fault.
H
1. Reduced torque Mode activated.
1. This DTC is set as a
consequence of other pedal
related faults P 0122;
P0123; P0222; P0223;
P1123; P1223.
2. Pedal reduction (P1121)
raised if track 1; track 2 or
correlation fault is set.
1. Check for pedal related
faults (like P1120, P1123;
P1220; P1223 etc.).
1. Follow the rectification procedure of P 0122;
P0123; P0222; P0223; P1123; P1223; whichever is
present.P1121 will vanish once all these DTC's are
taken care of.

“B” Circuit Low.
H
1. Track 2 signal is lower than 25 AD
counts.
2. Pedal position taken as a non-faulty track
- Track 1.
3. Pedal reduction (P1121) is set.
4. EGR is disabled.
1. This DTC gets logged if
the Track 2 counts reads by
the sensor is less than
lower threshold.
2. Pedal connector is
removed from the sensor.
1. Check for vext 1 fault or If
P1120 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 for Reference voltage 1 fault (P0642;
P0643) if present; Follow Reference voltage2
(sensor supply voltage1) check and rectification
Procedure; to correct this fault before proceeding
further.
2. Check the pedal connector connected to the
pedal sensor/ module.
3. Check sensor connections for rust dirt etc.; clean
the sensor connections and ensure proper fitment.
4. Check Intermediate connector; Remove
Intermediate connector between EMS harness and
vehicle wiring harness. Check for terminal back out.
Do necessary repairs reconnect and check the
fault.
5. Visually check sensor; Replace sensor if
damaged.
6. Check Electrical continuity between ECU pins 76,
38 & 59 and pedal connector as per circuit
schematic; Follow Electrical continuity check
procedure. Rectify the wiring harness connections if
any discontinuity is found. Check whether the EMS
ecu pin 38 is short circuited to ground. If so rectify
the wiring harness connections.
7. Check ECU; if problem still persists replace ECU.
8. 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%.

fault.
H
No critical effect.
This DTC gets logged due
to fault registered in the AD
convertor in the ECU.
1. Check for pedal related
faults (like P1120; P1123;
P1220; P1223 etc.).
1. Check by erasing the fault once or twice.
2. If the problem keeps on repeating replace ECU.
