Fuel Injector (2 pin type)

DTC P0116:00

ECT sensor circuit range/performance problem
DETECTION CONDITION
•  With the following conditions met, a condition has continued for 5 min in which change in the engine coolant temperature after the fuel cut control was performed is less than 0.004 °C {0.007 °F}.
MONITORING CONDITIONS
―  Period vehicle being left: 6 h or more
―  Battery voltage: 10 V or more
―  VSS: Normal
―  The following DTCs are not detected:
•  ECT sensor: P0117:00, P0118:00
Diagnostic support note
•  This is a continuous monitor (CCM).
•  The check engine light illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM.
•  PENDING CODE is available if the PCM detects the above malfunction condition during first drive cycle.
•  FREEZE FRAME DATA/Snapshot data is available.
•  DTC is stored in the PCM memory.
FAIL-SAFE FUNCTION
•  PCM restricts engine torque.
•  Inhibits the auto diesel particulate filter regeneration control.
•  Inhibits the compulsory diesel particulate filter regeneration control.
•  Inhibits the EGR control.
•  PCM restricts engine-transaxle integration control. (ATX)
•  Increase the idle speed.
•  Inhibits the A/C control.
•  Inhibits engine-stop by operating the i-stop function.
POSSIBLE CAUSE
•  ECT sensor connector or terminals malfunction
•  PCM connector or terminals malfunction
•  ECT sensor malfunction
•  Thermostat malfunction
•  PCM malfunction

Yes
Repair or replace the connector and/or terminals, then go to Step 7.
No
Go to the next step.
4
INSPECT PCM CONNECTOR CONDITION
•  Disconnect the PCM connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
•  Is there any malfunction?
Yes
Repair or replace the connector and/or terminals, then go to Step 7.
No
Go to the next step.
5
INSPECT ECT SENSOR
•  Inspect the ECT sensor.
•  Is there any malfunction?
Yes
Replace the ECT sensor, then go to Step 7.
(See ENGINE COOLANT TEMPERATURE (ECT) SENSOR REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)
No
Go to the next step.
6
INSPECT THERMOSTAT
•  Inspect the thermostat.
•  Is there any malfunction?
Yes
Replace the thermostat, then go to the next step.
(See THERMOSTAT REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)
No
Go to the next step.
7
VERIFY DTC TROUBLESHOOTING COMPLETED
•  Always reconnect all disconnected connectors.
•  Clear the DTC from the PCM memory using the M-MDS.
•  Leave the vehicle for 6 hours or more.
•  Start the engine and idle it for 20 min.
•  Perform the Pending Trouble Code Access Procedure.
•  Is the PENDING CODE for this DTC present?
Yes
Repeat the inspection from Step 1.
•  If the malfunction recurs, replace the PCM.
Go to the next step.
No
Go to the next step.
8
VERIFY AFTER REPAIR PROCEDURE
•  Perform the “AFTER REPAIR PROCEDURE”.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
(See DTC TABLE [PCM (SKYACTIV-D 2.2)].)
No
DTC troubleshooting completed.


Fuel Injector (6 pin type)

DTC P0116:00

ECT sensor circuit range/performance problem
