    P0116 ENGINE COOLANT TEMPERATURE (ECT) SENSOR RATIONALITY

    When Monitored and Set Condition:

    When Monitored: While the engine is running.
    Set Condition: The ECM does not read a change in value from the sensor over time.

    POSSIBLE CAUSES

    • LOW COOLANT LEVEL
    • COOLANT TEMPERATURE SENSOR
    • THERMOSTAT
    • INTERMITTENT CONDITION

    DIAGNOSTIC PROCEDURE

    NOTE: Refer to VERIFICATION TESTS for appropriate verification test procedures.

    1. With the engine cold, verify the level of coolant in the radiator. Is the radiator full of coolant?
      Yes --> Go To 2
      No --> Fill the radiator with coolant- refer to the owners manual for assistance. Perform POWERTRAIN VERIFICATION TEST VER - 1 (DIESEL).
    2. Remove the temperature sensor and reconnect the wiring to the sensor. Turn the ignition on. Monitor DRBIII®, while heating the sensor with an external heat source (DO NOT USE OPEN FLAME). Does the reading from the sensor increase at least 5 degrees F. on the DRBIII®?
      Yes --> Go To 3
      No --> Replace the coolant temp sensor. Perform POWERTRAIN VERIFICATION TEST VER - 1 (DIESEL). NOTE: Refer to the Symptom: *FUEL HEATER THERMOSTAT TEST to ensure the thermostat is operating properly.
    3. Is the thermostat operating properly?
      Yes --> Refer to the SYMPTOM: INTERMITTENT CONDITION Symptom (Diagnostic Procedure). Perform POWERTRAIN VERIFICATION TEST VER - 1 (DIESEL).
      No --> Replace the Thermostat. Perform POWERTRAIN VERIFICATION TEST VER - 1 (DIESEL).
