- IG "OFF" & Disconnect fuel rail pressure sensor and PCM connector.
- Measure resistance between ground terminal of fuel rail pressure sensor harness connector and chassis ground.
Specification: below 1Ω
- Is the measured resistance within specification?
YES
- Go to "COMPONENT INSPECTION " procedure.
NO
- Repair open or contact resistance in ground circuit of the fuel rail pressure sensor and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
