Performance or Incorrect
Operation
This fault gets logged if difference
between 'Corrected EGR valve position
demand' and 'EGR valve position
corrected with the "zero position" offset'
is over a threshold during a calibratable
time.
EMS ECU takes following recovery
actions:~
1.
Disables the AMF sensor learning.
2.
Disables the AMF plausibility test.
3.
Disables cruise control function.
4.
Disables EGR control and close
EGR valve.
5.
Applies reduce torque mode:(80%
of torque).
6.
Disable SPC(Speed Pilot Control)
strategy, no more SPC trim
update.
1.
Check the electrical continuity between the EMS ECU pins A83
and A84 to the EGR valve DC motor connector pins 2 & 1.
Rectify if any wiring harness connectivity issues are found.
2.
Check for rust/dirt on the connector and clean it if any rust/dirt
found.
3.
Check whether EMS ECU pins A83 & A84 are either short
circuited to vbatt/ground/short circuited across. If so, then
rectify the wiring harness connections.
4.
Check the continuity between the EMS ECU pins A65, A16,A20
and the motorized EGR actuator connector pins 3,5 & 4.
Rectify if any issues found.Check for any reference voltage
supply 3 faults (P0697), if so then follow the rectification
procedure of those faults.
5.
Check whehther the EMS ECU feedback sensor signal pin is
short circuited to battery supply/Ground due to wrong wiring
harness connections, if so then rectify the wiring harness
connections to make them inline with circuit schematics.
6.
Check sensor for oxidation, rust etc, if observed clean deposit
7.
Check for rust/dirt accumulated on the sensor connector, if
found clean the connector and refit it.
8.
If still problem persists then replace the motorized EGR
actuator.
9.
If still problem persists then replace the EMS ECU.
10.
Ensure whether the EGR demand and feedback parameters
are matching before handing the vehicle to customer.
