Toyota Avalon (XX50) 2019-2022 Service & Repair Manual / Engine / A25a-fxs Engine Control / Sfi System / Radiator Coolant Temperature Sensor Signal Compare Failure (P00B162).

Radiator Coolant Temperature Sensor Signal Compare Failure (P00B162)

DESCRIPTION

This engine uses a No. 2 engine coolant temperature sensor and an intake air temperature sensor to detect temperatures related to engine operation. A thermistor, whose resistance value varies according to the temperature, is built into each sensor. When the temperature becomes low, the resistance of the thermistor increases. When the temperature becomes high, the resistance decreases. These variations in resistance are transmitted to the ECM as voltage changes.

Radiator Coolant Temperature Sensor Signal Compare Failure

All of the following conditions are met (2 trip detection logic):

  • The auxiliary battery voltage is 10.5 V or higher.
  • 7 hours or more have elapsed since the power switch was turned off in the previous trip.
  • Less than 20 seconds since a cold engine start was performed.
  • The intake air temperature is -10°C (14°F) or higher.
  • The difference between the readings of the No. 2 engine coolant temperature and intake air temperature is higher than 25°C (45°F).
  • Intake air temperature sensor (mass air flow meter sub-assembly)
  • No. 2 engine coolant temperature sensor
  • ECM

SAE Code: P00B2

MONITOR DESCRIPTION

The ECM monitors the difference between the No. 2 engine coolant temperature and the intake air temperature when the engine is started cold to accurately detect the engine temperature conditions. The monitor runs when the engine is started after 7 hours or more have elapsed since the power switch was turned off in the previous trip. If the difference between the engine coolant temperature and the intake air temperature on a cold start exceeds 25°C (45°F), the ECM interprets this as a malfunction in the No. 2 engine coolant temperature sensor circuit or intake air temperature sensor circuit, illuminates the MIL and stores this DTC.

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.

    Click here

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

    Click here

  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 7.5 hours or more [B].
  7. Turn the power switch on (IG).
  8. Turn the Techstream on.
  9. Put the engine in Inspection Mode (Maintenance Mode).

    Click here

  10. Start the engine and wait 20 seconds or more [C].
  11. Enter the following menus: Powertrain / Engine / Trouble Codes [D].
  12. 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.

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.
