939010228 - 1080BH DPF INPUT TEMPERATURE SENSOR OPERATION CHECK
| STEP | CHECK TO BE PERFORMED | RESOLUTION IF THE CHECK IS NOT OK |
|---|---|---|
| 1 | Check whether error P2084 - Temperature sensor on particulate filter input - is present using the diagnostic equipment | Replace the temperature sensor Op. 1080B83 EXHAUST GAS TEMPERATURE SENSOR ON PARTICULATE FILTER (D.P.F.) - R R |
| 2 | Press the START/STOP button and turn off the engine.Disconnect the wiring harness connector from the temperature sensor downstream of the catalytic converterPress the START/STOP button.Check that the voltage across pin 1 and 2 of the sensor See K188 CAT. DOWNSTREAM TEMPERATURE SENSORis greater than 4.8 V.Move on to Step 4 | Move on to Step 3 |
| 3 | If faults are found, restore the wiring between the engine control unit and the downstream temperature sensor See E5070 PARTICLE FILTER SYSTEM Replace the wiring if necessaryThe test can be considered over | Replace the engine management control unit Op. 1060G80 DIESEL ELECTRONIC INJECTION CONTROL UNIT - .R |
| 4 | Press the START/STOP button.Check that the resistance across pin 1 and 2 of the sensor See K188 CAT. DOWNSTREAM TEMPERATURE SENSORis between 200 and 600 Ohms | Replace the temperature sensor Op. 1080B83 EXHAUST GAS TEMPERATURE SENSOR ON PARTICULATE FILTER (D.P.F.) - R R |
| 5 | Replace the engine management control unit Op. 1060G80 DIESEL ELECTRONIC INJECTION CONTROL UNIT - .R |
