OCTOBER, 2007

  Model      2007~ ELANTRA

 

This TSB requires Kent-Moore J-36850-A Transmission Assembly Lube (Available at 800-345-2233).

 

DESCRIPTION:

Incorrect operation of the oil temperature sensor may result in the following symptoms:

  • “Check Engine” Light illuminated
  • Diagnostic Trouble Codes as shown below:
DTC DESCRIPTION 2007 ELANTRA SHOP MANUAL
P0711 A/T temperature sensor – rationality check AT-41
P0712 A/T temperature sensor – short circuit AT-47
P0713 A/T temperature sensor – open circuit AT-50

 

NOTE:  Do NOT replace the transaxle if these fluid temperature sensor codes are active.  Instead, follow the repair procedure shown below.

 

REPAIR PROCEDURE:

  1. Using a Hi-Scan Pro or GDS, select the “Automatic Transaxle” menu and “Diagnostic Trouble Codes”. Record the DTC and description.
  2. Using a Hi-Scan Pro or GDS, select: ”Automatic Transaxle”, “Current Data” and “Fluid Temperature Sensor”. Check the fluid temperature readout. The continuity of the wiring harness is good if the GDS or Scan tool reads as shown below:
    • If so, go to Step 4.
    • If not, go to Step 3.
ATF TEMPERATURE GDS or Scan tool readout
ATF cold
  • Same as outside temperature
  • Not stuck at 80°C (176°F)
ATF hot
  • 158-212°F (70-100°C)
  • Not stuck at 80°C (176°F)

 

NOTE:  This test confirms the wiring harness does not have an open or short circuit. It does not confirm the proper functioning of the fluid temperature sensor under all conditions of heat and vibration or an intermittent open/ short condition.

  1. If Step 2 shows improper continuity, the harness or fluid temperature sensor may have an open or short to ground. Perform the following:
    • Visually check the wiring harness between the PCM and transaxle for a damaged wire or a short circuit to ground.
    • Disconnect the connectors at the transaxle and the PCM and check for a bent pin or a pin not fully inserted into the connector. Check the pin tension using the J-35616-C Pin Tension Tester.
    • Follow the procedure in the 2007 Elantra Shop Manual, Pages AT-41~42 and check the power supply to the harness connector.
    • If a harness open/short is found, repair or replace the ECM control harness between the PCM and transaxle, P/N 91410-2H***. Go to Step 28.
    • If no harness open/short is found, go to Step 4.
  2. Refer to the DTC recorded in Step 1 and follow the repair procedure shown below:
DTC 2007 ELANTRA SHOP MANUAL REPAIR PROCEDURE
P0711, A/T temperature sensor – rationality check Replace fluid temperature sensor.
P0712, A/T temperature sensor circuit – low Replace fluid temperature sensor.
P0713, A/T temperature sensor circuit – low Replace fluid temperature sensor.
P0700 (TCU request for MIL on) Delete code

 

FLUID TEMPERATURE SENSOR REPLACEMENT PROCEDURE:

  1. Drain the ATF.
  1. Remove all except 2 bolts to the oil pan. Loosen the remaining 2 bolts  1/8~1/4 inch.
  2. Use a rubber hammer to tap the oil pan at the corner until the pan separates from the case.

  1. Carefully lay the valve body on a clean paper towel.

CAUTION:  Do not use a shop rag. Cloth rags contain lint that may cause a valve to stick in the valve body.

 

  1. Remove the C-clip from the solenoid connector and remove the fluid temperature sensor.

  1. Apply Kent-Moore Assembly Lube, P/N J-36850-A (available at 800345-2233) to the accumulator and bore in the case.

CAUTION: Other assembly lube products may not hold the accumulators in place during assembly.

NOTE: An assistant may be required to hold the accumulators in place until the valve body is installed in the case.
