18.
Check whether High pressure pump is functioning properly/able
to build pressure else replace high pressure pump.
19.
Check whether IMV is Stuck closed, if so replace the IMV.
20.
After rectification ensure the following before handing over to
customer.
a) Rail pressure at ignition key on is < 10 bar.
b) By removing the rail pressure sensor connector shows a
very rail pressure value in bar,
c) High pressure leak detection test can be carried out.
d) Please drive the vehicle on road,check and ensure rail
pressure feed-back follows the demand continuously.(feedback
and demand parameters can be monitored by using diagnostic
tool).

P0093
7A
Fluid Leak or Seal Failure
This fault gets logged if the Interpolated
value used to calculate the torque
limitation by the VLC strategy is over a
threshold or clamped or if EMS ECU
detects a heavy drop in rail pressure
due to large leaks
1.
EMS ECU Activates delayed
engine stop request.
1.
Check 30A fuse connected to EMS power relay and battery
(+ve) power supply is not blown off . Replace if required.
2.
Check electrical continuity between ECU pin no A38, A35 &
A19 to Rail pressure sensor connector no 3 ,1, 2.
3.
Check electrical continuity of wiring harness between ECU pin
A77 and IMV connector pin 2 & EMS main relay supply and
IMV connector pin 1. rectify wiring harness connections in case
of any issue.
4.
check whether the IMV control pin of EMS A77 is short circuited
to ground because of wrong wiring harness connections. If so
rectify the wrong connections to make the connections inline
with circuit schematics.
5.
Check adequate fuel level is available in the tank.
6.
Check high pressure fuel lines for leakage.
7.
Check fuel filter is not clogged.
8.
Check low pressure fuel lines for air entry.
9.
Check & ensure connector for proper fitment.
10.
Check rail pressure sensor for oxidation, rust etc, if observed
clean deposit.
11.
Check harness for damages; Replace / Repair if harness is
damaged.
12.
Check ECU pins and connector for damage, Replace if found
defective.
13.
Please check if any injector back leak is abnormaly high
compared to other injectors.
14.
Check whether High pressure pump is functioning properly else
replace high pressure pump.
15.
Check whether IMV is Stuck closed, if so replace the IMV.
16.
After rectification ensure the following before handing over to
customer. ~ a) Rail pressure at ignition key on is < 10 bar,~ b)
By removing the rail pressure sensor connector shows a very
rail pressure value in bar, ~ c) High pressure leak detection
test can be carried out. ~ d) Please drive the vehicle on
road,check and ensure rail pressure feed-back follows the
demand continuously.(feedback and demand parameters can
