Title: A25A-FXS (ENGINE CONTROL): SFI SYSTEM (w/o Canister Pump Module): P010511; Manifold Absolute Pressure / Barometric Pressure Sensor Circuit Short to Ground; 2019 - 2020 MY RAV4 HV [11/2018 - 08/2020]

DTC

P010511

Manifold Absolute Pressure / Barometric Pressure Sensor Circuit Short to Ground

DESCRIPTION

The manifold absolute pressure sensor detects the intake manifold pressure as a change in voltage. The ECM calculates the intake manifold pressure based on this voltage. The ECM calculates the EGR valve assembly and purge VSV opening amount according to changes in the intake manifold pressure and also detects malfunctions of the manifold absolute pressure sensor using these changes in pressure.

DTC No.

Note

P010511

Manifold Absolute Pressure / Barometric Pressure Sensor Circuit Short to Ground

The manifold absolute pressure sensor output voltage is less than 0.5 V for 0.5 seconds or more (1 trip detection logic).

  • Open or short in manifold absolute pressure sensor circuit
  • Manifold absolute pressure sensor

DTC stored

SAE Code: P0107

HINT:

When this DTC is output, check the intake manifold absolute pressure in the Data List. Enter the following menus: Powertrain / Engine / Data List / Intake Manifold Absolute Pressure.

DTC No.

Intake Manifold Absolute Pressure

Malfunction

P010511

Approximately 0 kPa (0 psi)

  • Short to ground in PIM circuit
  • Short in PIM to EPIM circuit
  • Open in VCPM circuit

If the Data List value is normal it may be due to a temporary recovery from the malfunction condition. Check for intermittent problems.

MONITOR DESCRIPTION

The ECM monitors the manifold absolute pressure sensor voltage and uses this value to calculate the intake manifold pressure. When the manifold absolute pressure sensor output voltage deviates from the normal operating range, the ECM interprets this as a malfunction in the manifold absolute pressure sensor circuit, illuminates the MIL and stores a DTC.

Example:

If the manifold absolute pressure sensor output voltage is less than 0.5 V for 0.5 seconds or more, the ECM stores 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 30 seconds.
  6. Turn the power switch on (IG).
  7. Turn the Techstream on.
  8. Put the engine in Inspection Mode (Maintenance Mode).

  9. Start the engine and wait 5 seconds or more.
  10. Enter the following menus: Powertrain / Engine / Trouble Codes.
  11. 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.
  12. Enter the following menus: Powertrain / Engine / Utility / All Readiness.
  13. Input the DTC: P010511.
  14. 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.

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.
