STATUS

P0372

Timing

Reference High

Resolution

Signal “A” Too

Few Pulses.

1. Engine does not start.

2. Engine vibrates at certain speeds.

This DTC gets logged due

to loss of missing tooth in

the flywheel at the

expected place.

In other words; If two

consecutive crank events

(2 missing teeth) occur too

far from the previous one

detected,

1. Noise signal in the crank

sensor signal path.

2. Under excessive engine

declaration can cause the

fault.

Normal engine declaration

is taken in to account

before raising this fault.

Numbers of missing 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 Target.

5. Check ECU.

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.

P0500

Vehicle Speed

Sensor “A”.

1. Possibly No ODO/Speedo Display.

2. Signal loss from Odometer to ECU.

3. EGR is disabled

4. Injector learning strategy is deactivated;

MDP Updating is deactivated

5. Reduced torque mode [Restricted

performance].

This DTC gets logged as a

result of P0501; P0503. so

follow rectification process

of P050;P0503 whichever

is present.

A. For Non-ABS vehicle.

1. Confirm vehicle speed is

displayed in dash board. If

not check continuity from

Vehicle speed sensor to

dashboard.

2. Check Vehicle speed

sensor.

3. Check dashboard cluster.

4. Check intermediate

connector for continuity.

5. Check connector pins for

rust; dirt formation etc. ~B.

For ABS vehicles check for

ABS ECU related Faults.

This DTC gets logged as a result of P0501; P0503.

So follow rectification process of P0501; P0503

whichever is present

1. Check and confirm vehicle speed is displayed in

dash board. If not check continuity from Vehicle

speed sensor to dashboard.

2. Check Vehicle speed sensor availability /

damage; Replace Vehicle speed sensor if faulty.

3. Check continuity between dashboard clusters to

ECU pins 33, 59 as per circuit diagram.

4. Check dashboard cluster; rectify Dashboard

cluster if faulty.

5. Check intermediate connector for continuity;

Repair/ rectify the connectors.

6. Check connector pins for rust; dirt formation etc.

clean the connectors to remove rust etc.

7. Check ECU; Replace ECU if problem still

persists.

8. Final check for reconfirmation drive the vehicle at

from 0 to 100 kmph and cross check the vehicle

speed shown by ECU against speedo meter; the

readings should be close to each other.
