Step
Check the common rail pressure sensor
circuit harness for open wiring or short.
1.
Starter switch "OFF".
2.
Disconnect the ECM.

Disconnect the common rail pressure
sensor connector.
4.
Jumper the common rail pressure sensor
connector
resistance at the ECM connector.
Was the resistance within range?
13
Repair or replace the faulty harness.
14
Is the action complete?
Check the common rail pressure.
1.
Install Tech 2.
2.
Starter switch "ON".
3.
Observe "Desired Rail Pressure" and
"Actual Rail Pressure" displays.
4.
Start the engine. Run the engine at idle
for warm-up.
15
5.
Observe "Desired Rail Pressure" and
"Actual Rail Pressure" displays again.
Does the actual common rail pressure
increase following the desired pressure?
Replace the common rail (common rail
pressure sensor).
16
Is the action complete?
Check DTC245 will not be set again.
1.
Restore the vehicle.
