1. Pedal reduction (P1121) is set.
2. EGR is disabled.
1. This DTC gets logged
because of Track - 1 counts
read by the sensor is more
than upper threshold.
2. Pedal connector is
removed from the sensor.
1. Check for Reference
voltage 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 2 fault (P0652;
P0653) if present; Follow Reference voltage1
(sensor supply voltage1) check rectification
Procedure to correct this fault before proceeding
further
2.Check for AD counts of the track 1 is less than 50
AD counts.???
3. Check whether the EMS ecu pin 37 is short
circuited to battery, if so rectifies the wiring harness
connections.
4. Check sensor connections for rust dirt etc.; if
noticed clean the sensor connections and ensure
proper fitment of the connector.
5. 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.
6. Visually check sensor; Replace sensor if
damaged.
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 less than 5%.
b) When the pedal is fully pressed- Pedal position
in tata diagnostic tool should be more than 95 %.

1. No critical effect
2. IMV operation under stable condition -
No trim is used for IMV operation
3. EGR is disabled.
This DTC gets logged if the
fuel temperature read by
the sensor is more than
upper threshold.
1. Check for Reference
voltage 1 fault or If P1180 is
present.
2. Check sensor connections
for rust dirt etc.
3. Check sensor
characteristics (measure
voltage and resistance at
sensor terminals).
4. Check Electrical continuity.
5. Check ECU.
1. Check sensor connections for rust dirt etc. clean
the sensor connections and ensure proper fitment.
2. Check sensor characteristics (measure voltage
and resistance at sensor terminals); Sensor voltage
should be 5 V and resistance as given in
specifications; replace sensor if found faulty.
3. Check Electrical continuity between ECU pins 71,
58 and fuel temperature sensor connector as per
circuit schematic; Follow Electrical continuity check
procedure. Replace/ Rectify Harness if required.
Check whether the EMS ecu pin 71 is short
circuited to battery. If so, then rectify the wiring
harness connections.
4. Check ECU; if problem still persists replace the
ECU.
5. After rectification if possible carry out following
check,
Soak the vehicle for more than 12 hrs. (preferably
overnight)
Then check if all the system temperature values
(coolant; fuel; inlet air) are close to each other.
