199002669 - 1060GH DIESEL PRESSURE CHECK

CHECK TO BE PERFORMEDRESOLUTION IF THE CHECK IS NOT OK
1With the engine idling and warm, with all users off and the accelerator pedal not operated, the target Diesel Pressure and the measured Diesel Pressure must be in a range between 200 and 500 barsMove on to Step 3
2When the accelerator pedal is pumped several times, the measured Diesel Pressure must be in a range between 200 and 1500 bars.The test can be considered overMove on to Step 3
3Turn the ignition key to the OFF position.Disconnect the wiring harness connector from the fuel pressure sensor.Turn the ignition key ON. Measure the voltage between Pin 3 (wiring side) of the sensor and Earth, checking that it is within a range between 4.8 and 5.2 V.    See K083 FUEL PRESSURE SENSOR Move on to Step 5Move on to Step 4
4If faults are present, repair or if necessary replace the electrical wiring between the engine control unit and the fuel pressure sensor    See E5050 DIESEL ENGINES ELECTRONIC MANAGEMENT The test can be considered overReplace the engine management control unit    Op. 1060G80 DIESEL ELECTRONIC INJECTION CONTROL UNIT - R.R
5Measure the voltage between Pins 1 and 3 (wiring side) of the sensor. Check it is in a range between 4.8 and 5.2 V    See K083 FUEL PRESSURE SENSOR Move on to Step 4
6Measure the voltage between Pin 2 (wiring side) of the sensor and Earth, ensuring it is in a range between 4.8 and 5.2 V.    See K083 FUEL PRESSURE SENSOR Move on to Step 4
7Replace the pressure sensor and check the fault has disappeared    Op. 1060G28 FUEL PRESSURE SENSOR ON FUEL MANIFOLD TO INJECTORS - R.R Repair the original pressure sensor and replace the engine management control unit.    Op. 1060G80 DIESEL ELECTRONIC INJECTION CONTROL UNIT - R.R
