DIAGNOSTICS - ENGINE CONTROL SYSTEM 04-317
(g) Use a multimeter to measure the resistance
between the pin 2, 3 of DPF temperature
sensor connector Q01 and the ground.
Standard resistance
Multimeter connection
Standard value
pin 04
Q01(2)- ground >10 MΩ
Q01(3)- ground >10 MΩ
Is the inspection result normal?
YES>To step 4.
No > Maintain or replace the harness.
4 . Replace DPF temperature sensor
(a) Replace DPF temperature sensor.
(b) Use a diagnostic apparatus to perform DTC verification procedures.
(c) Implement the steps to read sensor data stream.
(d) Check whether DTC exists.
Is the inspection result normal?
YES>Replace DPF temperature sensor
NO >To step 5.
5 . Replace ECM
(a) Replace ECM.
(b) Use a diagnostic apparatus to perform DTC verification procedures.
(c) Implement the steps to read sensor data stream.
(d) Verify that no DTC exists and the data are normal.
