■ Visual inspection of fuel line
- Check the fuel line for following conditions:
- Damage or leaking fittings and seals
- Bent or restricted fuel line.
- Has a problem found in this procedure?
YES
- Repair as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
NO
- Go to "Check blockage and leakage of fuel line" as follows
■ Check blockage and leakage of fuel line
- Disconnect hose between high pressure fuel pump and fuel pump.
- Remove fuel remained in the hose.
- Check that air can pass through the hose by blowing air into the hose by air gun.
- Has a problem found in this procedure?
YES
- Repair as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
NO
- Go to "COMPONENT INSPECTION " as follows
■ Check fuel pressure sensor performance
- IG "OFF".
- Engine start.
- Measure the voltage between signal terminal of fuel pressure sensor harness connector and ground.
Specification: approx. 1.9 ~ 3.2V (in idle)
- Is the measured voltage normal?
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
- Substitute with a known - good fuel pressure sensor and check for proper operation. If the problem is corrected, replace fuel pressure sensor and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
