EGR SOLENOID OPERATION CHECK

Check 1080CB

1.9 JTD 8v, 1.9 JTD 16v, 2.4 JTD 20v

CHECK TO BE PERFORMEDRESOLUTION IF THE CHECK IS NOT OK
1

Press the START/STOP button and turn off the engine.

Disconnect the cable loom connector from the EGR solenoid

See L030 EGR SOLENOID VALVE

Press the START/STOP button.

Measure the voltage between Pin 1 of the wiring side connector and Earth. Ensure it is greater than 11V.

Press the START/STOP button.

Move on to Step 4

Move on to Step 2
2

In the engine compartment junction unit, remove fuse F11 (third in the lower row)

See B001 ENGINE COMPARTMENT JUNCTION UNIT

Press the START/STOP button.

Check the voltage between the fuse inlet contact and earth. Ensure it is greater than 11 V.

Replace the junction unit

Op. 5505A13 ADDITIONAL JUNCTION UNIT IN ENGINE COMPARTMENT - R.R.

3

If fualts are present, repair or if necessary replace the electrical wiring between the engine compartment junction unit and the solenoid.

See E5050 DIESEL ENGINES ELECTRONIC MANAGEMENT

The test can be considered over

Repair or if necessary replace the electrical wiring between the engine control unit and the solenoid

See E5050 DIESEL ENGINES ELECTRONIC MANAGEMENT

5

Press the START/STOP button. Measure the resistance between Pin 2 of the EGR solenoid wiring side connector and Earth. Ensure it is greater than 500 kOhm.

See L030 EGR SOLENOID VALVE

Repair or if necessary replace the electrical wiring between the engine control unit and the solenoid

See E5050 DIESEL ENGINES ELECTRONIC MANAGEMENT

6

Measure the resistance between Pin 2 of the EGR solenoid wiring side connector and Pin 60 of engine control unit wiring side connector B. Ensure it is less than 5 Ohms.

See L030 EGR SOLENOID VALVE

See M010 ENGINE MANAGEMENT CONTROL UNIT

Reconnect the cable loom connectors to the EGR solenoid and the engine management control unit

See L030 EGR SOLENOID VALVE

See M010 ENGINE MANAGEMENT CONTROL UNIT

Repair or if necessary replace the electrical wiring between the engine control unit and the solenoid

See E5050 DIESEL ENGINES ELECTRONIC MANAGEMENT

7

Replace the solenoid and check that the fault has disappeared

Op. 1080C24 E.G.R. SYSTEM SOLENOID - R + R

Repair the original EGR solenoid and replace the engine management control unit
