Procedure For Malfunction A

Procedure for malfunction A
1) Start engine and warm it up sufficiently.




2) Check the EGR valve lifting when revving engine from 2,000 rpm up to 4,000 rpm under no load.
EGR valve should lift up and down without sticking.
If EGR valve does not lift up and down, try again with either of the following methods:




With Consult
- Select "EGRC SOLENOID VALVE" in "ACTIVE TEST" mode with CONSULT and turn the solenoid valve "OFF".

Without Consult
- Disconnect EGR valve & EVAP canister purge control solenoid valve harness connector.
(The DTC for EGR valve & EVAP canister purge control solenoid valve will be displayed, however, ignore it.)




3) Check voltage between EGR temperature sensor harness connector terminal (1) and ground at idle speed. Less than 4.5V should exist.




4) Turn ignition switch "OFF".




Check harness continuity between EGR temperature sensor harness connector terminal (2) and ECM terminal (50).
Continuity should exist.
5) Perform "COMPONENTS INSPECTION", "EGR temperature sensor".
