Tech Tips

When DTC P011015 is stored, the ECM enters fail-safe mode. During fail-safe mode, the intake air temperature is estimated to be 20°C (68°F) by the ECM. Fail-safe mode continues until a pass condition is detected, and the engine switch is then turned off.

DTC No. Detection Item DTC Detection Condition Trouble Area MIL Memory Note
P011015 Intake Air Temperature Sensor 1 Bank 1 Circuit Short to Battery or Open The intake air temperature sensor output voltage is higher than 4.91 V for 0.5 seconds or more (1 trip detection logic).

  • Open or short in intake air temperature sensor circuit

  • Intake air temperature sensor (mass air flow meter sub-assembly)

  • ECM

 Comes on DTC stored SAE Code: P0113

Tech Tips

When this DTC is output, check the intake air temperature in the Data List. Enter the following menus: Powertrain / Engine / Data List / Intake Air Temperature.

DTC No. Intake Air Temperature Malfunction
P011015 -40°C (-40°F)

  • Short to +B in THA circuit

  • Open in THA circuit

  • Open in E2G circuit

If the Data List values is normal it may be due to a temporary recovery from the malfunction condition. Check for intermittent problems.

MONITOR DESCRIPTION

The ECM monitors the sensor voltage and uses this value to calculate the intake air temperature. When the intake air temperature sensor output voltage deviates from the normal operating range, the ECM interprets this as a malfunction in the intake air temperature sensor circuit and stores this DTC.

Example:

If the intake air temperature sensor output voltage is higher than 4.91 V for 0.5 seconds or more, the ECM store this DTC.

MONITOR STRATEGY

Frequency of Operation Continuous

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 0.5 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: P011015.

  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.

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

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. READ VALUE USING GTS (CHECK FOR OPEN IN WIRE HARNESS)

    		 - -

    1. Disconnect the mass air flow meter sub-assembly connector.

    2. Connect terminals 4 (THA) and 2 (E2G) of the mass air flow meter sub-assembly connector on the wire harness side.

    3. Connect the GTS to the DLC3.

    4. Turn the engine switch on (IG).

    5. Turn the GTS on.

    6. Enter the following menus: Powertrain / Engine / Data List / Intake Air Temperature.


      Powertrain > Engine > Data List
      Tester Display
      Intake Air Temperature

    7. Read the value displayed on the GTS.

      Standard value
      140°C (284°F)

      Tech Tips

      Perform "Inspection After Repair" after replacing the mass air flow meter sub-assembly.

  2. CHECK HARNESS AND CONNECTOR (MASS AIR FLOW METER SUB-ASSEMBLY - ECM)


    1. Disconnect the mass air flow meter sub-assembly connector.

    2. Disconnect the ECM connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      D8-4 (THA) - D2-102 (THA) Always Below 1 Ω
      D8-2 (E2G) - D2-115 (E2G) Always Below 1 Ω
      D8-4 (THA) or D2-102 (THA) - Other terminals Always 10 kΩ or higher
