- The rail pressure sensor initial values
are lower than specified values with
the ignition "ON".
• Minimum sensing values: - 90 bar
(Open)
- Check the supply voltage to sensor.
• Output voltage at 1600 bar: 4.055 ±
0.125 V
• Output voltage at atmospheric
pressure: 0.5 ± 0.04 V
- Check the sensor and ECU wiring
harness.
• Check the ECU pin #25, #26 for open
and poor contact.
• Check the fuel rails and high pres-
sure pipes for leaks.
- Check the fuel rail pressure sensor.
- Replace the ECU if required.
- The rail pressure sensor initial values
are higher than specified values with
the ignition "ON".
• Maximum sensing values: 90 bar
