ATA OIL TEMPERATURE SENSOR – DIAGNOSTIC TROUBLE CODES P0711, P0712 & P0713 | Date
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:
- Using a Hi-Scan Pro or GDS, select the “Automatic Transaxle” menu and “Diagnostic Trouble Codes”. Record the DTC and description.
- 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 |
|
| ATF hot |
|
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.
- 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.
- 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:
- Drain the ATF.
- Remove all except 2 bolts to the oil pan. Loosen the remaining 2 bolts 1/8~1/4 inch.
- Use a rubber hammer to tap the oil pan at the corner until the pan separates from the case.
- Remove the 3 bolts that retain the oil filter and remove the oil filter.
- Remove the 14 mm nut and remove the manual valve lever.
- Press the tab and disconnect the fluid temperature sensor from the solenoid connector.
- Remove the bolts that secure the valve body and carefully lower the valve body.
CAUTION: The accumulators and springs may fall out of the transaxle case.
- 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.
- Remove the C-clip from the solenoid connector and remove the fluid temperature sensor.
- Install a new temperature sensor and insert the c-clip.
- Apply assembly lube and install two o-rings in the locations shown.
NOTE: The o-rings are available in 45010-23A01, ATA overhaul seal kit.
- 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.
| 1 | 2 | 1 |
| 1 spring | 2 springs | 1 spring |
- Install the yellow springs in the location shown.
- Install the 2 white springs in the location shown:
- Install the valve body and torque the bolts to specification.
Torque: 7~8 lb-ft (100~120 kgf.cm)
| Bolt | Qty. | Length | Color |
| A | 17 | 6×30 mm | Brass |
| B | 1 | 6×35 mm | Silver |
| C | 1 | 6×40 mm | Black |
| D | 1 | 6×55 mm | Brass |
| E | 1 | 6×60 mm | Silver |
- Confirm the manual valve is inserted into the slot.
- Install the manual valve lever to the manual valve and torque the nut to specification.
Torque: 7~8 lb-ft (100~120 kgf.cm)
- Reconnect the fluid temperature sensor connector to the solenoid harness connector.
- Install the o-ring on the oil filter.
- Install three magnets on the oil filter.
- Install the oil filter with 3 bolts and torque to specification.
Torque: 7~8 lb-ft, 100~120 kgf.cm)
- Apply Permatex Ultra Gray Sealer or Hyundai
Ultra Gray Gasket Sealer, P/N 00231-13800 to the oil pan and reinstall the cover. Tighten the bolts to specification.
Ultra Gray Gasket Sealer, P/N 00231-13800 to the oil pan and reinstall the cover. Tighten the bolts to specification.Torque: 6-7 lb.ft (80-100 kgf.cm).
- Add approximately 4.5 quarts of Hyundai SPIII ATF and check the level with the engine idling in Neutral or Park. Recheck the ATF level when the ATF is at normal operating temperature (75-100°C, 168-212°F).
- Clear the codes and test drive the vehicle for two driving cycles (two key-on to keyoff driving cycles, including 1-2-3-4 upshifts and 4-3-2-1 downshifts). If the DTC returns, perform the following repairs:
| DTC | REPAIR PROCEDURE |
| P0711, A/T temperature sensor – rationality check | • Exchange known-good PCM.
• Repair or replace ECM control harness. |
| P0712, A/T temperature sensor – short circuit | |
| P0713, A/T temperature sensor – open circuit | |
| P0700, TCU request for MIL on | • Delete code |
