(P0116) ENGINE COOLANT TEMPERATURE SENSOR PERFORMANCE (CONTINUED)
12.
ECT SENSOR RANGE
Note: This test works best on a cold engine.
Turn the ignition on.
With the DRB III , read the ENG COOLANT TEMP value. If the vehi-
cle was allowed to sit overnight, the value should be reasonably close
to the ambient temperature.
Note: If engine coolant temperature is above 85°C (185°F), allow
the engine to cool until at least 65°C (150°F).
Start the engine.
During engine warm-up monitor the ENG COOLANT TEMP value as
well as the actual engine temperature with a thermometer. The ENG
COOLANT TEMP value in the DRB III
from start-up to operating temperature.
Note: As the engine warms to operating temperature, the actual
coolant temperature and the ENG COOLANT TEMP value in the DRB III should stay relatively close to each
other.
Did the ENG COOLANT TEMP value in the DRB III and the actual temperature stay relatively close to
each other?
Yes >> Go To 13
No >> Replace the Engine Coolant Temperature Sensor. (Refer to 7 - COOLING/ENGINE/ENGINE COOLANT
TEMP SENSOR - REMOVAL).
Perform POWERTRAIN VERIFICATION TEST - VER 2.
13.
CHECKING COOLANT THERMOSTAT OPERATION
Turn the ignition off.
Remove the thermostat.
Using the appropriate service information, perform thermostat diagnosis.
Did the thermostat open at the proper temperature and to the proper stroke?
Yes >> Go To 14
No >> Replace the thermostat. (Refer to 7 - COOLING/ENGINE/ENGINE COOLANT THERMOSTAT -
REMOVAL)
Perform POWERTRAIN VERIFICATION TEST - VER 2.

INTERMITTENT WIRING AND CONNECTORS
The condition that caused this DTC to set is currently not present. Inspect the related wiring harness for a possible
intermittent condition.
Note: Check connectors — Clean/repair as necessary. Poor pin to terminal connections can set DTCs.
Note: Check for any Technical Service Bulletins that may apply.
Using the wiring diagram/schematic as a guide, inspect the wiring and connectors specific to this DTC. Wiggle the
wires while checking for shorts and open circuits.
Were there any problems found?
Yes >> Repair as necessary.
Perform POWERTRAIN VERIFICATION TEST - VER 2.
No >> The condition that caused this DTC to set is currently not present. Inspect the related wiring harness for
a possible intermittent condition.
