DTC detection condition
P019600EOT SENSOR
(Engine oil temperature sensor A range/performance)
ADiagnosis condition—
Signal (terminal)Engine oil temperature sensor signal
ThresholdRationally incorrect voltage from the sensor is sent to ECM, compared with the voltage signals from EOT sensor and intake air temperature sensor
Diagnosis delay time—
BDiagnosis condition—
Signal (terminal)Engine cold start
ThresholdThe comparison result of signals transmitted to ECM from each temperature sensor (IAT sensor, ECT sensor, FTT sensor, and EOT sensor) shows that the signal voltage of the EOT sensor is higher/lower than that of other temperature sensors when the engine is started with its cold state
Diagnosis delay time—
 
 
POSSIBLE CAUSE
 
 
Malfunction A
  • Harness or connectors (EOT sensor circuit is open or shorted.)
  • Engine oil temperature sensor
 
 
Malfunction B
  • Harness or connectors (High or low resistance in EOT sensor circuit)
  • Engine oil temperature sensor
 
 
FAIL-SAFE
Not applicable
 
 
DTC Confirmation Procedure
1.CHECK DTC PRIORITY
If DTC P0196 is displayed with DTC P0197 or P0198, first perform the trouble diagnosis for DTC P0197 or P0198.
Is applicable DTC detected?
Perform diagnosis of applicable.
.
 
2.INSPECTION START
Is it necessary to erase permanent DTC?
.
.
 
3.PRECONDITIONING
If DTC CONFIRMATION PROCEDURE has been previously conducted, always perform the following procedure before conducting the next test.
  1. Turn ignition switch OFF and wait at least 10 seconds.
  2. Turn ignition switch ON.
  3. Turn ignition switch OFF and wait at least 10 seconds.
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is 11 V or more at idle.

4.PERFORM DTC CONFIRMATION PROCEDURE FOR MALFUNCTION A-1
  1. Start engine and warm it up to normal operating temperature.
  2. Turn ignition switch OFF and wait at least 10 seconds.
  3. Turn ignition switch ON.
  4. Turn ignition switch OFF and wait at least 10 seconds.
  5. Start engine and let it idle for 5 minutes and 10 seconds.
  6. Check 1st trip DTC.
Is 1st trip DTC detected?
Proceed to DTC Diagnosis Procedure.

5.PERFORM DTC CONFIRMATION PROCEDURE FOR MALFUNCTION A-2
With M.U.T.-III SE
  1. Select “DATA MONITOR” mode of “ENGINE” using M.U.T.-III SE.
  2. Check that “COOLANT TEMP/S indicates above 80°C (176°F).
    If it is above 80°C (176°F), go to the following steps.
    If it is below 80°C (176°F), warm engine up until “COOLANT TEMP/S” indicates more than 80°C (176°F). Then perform the following steps.
  3. Turn ignition switch OFF and soak the vehicle in a cool place.
  4. Turn ignition switch ON.
    noteDo not turn ignition switch OFF until step 9.
  5. Select “DATA MONITOR” mode of “ENGINE” using M.U.T.-III SE.
  6. Check the following.
    COOLANT TEMP/SBelow 40°C (104°F)
    INT/A TEMP SEBelow 40°C (104°F)
    Difference between “COOLANT TEMP/S” and “INT/A TEMP SE”Within 6°C (11°F)
    If they are within the specified range, perform the following steps.
    If they are out of the specified range, soak the vehicle to meet the above conditions. Then perform the following steps.
    note
    • Do not turn ignition switch OFF.
    • If it is supposed to need a long period of time, do not deplete the battery.
  7. Start engine and let it idle for 5 minutes.
  8. Check 1st trip DTC.
 
With GST
Follow the procedure “With M.U.T.-III SE” above.
 
Is 1st trip DTC detected?
Proceed to DTC Diagnosis Procedure.
.
 
6.PERFORM COMPONENT FUNCTION CHECK (FOR MALFUNCTION B)
Perform component function check. Refer to Component Inspection.
noteUse the component function check to check the overall function of the EOT sensor circuit. During this check, a 1st trip DTC might not be confirmed.
Is the inspection result normal?
-1To check malfunction symptom before repair: Refer to Intermittent IncidentIntermittent Incident.
-2Confirmation after repair: INSPECTION END
Proceed to DTC Diagnosis Procedure.
 
7.PRECONDITIONING
If DTC CONFIRMATION PROCEDURE has been previously conducted, always perform the following procedure before conducting the next test.
  1. Turn ignition switch OFF and wait at least 10 seconds.
  2. Turn ignition switch ON.
  3. Turn ignition switch OFF and wait at least 10 seconds.
TESTING CONDITION:
  • Before performing the following procedure, do not add fuel.
  • Before performing the following procedure, check that fuel level is between 1/4 and 4/4.
  • Before performing the following procedure, confirm that battery voltage is 11 V or more at idle.

8.PERFORM DTC CONFIRMATION PROCEDURE B
  1. Move the vehicle to a cool place.
    noteCool the vehicle in an environment of ambient air temperature between −10°C (14°F) and 35°C (95°F).
  2. Turn ignition switch OFF and leave the vehicle for 12 hours.
    cautionNever turn ignition switch ON during this procedure.
    noteThe vehicle must be cooled with the hood open.
  3. Start engine and let it idle for 5 minutes or more.
    cautionNever turn ignition switch OFF during idling.
  4. Check 1st trip DTC.
Is 1st trip DTC detected?
Proceed to DTC Diagnosis Procedure.
-1To check malfunction symptom before repair: Refer to Intermittent IncidentIntermittent Incident.
-2Confirmation after repair: INSPECTION END
