DIAGNOSTICS - ENGINE CONTROL SYSTEM 04-263

(e) Use a multimeter to measure the resistance
between the pin 3, 4 of EGR valve connector
E18 and the pin 96, 66 of ECM connector E01
respectively.

Is the inspection result normal?
YES>To step 4.

No > Maintain or replace the harness.

4 . Replace EGR valve
(a) Replace DPF pressure 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.
