This bulletin provides information related to replacing the transaxle oil temperature sensor on six-speed automatic transaxles with DTC P0711, P0712 and/or P0713. This includes 2011 and later Sorento (Xma), Sorento (VQ), Sportage (SL), Optima (TF/QF; excluding HEV), Forte (TD), and 2012 and later Rio (UB) and Soul (AM) vehicles.

NOTE: This procedure is to be performed after performing the DTC diagnostics as shown on the KGIS website. The technician must perform both wire harness and component inspections prior to performing this TSB.

DTC INFORMATION (all require sensor replacement)


P0712……..Circuit low

P0713……..Circuit high

  1. Connect the GDS to the vehicle. Turn the ignition ON with engine OFF. Navigate to the A/T menu and check for DTCs. Record any DTC and freeze frame data if available on the back of the repair order. Delete any DTCs.
  2. From the GDS, select Data Analysis and Oil Temperature. Drive the vehicle and monitor the oil temperature sensor. Record observations on the repair order.
  3. Check the wiring harness between the TCM and transaxle visually for a damaged wire or connector.
  4. Refer to the DTC recorded in Step 1 and follow the repair procedure.
  5. Record the customer’s audio presets. Disconnect the battery. Remove the lower splash shield.
  6. Drain the ATF and replace the transaxle drain plug gasket P/N 21513 11000 upon reinstallation of the drain plug. Tighten the drain plug to 25-3 – 32.6 ft.-lbs.
  7. Disconnect the breather tube from the valve body cover. Remove the hose clamp and disconnect the breather tube from the plastic nipple. Use care, as nipple damage will require valve body cover replacement.
  8. Remove the valve body cover. Detailed removal/installation steps vary depending on model. The valve body cover can be removed from all models listed in this TSB without removing the transaxle from the vehicle. Note that tightening torque fro the cover is 7.2 – 8.7 ft.-lbs. NOTE: For a plastic cover, do not lose the rubber gasket. Re-use rubber gaskets on plastic valve body covers. For metal covers, use liquid sealant UM010 CH046 or equivalent. Apply liquid gasket (to clean surfaces) at application points at the valve body cover with a 2.5 mm (0.0984-in.) bead.
  9. Locate the transaxle temperature sensor.
  10. Use a flat-blade screwdriver to disconnect the wire harness from the transaxle temperature sensor. NOTE: Use caution not to damage the wire harness. Damage to the wire harness will require replacement and transaxle removal to replace the ribbon cable.
  11. Remove the transaxle temperature sensor (secured with a single bolt). Replace with a new sensor, tighten the mounting bolt to 7.2 – 8.7 ft.-lbs. and re-connect the harness to the sensor.
  12. Install components in reverse order. Connect the battery cable and re-program audio presets. Re-fill the transaxle using 5 quarts of genuine Kia ATF. Perform a fluid level check with the fluid at an operating temperature of 122 – 140 degrees Fahrenheit.
