SFI SYSTEM(w/o Canister Pump Module), Diagnostic DTC:P222611, P222615

DTC Code DTC Name
P222611 Barometric Pressure Sensor "A" Circuit Short to Ground
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. Detection Item DTC Detection Condition Trouble Area MIL Memory Note
P222611 Barometric Pressure Sensor "A" Circuit Short to Ground Open or short in atmospheric pressure sensor circuit (ECM internal malfunction) (1 trip detection logic). ECM Comes on DTC stored SAE Code: P2228
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

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


  1. Connect the GTS to the DLC3.

  2. Turn the engine switch on (IG) and turn the GTS on.

  3. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).

  4. Turn the engine switch off and wait for at least 30 seconds.

  5. Turn the engine switch on (IG) and turn the GTS on.

  6. Wait 5 seconds or more.

  7. Enter the following menus: Powertrain / Engine / Trouble Codes.

  8. Read the pending DTCs.

    Tech Tips


    • If a pending DTC is output, the system is malfunctioning.

    • If a pending DTC is not output, perform the following procedure.

  9. Enter the following menus: Powertrain / Engine / Utility / All Readiness.

  10. Input the DTC: P222611 or P222615.

  11. 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

    N/A
    • Unable to perform DTC judgment

    • Number of DTCs which do not fulfill DTC preconditions has reached ECU memory limit

    Tech Tips


    • If the judgment result shows NORMAL, the system is normal.

    • If the judgment result shows ABNORMAL, the system has a malfunction.

CAUTION / NOTICE / HINT

Tech Tips

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


  1. CHECK DTC OUTPUT


    1. Connect the GTS to the DLC3

    2. Turn the engine switch on (IG).

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / Engine / Trouble Codes.

    5. Read the DTCs.
