SAE Code:

P0713

HINT:

When this DTC is output, check the manual transaxle oil temperature sensor (temperature sensor) in the Data List. Enter the following menus: Powertrain / Engine / Data List / M/T Oil Temperature.

DTC No.

M/T Oil Temperature

Malfunction

P071015

-40°C (-40°F)

  • Short to +B in THOM circuit
  • Open in THOM circuit
  • Open in THO circuit
  • Open in E2 circuit

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

MONITOR DESCRIPTION

The ECM calculates the temperature of the MT fluid based on the voltage output by the manual transaxle oil temperature sensor (temperature sensor). If the output voltage of the manual transaxle oil temperature sensor (temperature sensor) is outside the normal range, there may be a malfunction in the manual transaxle oil temperature sensor (temperature sensor), or an open or short in the circuit. In that case, the ECM will illuminate the MIL and store a DTC.

CONFIRMATION DRIVING PATTERN

HINT:

After repairs have been completed, clear the DTCs and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.

  1. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
  2. Turn the ignition switch off and wait for at least 30 seconds.
  3. Turn the ignition switch to ON and wait for 3 seconds or more.
  4. Enter the following menus: Powertrain / Engine / Utility / All Readiness.
  5. Input the DTC: P071015.
  6. 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

    HINT:

    • 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 normal judgment procedure again.

    Front Seat Belt Pretensioners

    The front seat belt pretensioners are designed to deploy in moderate or severe frontal, near frontal collisions.

    In addition, the pretensioners operate when a side collision or a rollover accident is detected. The pretensioners operate differently depending on what types of air bags are equipped. For more details about the seat belt pretensioner operation, refer to the SRS Air Bag Deployment Criteria.
