Short To Ground Check

1. IG "OFF". Disconnect FPCM, fuel pressure sensor connector.
2. Measure the resistance between power terminal of fuel pressure sensor harness connector and chassis ground.

   Specification  : Infinite

   • Fault is intermittent. Go to "VERIFICATION OF VEHICLE REPAIR " procedure.
3. 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.
