Short To Ground Check
- Ignition switch is turned "OFF". Disconnect FPCM, fuel pressure sensor connector.
- Measure the resistance between power terminal of fuel pressure sensor harness connector and chassis ground.
Specification: Infinite ∞Ω
- Is the measured resistance within specification?
YES
- Substitute with a known-good FPCM and check for proper operation. If the problem is corrected, replace FPCM and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
NO
- Repair short in harness. Go to "VERIFICATION OF VEHICLE REPAIR " procedure.
