Maximum Rail Pressure
Control Malfunction (IMV
Fault)

Minimum Rail Pressure
Control Malfunction (IMV
Fault)

- Rail pressure faults: Too high

- Check the IMV wiring harness.

- Check the ECU wiring harness.

• Check the ECU pin #87 for open and

short.

- Check the high pressure fuel lines, fuel

rails and high pressure pipes for leaks.

- Check the rail pressure sensor.

• Supply voltage: 5 ± 0.1 V

• Output voltage at 1600 bar: 4.055 ±

0.125 V

• Output voltage at atmospheric

pressure: 0.5 ± 0.04 V

- Check the transfer pressure fuel pres-

sure lines.

• Check the fuel level in fuel tank.

Check the fuel system for air influx.

• Check the fuel filter specification.
