EGR TEST

Is the result OK?

YES

Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the EGR valve and the PCM. If the on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the on-board snapshot .

NO

The failure is duplicated. Go to step 2.

Determine possible failure area (EGR valve position sensor, others)

-1. Turn the vehicle to the OFF (LOCK) mode.

-2. Turn the vehicle to the ON mode.

-3. Check the parameter(s) below with the HDS.
