Sensor - AD
fault.
H
MIL is ON.
This DTC gets logged due
to fault registered in the AD
convertor in the ECU.
1. Check for Reference
voltage 1 fault is present.
2. Check sensor connections
for rust dirt etc.
3. Check Intermediate
connector.
4. Visually check sensor.
5. Check Electrical continuity.
6. Check ECU.
1. Check by erasing the fault once or twice.
2. If the problem keeps on repeating replace ECU.

Fuel Rail
Pressure
Sensor “A”
Circuit High.
H
1. MIL is ON.
2. Engine vibrations and noise.
3. Reduced torque mode activated/ vehicle
lacks performance.
4. Stops the Engine after few seconds;
5. Disables the Pilot Injection; RVD; EGR;
6. Allows the IMV to operate without trim
values.
7. Deactivates the Leak Detection test;
8. Forces the IMV to open fully.
9. Limits the System Pressure demand to
800bar.
10. Deactivates the Rail pressure
sensing/Measurement.
11. Rail Pressure Build measurement is
deactivated.
12. Disables the Rail pressure control fault
detection.
13. Limp Home Mode activated.
This DTC gets logged if the
Rail pressure measured is
more than upper threshold;
once the engine is started
and running.
1. Check for Reference
voltage 1 fault or If P1190 is
present.
2. Check High pressure
circuit for fuel leakages.
3. Check sensor connections
for rust dirt etc.
4. Visually check sensor for
damages.
5. Check Electrical continuity.
6. Check ECU.
1. Check fuel level in the tank is above minimum
level (fuel level gauge).
2. Check for Reference voltage 1 fault or If P1190 is
present; if noticed follow Reference voltage1 check
and rectification Procedure.
3. Check High pressure circuit for fuel leakages;
Rectify leakages by proper fitment/replacement of
component.
4. Check sensor connections for rust dirt etc.; clean
the sensor connections and ensure proper fitment.
5. Visually check sensor for damages; Follow
Electrical continuity check procedure; Replace/
Rectify Harness if required.
6. Check Electrical continuity between ECU pins 77,
40, 58 and rail pressure sensor connector as per
circuit schematic; establish the continuity if problem
exists. Check whether the EMS ecu pin 40 is short
circuited to battery. If so, rectify the wiring harness
connections.
7. Check for damages of the sensor; replace
sensor-rail assembly if damaged or problem
persists.
8. Check ECU; if problem still persists replace the
ECU.
9. 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 rail pressure value of 800 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.
