194003935 - 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 | Turn the ignition key OFF.Disconnect the cable loom connector from the particle filter temperature sensor downstream of the catalytic converterTurn the ignition key ON.Check that the voltage across pin 1 and 2 of the sensor See K190 DOWNSTREAM PARTICULATE FILTER TEMPERATURE SENSOR (DPF)is 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 SYSTEMReplace the wiring if necessary.The test can be considered over | Replace the engine management control unit Op. 1060G80 DIESEL ELECTRONIC INJECTION CONTROL UNIT - .R |
| 4 | Turn the ignition key OFF.Check that the resistance across pin 1 and 2 of the sensor See K190 DOWNSTREAM PARTICULATE FILTER TEMPERATURE SENSOR (DPF)is between 200 and 600 Ohm | 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 |
