SFI SYSTEM(w/ Canister Pump Module), Diagnostic DTC:P0106

DTC Code DTC Name
P0106 Manifold Absolute Pressure Circuit Problem

DESCRIPTION

A263608E01

The manifold absolute pressure sensor detects pressure inside the intake manifold as an absolute pressure with a built-in sensor and outputs it as voltage. Based on the voltage from the manifold absolute pressure sensor, the ECM controls the purge VSV and corrects any errors in the air fuel ratio due to change in pressure.

DTC No.

P0106

Manifold Absolute Pressure Circuit Problem

Intake manifold pressure measured after engine start drops by less than 2 kPa(abs) [15 mmHg(abs)] compared to the intake manifold pressure (atmospheric pressure) measured before engine start (2 trip detection logic).

  • Intake system

  • Manifold absolute pressure sensor

DTC stored

MONITOR DESCRIPTION

When the intake manifold pressure measured after engine start drops by less than 2 kPa(abs) [15 mmHg(abs)] compared to the intake manifold pressure (atmospheric pressure) measured before engine start, the ECM interprets this as a malfunction in the manifold absolute pressure sensor and stores DTC P0106.

MONITOR STRATEGY

Frequency of Operation

Continuous

CONFIRMATION DRIVING PATTERN

  1. Connect the GTS to the DLC3.

  2. Turn the power 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 power switch off and wait for at least 30 seconds.

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

  6. Put the engine in inspection mode (maintenance mode).

  7. Start the engine and warm it up until the engine coolant temperature reaches 73°C (163°F) or higher.

  8. Move the shift lever to N.

  9. Idle the engine for 10 seconds or more [A].

  10. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes [B].

  11. Read the pending DTCs.

    Tip:

    • 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 and ECT / Utility / All Readiness.

  13. Input the DTC: P0106.

  14. 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
    Tip:

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

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

    • If the judgment result shows INCOMPLETE or N/A, perform steps [A] and [B] again.

CAUTION / NOTICE / HINT

Tip:

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 ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P0106)

    1. Connect the GTS to the DLC3.

    2. Turn the power switch on (IG).

    3. Turn the GTS on.

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

    5. Read the DTCs.

  2. READ VALUE USING GTS (MAP)

    1. Connect the GTS to the DLC3.

    2. Turn the power switch on (IG).

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / Engine and ECT / Data List / Primary / MAP.

      MAP

    5. Read the MAP value.

    6. Put the engine in inspection mode (maintenance mode).

    7. Start the engine.

    8. Read the MAP value at idling.
