STATUS

P0115

Engine Coolant

Temperature

Sensor 1 Circuit.

1. MIL is ON.

2. Radiator fans (Fan 1 & 2) running at full

speed.

3. Restricted performance.

4. Reduced torque Mode activated.

5. EGR is Disabled.

6. Injector learning strategy is deactivated;

(MDP Updating is deactivated).

7. System coolant temperature slowly

moves to recovery value of 80 deg.

8. AC is deactivated.

This DTC gets logged if any

of the following P-codes are

logged P0116; P0117;

P0118; P0119;

1. Check for the presence of

fault codes P1115; P0117;

P0118.

2. Check Sensor connection.

(Coolant temperature sensor

is located on UCL-elbow next

to vacuum pump).

3. Check Sensor

Characteristics (measure

voltage and resistance at

sensor terminals).

4. Check ECU.

1. Check for the presence of fault codes P1115;

P0117; P0118 if present Follow rectification process

for fault codes P1115; P0117; P0118.

2. Check Sensor connection, if not fitted properly,

correct it.

3. Ensure continuity between ECU and coolant

temperature sensor connector as per circuit

schematic.

4. Clean the sensor connections and ensure proper

fitment

5. 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

6. Check ECU; Replace ECU; if problem still

persists.

7. 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.

P0117

Engine Coolant

Temperature

Sensor 1 Circuit

Low.

1. MIL is ON.

2. Radiator fans (Fan 1 & 2) running at full

speed.

3. Restricted performance.

4. Reduced torque Mode.

5. EGR is Disabled.

6. Injector learning strategy is deactivated;

(MDP Updating is deactivated).

7. System coolant temperature slowly

moves to recovery value of 80 deg.

8. Ac is deactivated.

9. This DTC will also set P0115 - Coolant

temp fault.

This DTC gets logged if the

coolant temperature read

by the sensor is less than

lower threshold.

1. Check for Reference

voltage 1 fault or If P0115 is

present.

2. Check sensor connections

for rust dirt etc. (Coolant

temperature sensor is

located on UCL-elbow next

to vacuum pump).

3. Check sensor

characteristics (measure

voltage and resistance at

sensor terminals).

4. Check Electrical continuity.

5. Check ECU.

1. Check for Reference voltage 1 fault or If P0115 is

present; Follow Reference voltage 1 check and

rectification Procedure. Use P0115 rectification

procedure if P0115 is present.

2. Check sensor connections for rust dirt etc. clean

the sensor connections and ensure proper fitment.

3. Check whether the EMS ecu pin 72 is short

circuited to ground. If short circuit is found then

rectify the wiring harness connections.

4. Check Sensor connection, if not fitted properly,

correct it.

5. Check sensor characteristics (measure voltage

and resistance at sensor terminals). Sensor voltage

should be 5V and resistance as given is

specifications. Replace sensor if found faulty.
