Title: G16E-GTS (ENGINE CONTROL): SFI SYSTEM: P010511; Manifold Absolute Pressure / Barometric Pressure Sensor Circuit Short to Ground; 2023 - 2025 MY GR Corolla [09/2022 -        ]

DTC

P010511

Manifold Absolute Pressure / Barometric Pressure Sensor Circuit Short to Ground

DESCRIPTION

The No. 1 turbo pressure sensor detects the intake manifold pressure as a change in voltage. The ECM calculates the intake manifold pressure based on this voltage.

DTC No.

Trouble Area

MIL

Note

P010511

Manifold Absolute Pressure / Barometric Pressure Sensor Circuit Short to Ground

The No. 1 turbo pressure sensor output voltage is less than 0.72 V for 3 seconds or more (1 trip detection logic).
  • Open or short in No. 1 turbo pressure sensor circuit
  • No. 1 turbo pressure sensor
  • ECM

Comes on

SAE Code: P0107

HINT:

When a DTC is output, check the Data List item "Intake Manifold Absolute Pressure" using the GTS.

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 displays a normal value, the normal value may be due to a temporary recovery from the malfunction condition. Check for intermittent problems.

MONITOR DESCRIPTION

The ECM monitors the No. 1 turbo pressure sensor voltage and uses this value to calculate the intake manifold pressure. When the No. 1 turbo pressure sensor output voltage deviates from the normal operating range, the ECM interprets this as a malfunction in the No. 1 turbo pressure sensor circuit, illuminates the MIL and stores a DTC.

Example:

If the sensor output voltage is less than 0.72 V for 3 seconds or more, the ECM 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 2023 - 2025 MY GR Corolla [09/2022 -        ]; G16E-GTS (ENGINE CONTROL): SFI SYSTEM: DTC CHECK / CLEAR

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

    Click here 2023 - 2025 MY GR Corolla [09/2022 -        ]; G16E-GTS (ENGINE CONTROL): SFI SYSTEM: DTC CHECK / CLEAR

  1. Connect the GTS to the DLC3.
  2. Turn the ignition switch to ON.
  3. Turn the GTS 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. Start the engine and wait 5 seconds or more [A].
  7. Turn the GTS on.
  8. Enter the following menus: Powertrain / Engine / Trouble Codes [B].
  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: P010511.
  12. Check the DTC judgment result.

    GTS 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.
    • [A] to [B]: 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.

WIRING DIAGRAM

CAUTION / NOTICE / HINT

HINT:

Read Freeze Frame Data using the GTS. 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

CHECK HARNESS AND CONNECTOR

HINT:

Make sure that the connector is properly connected. If it is not, securely connect it and check for DTCs again.

(a) Disconnect the No. 1 turbo pressure sensor connector.
