No >Maintenance related faults.
5 . Check EGR system
(a) Check whether EGR system has air leakage.
Is the inspection result normal?
04 YES>To step 6.
No >Maintenance related faults.
6 . Check the intake manifold pressure temperature sensor
(a) Check whether the intake manifold pressure temperature sensor is installed correctly.
(b) Remove the intake manifold pressure temperature sensor
(c) Check whether the sensing hole is blocked or not, and whether the resistance between
the terminals is in line with the standard or not.
(d) Check whether the intake manifold pressure temperature sensor is dirty.
(e) Ignition switch: ON, and read the data flow of the intake manifold pressure temperature
sensor shown on the diagnostic tool.
Is the inspection result normal?
YES>To step 7.
No >Clean and change the default parts.
7 . Replace ECM
(a) Replace ECM. (Refer to "Chapter 11 Engine control system, Engine control module")
(b) Check the data flow of the engine, and make sure the engine phenomenon does not
