Check rail pressure performance
WARNING: This page is about a different variant/trim than selected.
- IG "OFF".
- Engine start.
- Monitor signal waveform of rail pressure sensor with accelerating and decelerating.
Specification: The rail pressure will be increased while accelerating the vehicle.
- Is the measured signal waveform normal?
YES
- go to "VERIFICATION OF VEHICLE REPAIR " procedure.
NO
- Substitute with a known - good rail pressure sensor and check for proper operation. If the problem is corrected, replace rail pressure sensor and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
