F) of resistance between FRP regulator low circuit terminal 1 and FRP regulator high circuit terminal 2.
   • If not within the specified range, 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.
