P1120
Pedal sensor
track 1_supply.
No critical effect.
Accelerator Pedal sensor
track 1_supply fault.
1. Check for Reference
voltage 1 fault or If P0120 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. Follow Reference voltage 1 check and
rectification Procedure.
2. Clean the sensor connections and ensure proper
fitment.
3. Remove Intermediate connector between EMS
harness and vehicle wiring harness check for
terminal back out. Do necessary repairs reconnect
and check the fault.
4. Replace sensor if damaged.
5. Follow Electrical continuity check procedure.
Replace/ Rectify Harness if required.
6. Replace ECU; if problem still persists.

P1121
Pedal sensor
fault.
Restricted fly up.
Accelerator Pedal sensor
fault (triggers reduced
torque mode).
1. Check for pedal related
faults (like P1120; P1123;
P1220; P1223 etc.).
1. Follow rectification process for the pedal faults
present.

P1123
Pedal sensor
fault (correlation
between track 1
and 2).
H
1. Reduced torque mode is activated.
2. EGR is disabled
3. This DTC will also cause P1121 to get
registered.
1. This DTC gets logged if
the difference between
Pedal Track -1 and Pedal
Track - 2; exceed the
threshold.
2. This fault will come
because of P0122; P0123;
P0120; P0222; P0223;
Check faults P0120; P0122;
P0123; P0222; P0223.
1. Check faults P0120; P0122; P0123; P0222;
P0223; if noticed Rectify the concerned faults.
2. Check Electrical continuity between ECU to
pedal connector as per circuit schematic; Follow
Electrical continuity check procedure. Replace/
Rect
3. After rectification ensure the following checks
before handing over the vehicle to customer.
a) When pedal is not pressed - Pedal position in
tata diagnostic tool should be close to 0%.
b) When the pedal is fully pressed- Pedal position
in tata diagnostic tool should be close to 100%.

P1171
Minimum Drive
Pulse too short
(Cylinder 1).
M
1. Engine may have abnormal noise and
vibrations.
2. Disables Pilot Injection.
3. Check for cylinder 1 Injector.
4. MIL is OFF.
5. Injector learning strategy is deactivated;
MDP Updating is deactivated.
This DTC gets logged if the
Cylinder 1 Injector
correction values are less
than the minimum value.
1. Check whether I2C values
are entered in ECU.
2. Check whether I2C
entered in ECU matches with
sticker on injectors.
1. Check whether I3C values (20 digit alpha
numeric number printed on the injector) are entered
in ECU; if not enter I3C values correctly and Erase
the fault.
2. Check whether I3C entered in ECU matches with
sticker on injectors; if problem persists replace
injectors; enter I3C values and erase faults.
3. If problem still persists replace ECU.

1. Engine may have abnormal noise and
vibrations.
2. Disables Pilot Injection.
3. Check for cylinder 2 Injector.
4. MIL is OFF.
5. Injector learning strategy is deactivated;
MDP Updating is deactivated.
This DTC gets logged if the
Cylinder 2 Injector
correction values are less
than the minimum value.
1. Check whether I2C values
are entered in ECU.
2. Check whether I2C
entered in ECU matches with
sticker on injectors.
1. Check whether I3C values (20 digit alpha
numeric number printed on the injector) are entered
in ECU; if not enter I3C values correctly and Erase
the fault.
2. Check whether I3C entered in ECU matches with
sticker on injectors; if problem persists replace
injectors; enter I3C values and erase faults.
3. If problem still persists replace ECU.
