Component Inspection

Check fuel pressure sensor performance
1. IG "OFF".
2. Engine start.
3. Measure the voltage between signal terminal of fuel pressure sensor harness connector and ground.
  Specification: approx. 1.9 ~ 3.2V (in idle)
4. Is the measured voltage within specification?
  YES
  - Visually check contamination by foreign material at fuel pressure sensor and Clear DTC and Test-drive under the enable conditions. After the road test, go to "VERIFICATION OF VEHICLE REPAIR ".
  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.
