Circuit Short to Ground
This fault gets logged if the boost
temperature sensor signal pin of EMS
ECU is short circuited to ground.
1.
EMS ECU disables SPC(Speed
Pilot Control) strategy, no more
sPC trim update
2.
EMS ECU disables the AMF
sensor learning
1.
Check for reference voltage supply 2 fault- P0651. Rectify this
fault by folowing its rectification procedure.
2.
Check electrical continuity between the EMS ECU pina
A34,A68 and the boost pressure and temperature sensor
connector pins 2,1. Rectify if any harness issues are found.
3.
Check whether the Boost temperature signal pin A34 is short
circuited to ground. If so then rectify the wiring harness
connections to make them inline with circuit schematics.
4.
Check for any physical damage of Boost pressure and
temperature sensor or its connector. Replace sensor/connector
if damages are found.
5.
Check for any rust/dirt on the sensor connector. If so then clean
the connector and refit it.
6.
If the problem still persdists then replace the boost pressure
and temperature sensor.
7.
IF the problem still persists then replace the EMS ECU.

Component Internal Failure 1. This fault gets logged due to VGT
actuator internal failures.
EMS ECU tyakes following
recovery actions:
1.
Apply reduce torque 3 mode:(70%
of torque cut off at 2700erpm).
2.
Disable SPC strategy, no more
sPC trim update.
3.
VGT position control disabled and
recovery position applied.
4.
Disable the AMF sensor learning.
5.
Disable the AMF plausibility test.
6.
Disable cruise control function.
7.
Disable EGR control and close
EGR valve.
1.
Check 30A fuse connected to EMS power relay and battery
(+ve) power supply is not blown off . Replace if required.
2.
Replace the VGT valve if this fault apears.
3.
Replace EMS ECU if problem still persists.
