nce.

1. Engine does not start.

2. Engine vibrates at certain speeds.

This DTC gets logged if the

ECU does not receive the

cam sensor signal within

the defined window w.r.t

crank signal (instead

receives it outside the

window.)

If the cam movement is

detected but the cam

events are not in the

expected window position;

if the rising and falling edge

of the cam flank is detected

wrongly.

1. Visually check sensor.

Check for metallic

particles/burr in sensor tip

and flywheel teeth.

2. Check sensor connections

for rust dirt etc.

3. Check Electrical continuity.

4. Check cam shaft flag.

5. Check the TDC setting /

timing setting of crankshaft;

cam shaft and HP pump.

6. Check ECU.

1. Check for sensor reference voltage supply 2

faults and rectify these faults if any by following

their rectification procedure. Check sensor

connections for rust dirt etc. Ensure clean

connector pins and proper fitment.

2. Check Electrical continuity between ECU pins 15,

14 and crank sensor connector as per circuit

schematic; follow Electrical continuity check

procedure. Check Electrical continuity between

ECU pins 78, 34, 16 and Cam sensor connector as

per circuit schematics; if necessary replace/ rectify

the harness. Replace/ Rectify Harness if required.

Check whether the EMS ecu pins 14/34 are short

circuited to battery/ground. If so then rectify the

wiring harness connections.

3. Check cam shaft; Replace cam shaft if found

faulty.

4. Check for timing gear is o.k. if found faulty

replace it.

5. Visually check sensor. Check for metallic

particles/burr in sensor tip; Clean the sensor tip and

cam to remove any foreign particle.

6. Check for crank signal also.

P0371

Timing

Reference High

Resolution

Signal “A” Too

Many Pulses.

1. Engine does not start.

2. Engine vibrates at certain speeds.

This DTC gets logged due

to too many pulses from the

crank sensor. In other

words if two consecutive

crankshaft events ( i.e. 2

missing teeth) are too close

to the previous one

detected;

1)Noise signal in the crank

sensor signal path

2). Excessive engine

acceleration.

Normal engine acceleration

is taken in to account

before raising this fault.

Numbers of early events (3)

are monitored per gap

cycle before raising the

fault.

1. Check crank sensor to

flywheel air gap to be

between 0.7 to 1.3 mm.

2. Check sensor connections

for rust dirt etc.

3. Check Electrical continuity.

4. Check crank shaft teeth

and cam shaft flag.

5. Check ECU.

6. Check the TDC setting /

timing setting of crankshaft;

cam shaft and HP pump.

1. Check crank sensor to flywheel air gap to be

between 0.7 to 1.3 mm; Ensure correct air gap.

2. Check sensor connections for rust dirt etc.; if

noticed ensure clean connector pins and proper

fitment.

3. Check Electrical continuity between ECU pins 15,

14 and crank sensor connector as per circuit

schematic; follow Electrical continuity check

procedure. Replace/ Rectify Harness if required.

4. Check crank shaft teeth and cam shaft gear hole;

Replace sensor/component (flywheel/cam gear/cam

shaft) if found faulty.

5. Check ECU; if problem still persist Replace ECU.

6. After rectification test engine in following cycle

a) Start the engine; in neutral gear and press the

accelerator pedal fully (as quickly as possible)

for engine to go from Idle to fly up.

b) Stay at fly up for few seconds and suddenly

release the accelerator for the engine to come

back to idle. Repeat the above cycle 3 to 4

times and check the DTC does not reappear.
