Title: A25A-FKS (ENGINE CONTROL): SFI SYSTEM: P06AB11,P06AB15; Control Module Internal Temperature Sensor "B" Circuit Short to Ground; 2018 - 2024 MY Camry [06/2017 -        ]

DTC

P06AB11

Control Module Internal Temperature Sensor "B" Circuit Short to Ground

DTC

P06AB15

Control Module Internal Temperature Sensor "B" Circuit Short to Battery or Open

DESCRIPTION

The ECM has a built-in internal temperature sensor which detects the internal temperature of the ECM. The resistance of the thermistor within the ECM internal temperature sensor changes according to the internal temperature of the ECM. The resistance of the thermistor increases as the ECM internal temperature decreases and decreases as the ECM internal temperature increases.

DTC No.

P06AB11

Control Module Internal Temperature Sensor "B" Circuit Short to Ground

The ECM internal temperature sensor output voltage is less than 0.22 V for 3 seconds or more (1 trip detection logic).

P06AB15

Control Module Internal Temperature Sensor "B" Circuit Short to Battery or Open

The ECM internal temperature sensor output voltage is higher than 4.91 V for 3 seconds or more (1 trip detection logic).

  • SAE Code: P06AE
  • DTC for Mexico Models: Does not apply

MONITOR DESCRIPTION

The ECM calculates the internal temperature of the ECM based on the output voltage of the ECM internal temperature sensor. If the output voltage of the ECM internal temperature sensor is not within the normal operating range, the ECM will illuminate the MIL and store a DTC. In this case, the ECM internal temperature sensor may be malfunctioning or there may be an open or short in the sensor circuit.

Example:

When the output voltage of the ECM internal temperature sensor is less than 0.22 V, or more than 4.91 V for 3 seconds or more, the ECM illuminates the MIL and stores a 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 2018 - 2024 MY Camry [03/2017 -        ]; A25A-FKS (ENGINE CONTROL): SFI SYSTEM: DTC CHECK / CLEAR

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

    Click here 2018 - 2024 MY Camry [03/2017 -        ]; A25A-FKS (ENGINE CONTROL): SFI SYSTEM: DTC CHECK / CLEAR

  1. Connect the Techstream to the DLC3.
  2. Turn the ignition switch is to ON.
  3. Turn the Techstream on.
  4. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
  5. Turn the ignition switch off and wait for at least 30 seconds.
  6. Turn the ignition switch to ON [A].
  7. Turn the Techstream on.
  8. Wait 5 seconds [B].
  9. Enter the following menus: Powertrain / Engine / Trouble Codes [C].
  10. 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.
  11. Enter the following menus: Powertrain / Engine / Utility / All Readiness.
  12. Input the DTC: P06AB11 or P06AB15.
  13. 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 has a malfunction.
    • [A] to [C]: 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 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

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.

CLEAR DTC

(a) Connect the Techstream to the DLC3.

(b) Turn the ignition switch to ON.

(c) Turn the Techstream on.

(d) Clear the DTCs.

Powertrain > Engine > Clear DTCs

(e) Turn the ignition switch off and wait for at least 30 seconds.

2.

READ OUTPUT DTC (DTC P06AB11 OR P06AB15)

(a) Drive the vehicle in accordance with the driving pattern described in Confirmation Driving Pattern.

(b) Enter the following menus: Powertrain / Engine / Trouble Codes.

(c) Read the DTCs.
