Circuit Short to Ground
ECU detects Engine coolant
temperature sensor circuit high if the
detected coolant temperature is less
than the refferenced minimum coolant
temperature value due to Sensor signal
pin short circuit to GND.
EMS ECU takes following
recovery actions:
1.
Doesn't activated AC compressor
request even though AC request
input is activated by customer and
applies default ac torque.
2.
Disables the AMF sensor learning.
3.
Disables the AMF plausibility test.
4.
Disables DTI ISO leak test, DTI
ISO IMV test & DTI HPV ISO test.
5.
Disables PWC strategy (Pilot main
waves compensation).
6.
Applies reduce torque mode:(80%
of torque).
7.
Disables SPC (Speed Pilot
Control) strategy, no more SPC
(Speed Pilot Control) trim update.
1.
Check Sensor connector. If removed then refit the connector.
2.
Check continuity between ECU pins A45 and A09 to coolant
temperature sensor connector pins 2 & 1 respectively and
rectify wiring harness if any short circuit to ground is found.
Check ECU pins and connector pins for damage/rust. In case
of rust then clean them and refit the connector.
3.
Clean the sensor connections and ensure proper fitment.
4.
Check Sensor Characteristics (measure voltage and resistance
at sensor terminals) Sensor voltage should be 5 V and
resistance as given is specifications(Sensor resistance: 1510
ohms at 35 degrees temperature); Replace sensor if found
faulty
5.
Check ECU; Replace ECU; if problem still persists.
6.
After rectification if possible carry out following check
a)Soak the vehicle for more than 12 hrs (preferably overnight)
b)Then check if all the system temperature values (coolant,
fuel, inlet air) are close to each other.

Circuit Short To Battery or
Open
ECU detects Engine coolant
temperature sensor circuit high if the
detected coolant temperature is upper
than the refferenced maximum coolant
