Title: A25A-FXS (ENGINE CONTROL): SFI SYSTEM (w/o Canister Pump Module): P006900; Manifold Absolute Pressure - Barometric Pressure Correlation; 2019 - 2020 MY RAV4 HV [11/2018 - 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

Does not come on

DTC stored

SAE Code: P0069

MONITOR DESCRIPTION

Approximately 50 minutes after the power 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

  1. Connect the Techstream to the DLC3.
  2. Turn the power switch on (IG).
  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 and wait for at least 55 minutes.
  6. Turn the power switch on (IG).
  7. Turn the Techstream on.
  8. Enter the following menus: Powertrain / Engine / Trouble Codes.
  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.

    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.

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.

  • 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 P006900)

(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.

Powertrain > Engine > Trouble Codes

Result

Proceed to

DTC P006900 is output

A

DTC P006900 and other DTCs are output

B

HINT:

If any DTCs other than P006900 are output, troubleshoot those DTCs first.

READ VALUE USING TECHSTREAM (INTAKE MANIFOLD ABSOLUTE PRESSURE)

(a) Turn the power switch off and wait for at least 50 minutes.

(b) Connect the Techstream to the DLC3.

(c) Turn the power switch on (IG).

(d) Turn the Techstream on.

(e) Enter the following menus: Powertrain / Engine / Data List / Intake Manifold Absolute Pressure.

Powertrain > Engine > Data List

Tester Display

Intake Manifold Absolute Pressure

(f) Using the following table, determine the normal atmospheric pressure for the current altitude and temperature.

HINT:

  • Standard atmospheric pressure is approximately 101 kPa(abs) [15 psi(abs)].
  • For every 100 m (328 ft.) increase in altitude, atmospheric pressure drops by approximately 1 kPa (0.1 psi). This varies depending on the weather.

(g) Compare the value of the Data List item Intake Manifold Absolute Pressure with the actual atmospheric pressure.

Result

Proceed to

Approximately the same as the actual atmospheric pressure

A

Not approximately the same as the actual atmospheric pressure
