Title: A25A-FXS (ENGINE CONTROL): SFI SYSTEM (w/ Canister Pump Module): P006900; Manifold Absolute Pressure - Barometric Pressure Correlation; 2020 MY RAV4 RAV4 HV [06/2020 - 08/2020]

DTC

P006900

Manifold Absolute Pressure - Barometric Pressure Correlation

DESCRIPTION

The manifold absolute pressure sensor installed to the intake manifold detects the intake manifold pressure using a built-in sensor.

An atmospheric pressure sensor is built into the ECM. When the engine is stopped, the value of the manifold absolute pressure sensor and atmospheric pressure sensor will be approximately the same as the atmospheric pressure.

DTC No.

Note

P006900

Manifold Absolute Pressure - Barometric Pressure Correlation

Difference between atmospheric pressure value of the absolute pressure sensor and atmospheric pressure sensor is higher than threshold value (2 trip detection logic).

  • Manifold absolute pressure sensor
  • ECM

Comes on

DTC stored

SAE Code: P0069

MONITOR DESCRIPTION

Approximately 50 minutes after the ignition switch is turned off, the soak timer is activated and the values of the manifold absolute pressure sensor and atmospheric pressure sensor are compared. If the difference between the values of the manifold absolute pressure sensor and atmospheric pressure sensor is higher than a threshold value in consecutive driving cycles, the ECM will store 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.

  1. Connect the Techstream to the DLC3.
  2. Turn the ignition switch 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 55 minutes [A].
  6. Turn the ignition switch to ON [B].
  7. Turn the Techstream on.
  8. Enter the following menus: Powertrain / Engine / Trouble Codes [C].
  9. 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.
  10. Enter the following menus: Powertrain / Engine / Utility / All Readiness.
  11. Input the DTC: P006900.
  12. 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 shows NORMAL, the system is normal.
    • If the judgment result shows ABNORMAL, the system is malfunctioning.
    • [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 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.

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.

CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P006900)

(a) Connect the Techstream to the DLC3.

(b) Turn the ignition switch to ON.

(c) Turn the Techstream on.

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

(e) Read the DTCs.
