DTC No. Detection Item DTC Detection Condition Trouble Area MIL Memory Note
P007A15 Charge Air Cooler Temperature Sensor Bank 1 Circuit Short to Battery or Open The output voltage from the intake air temperature sensor is higher than 4.9 V for 3 seconds or more (1 trip detection logic).
  • Open or short in intake air temperature sensor circuit

  • Intake air temperature sensor (built into No. 1 turbo pressure sensor)

  • ECM

- DTC stored SAE: P007D

Tech Tips

When a DTC is output, check the Data List item "Intake Air Temperature B1S1 (Turbo)" using the GTS.

DTC No. Intake Air Temperature B1S1 (Turbo) Malfunction
P007A15 -40°C (-40°F)
  • Short in THIM circuit to power source circuit

  • Open in THIM circuit

  • Open in EPIM circuit

If the Data List displays a normal value, the normal value may be due to a temporary recovery from the malfunction condition. Check for intermittent problems.

MONITOR DESCRIPTION

The ECM calculates the intake manifold internal temperature from the intake air temperature sensor output voltage. If the intake air temperature sensor output voltage is outside the normal range, there may be a malfunction or open or short circuit in the intake air temperature sensor. In this case, the ECM stores a DTC.

Example:

If the sensor output voltage is higher than 4.9 V for 3 seconds or more, the ECM stores DTC P007A15.

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: P007A15.

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

      *1 No. 1 Turbo Pressure Sensor
      *2 ECM
      *a

      Front view of wire harness connector

      (to No. 1 Turbo Pressure Sensor)

      Disconnect the No. 1 turbo pressure sensor connector.

    2. Connect terminals 4 (THIM) and 2 (E2) of the No. 1 turbo pressure sensor 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 B1S1 (Turbo).


      Powertrain > Engine > Data List
      Tester Display
      Intake Air Temperature B1S1 (Turbo)
    7. Read the value displayed on the GTS.

  2. CHECK HARNESS AND CONNECTOR (NO. 1 TURBO PRESSURE SENSOR - ECM)


    1. Disconnect the No. 1 turbo pressure sensor 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
      C27-4 (THIM) - C20-107 (THIM) Always Below 1 Ω
      C27-2 (E2) - C20-137 (EPIM) Always Below 1 Ω
      C27-4 (THIM) or C20-107 (THIM) - Other terminals Always 10 kΩ or higher
