Toyota Avalon Service & Repair Manual: Engine Coolant Temperature/Engine Oil Temperature Signal Compare Failure (P012F62)​

Toyota Avalon Service & Repair Manual / Engine / A25a-fxs Engine Control / Sfi System / Engine Coolant Temperature/Engine Oil Temperature Signal Compare Failure (P012F62)


DESCRIPTION
The engine is equipped with an engine coolant temperature sensor and an engine oil temperature sensor. The engine coolant temperature sensor and engine oil temperature sensor each have a built-in thermistor. As the temperature decreases, the thermistor resistance increases and as the temperature increases, the thermistor resistance decreases. The voltages at the respective terminals of the ECM change in accordance with the changes in the resistance of the thermistors. The ECM performs control based on these voltages.

Engine Coolant Temperature/Engine Oil Temperature Signal Compare Failure​
All of the following conditions are met (2 trip detection logic):​
  • The auxiliary battery voltage is higher than 8 V.
  • 5 hours or more have elapsed since the engine stopped on the previous trip.
  • The engine oil temperature is -10°C (14°F) or higher.
  • The engine coolant temperature is -10°C (14°F) or higher.
  • The difference between the readings of the engine coolant temperature and engine oil temperature is higher than 20°C (36°F).
  • Engine coolant temperature sensor
  • Engine oil temperature sensor
  • ECM
Comes on​
DTC stored​
SAE Code: P012F​
MONITOR DESCRIPTION
After the engine has stopped for 5 hours or more, the ECM monitors the voltage of the engine coolant temperature sensor and engine oil temperature sensor. If the difference between the readings of the engine coolant temperature and engine oil temperature is higher than 20°C (36°F), the ECM determines that there is a malfunction in the engine coolant temperature sensor circuit or engine oil temperature sensor circuit, and stores a DTC and illuminates the MIL.

CONFIRMATION DRIVING PATTERN
HINT:
  • After repair has been completed, clear the DTC and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.

  • When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.

  1. Connect the Techstream to the DLC3.
  2. Turn the power switch on (IG) [A].
  3. Turn the Techstream on.
  4. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
  5. Turn the power switch off.
  6. With the engine stopped, leave the vehicle as is for 5.5 hours or more .
    [*]Turn the power switch on (IG) [C].
    [*]Turn the Techstream on.
    [*]Enter the following menus: Powertrain / Engine / Trouble Codes [D].
    [*]Read the pending DTCs.
    HINT:
    • If a pending DTC is output, the system is malfunctioning.
    • If a pending DTC is not output, perform the following procedure.
    [*]Enter the following menus: Powertrain / Engine / Utility / All Readiness.
    [*]Input the DTC: P012F62.
    [*]Check the DTC judgment result.
    Techstream Display​
    Description​
    NORMAL​
    • DTC judgment completed
    • System normal
    ABNORMAL​
    • DTC judgment completed
    • System abnormal
    INCOMPLETE​
    • DTC judgment not completed
    • Perform driving pattern after confirming DTC enabling conditions
    HINT:
    • If the judgment result is NORMAL, the system is normal.
    • If the judgment result is ABNORMAL, the system is malfunctioning.
    • If the judgment result is INCOMPLETE, perform steps through [D] again.
      [*] to [D]: Normal judgment procedure.
      The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.
      [*]When clearing the permanent DTCs, do not disconnect the cable from the auxiliary battery terminal or attempt to clear the DTCs during this procedure, as doing so will clear the universal trip and normal judgment histories.

CAUTION / NOTICE / HINT
NOTICE:
  • Vehicle Control History may be stored in the hybrid vehicle control ECU assembly if the engine is malfunctioning. Certain vehicle condition information is recorded when Vehicle Control History is stored. Reading the vehicle conditions recorded in both the Freeze Frame Data and Vehicle Control History can be useful for troubleshooting.

    (Select Powertrain in Health Check and then check the time stamp data.)
    Click here
    info_285.gif
  • If any "Engine Malfunction" Vehicle Control History item has been stored in the hybrid vehicle control ECU assembly, make sure to clear it. However, as all Vehicle Control History items are cleared simultaneously, if any Vehicle Control History items other than "Engine Malfunction" are stored, make sure to perform any troubleshooting for them before clearing Vehicle Control History.

HINT:
Read Freeze Frame Data using the Techstream. The ECM records vehicle and driving condition information as Freeze Frame Data the moment a DTC is stored. When troubleshooting, Freeze Frame Data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
PROCEDURE
1.​
CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P012F62)
(a) Connect the Techstream to the DLC3.
(b) Turn the power switch on (IG).
(c) Turn the Techstream on.
(d) Enter the following menus: Powertrain / Engine / Trouble Codes.
(e) Read the DTCs and record the Freeze Frame Data.
Powertrain > Engine > Trouble Codes
Result​
Proceed to​
DTC P012F62 is output​
A​
DTC P012F62 and other DTCs are output​
B​
HINT:
If any DTCs other than P012F62 are output, troubleshoot those DTCs first.

CHECK FREEZE FRAME DATA (COOLANT TEMPERATURE AND INTAKE AIR TEMPERATURE)
(a) Connect the Techstream to the DLC3.
(b) Turn the power switch on (IG).
(c) Turn the Techstream on.
(d) Using the Techstream, read the values displayed in the Freeze Frame Data recorded in step 1.
Powertrain > Engine > DTC(P012F62) > Freeze Frame Data

Coolant Temperature​
Intake Air Temperature​
(e) Read the value displayed on the Techstream.
Standard:
Techstream Display​
Specified Condition​
Difference between the Coolant Temperature and the Intake Air Temperature​
Within 15°C (27°F)​
HINT:
  • When the engine is cold, the value of the engine coolant temperature, engine oil temperature and intake air temperature should be approximately the same.
  • If the result is not as specified, check that there are no heat sources such as a block heater in the engine compartment.
  • Perform "Inspection After Repair" after replacing the engine coolant temperature sensor.
