STATUS

P0194

Fuel Rail

Pressure

Sensor “A”

Circuit

Intermittent /

Erratic.

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.

1. This DTC gets logged

due to drop in rail pressure.

2. Leak in high pressure

fuel line.

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 adequate fuel is available in the tank.

2. Check there is no air entry in to the low pressure

fuel line.

3. Ensure fuel filter is not clogged.

4. Ensure there is no leakage in the high pressure

fuel line.

5. Check & ensure connector for proper fitment

6. Check for Reference voltage 1 fault or If P1190 is

present; if noticed follow Reference voltage1 check

and rectification Procedure.

7. Check High pressure circuit for fuel leakages; if

noticed rectify leakages by proper

fitment/replacement of component.

8. Check sensor connections for rust; dirt and loose

connection; etc.; if found clean the sensor

connections and ensure proper fitment.

9. Visually check sensor for damages; Follow

Electrical continuity check procedure. Replace/

Rectify Harness if required.

10. Check Electrical continuity between ECU and

rail pressure sensor connector as per circuit

schematic.

11. Replace sensor-rail assembly if damaged or if

problem persists.

12. Check ECU; if problem still persists replace

ECU.

13. 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.

P0216

Injector/Injection

Timing Control

Circuit.

Engine vibration / restricted Fly-up.

Current too high on Bank 1.

1. Check Injectors for OC.

2. Check Injectors for

electrical Fault.

3. Check Electrical Isolation.

4. Check ECU.

1. Correct OC and ensure proper connector fitment.

2. Disconnect all injectors and key on. If problem

persists rectify harness.

3. Else locate faulty injector by connecting one at a

time and checking for fault. Replace faulty injector.

4. Follow Electrical continuity check procedure.

Replace/ Rectify Harness if required.

5. Replace ECU; if problem still persists.
