Title: A25A-FKS (ENGINE CONTROL): SFI SYSTEM: P222611,P222615; Barometric Pressure Sensor "A" Circuit Short to Ground; 2018 - 2024 MY Camry [06/2017 -        ]

DTC

P222611

Barometric Pressure Sensor "A" Circuit Short to Ground

DTC

P222615

Barometric Pressure Sensor "A" Circuit Short to Battery or Open

DESCRIPTION

The atmospheric pressure sensor is built into the ECM. The ECM provides optimal control in response to atmospheric pressure fluctuations.

DTC No.

P222611

Barometric Pressure Sensor "A" Circuit Short to Ground

Short in atmospheric pressure sensor circuit (ECM internal malfunction) (1 trip detection logic).

ECM

  • SAE Code: P2228
  • DTC for Mexico Models: Applies

P222615

Barometric Pressure Sensor "A" Circuit Short to Battery or Open

Open or short in atmospheric pressure sensor circuit (ECM internal malfunction) (1 trip detection logic).

ECM

Comes on

DTC stored

  • SAE Code: P2229
  • DTC for Mexico Models: Applies

MONITOR DESCRIPTION

The ECM calculates the atmospheric pressure from the atmospheric pressure sensor output voltage. When the atmospheric sensor assembly output voltage is outside of the normal range, there may be an open or short in the atmospheric pressure sensor circuit or the atmospheric pressure sensor may be malfunctioning. In this case, the ECM will illuminate the MIL and store 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 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.
  7. Turn the Techstream on.
  8. Wait 5 seconds or more [A].
  9. Enter the following menus: Powertrain / Engine / Trouble Codes [B].
  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: P222611 or P222615.
  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 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.

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.

CHECK DTC OUTPUT

(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.

Powertrain > Engine > Trouble Codes
