Signal Circuit Inspection of fuel pressure sensor
WARNING: This page is about a different variant/trim than selected.
■ Short to ground check
- IG "OFF". Disconnect fuel control module, fuel pressure sensor connector.
- Measure the resistance between power terminal of fuel pressure sensor harness connector and ground.
Specification: infinite
- Is the measured resistance within specification?
YES
- Go to next procedure.
NO
- Repair contact resistance or open in harness. Go to "VERIFICATION OF VEHICLE REPAIR " procedure.
■ Open check
- IG "OFF". Disconnect fuel control module, fuel pressure sensor connector.
- Measure the resistance between signal terminal of fuel pressure sensor and fuel control module harness connector.
Specification: below 1 Ω
- Is the measured resistance within specification?
YES
- Go to "COMPONENT INSPECTION " as follows.
NO
- Repair contact resistance or open in harness. Go to "VERIFICATION OF VEHICLE REPAIR " procedure.
