SFI SYSTEM, Diagnostic DTC:P010511

DTC Code DTC Name
P010511 Manifold Absolute Pressure / Barometric Pressure Sensor Circuit Short to Ground

DESCRIPTION

A001RIWE20

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. Detection Item DTC Detection Condition Trouble Area MIL Memory 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

  • ECM

 Comes on DTC stored SAE Code: P0107

Tech Tips

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 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.

MONITOR STRATEGY

Frequency of Operation Continuous

CONFIRMATION DRIVING PATTERN


  1. Connect the GTS to the DLC3.

  2. Turn the power switch on (IG).

  3. Turn the GTS 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 GTS 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.

    Tech Tips


    • 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.

    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 is NORMAL, the system is normal.

    • If the judgment result is ABNORMAL, the system is malfunctioning.

    • If the judgment result is INCOMPLETE or N/A, perform the Confirmation Driving Pattern and check the DTC judgment result again.

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 HARNESS AND CONNECTOR

    (to Manifold Absolute Pressure Sensor)

    Tech Tips

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


    1. Disconnect the manifold absolute pressure sensor connector.

    2. Turn the power switch on (IG).

    3. Measure the voltage according to the value(s) in the table below.

      Standard Voltage
      Tester Connection Switch Condition Specified Condition
      C2-3 (VC) - C2-1 (E2) Power switch on (IG) 4.75 to 5.25 V
      C2-2 (PIM) - C2-1 (E2) Power switch on (IG) 3.0 to 5.25 V

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

    5. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Switch Condition Specified Condition
      C2-3 (VC) - C2-2 (PIM) Power switch off 171 to 189 kΩ
      Result

  2. CHECK HARNESS AND CONNECTOR (MANIFOLD ABSOLUTE PRESSURE SENSOR - ECM)


    1. Disconnect the C2 manifold absolute pressure sensor connector.

    2. Disconnect the C63 ECM connector.

    3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      C2-3 (VC) - C63-77 (VCPM) Always Below 1 Ω
      C2-2 (PIM) or C63-78 (PIM) - Body ground and other terminals Always 10 kΩ or higher
      Result
