Attach a GDS and select DTC Analysis and A/T menu. Record the DTC and description. Delete the DTC. 2. From the GDS home screen, select Data Analysis and A/T menu and the sensors shown below. If the sensors show: Continuous and changing output while driving, the wiring currently has no open/short circuits. Go to Step 4. No continuous and changing output, go to Step 3. 3. Visually check the wiring harness between the ECU and transmission for a damaged wire or open/short circuit. Check for a damaged pin or pin not fully inserted into the connector. If damage exists, repair or replace the ECU control harness and drive the vehicle to confirm the repair. If no damage or open/short circuit is found, go to Step 4. 4. Refer to the DTC recorded in Step 1 and follow the repair procedure shown below: DTC P071700 P072100 P072200 DESCRIPTION Input/turbine speed sensor A circuit no signal Output speed sensor circuit range/performance Output speed sensor circuit no signal REPAIR PROCEDURE Go to Step 5 and replace the input/output speed sensor and valve body harness. 5. Record the preset radio stations. Remove the air cleaner, battery and battery tray. 6. Remove the undercover below the transmission. Lift the vehicle on a hoist. 7. If necessary to access the sensors, drain the radiator and remove the lower radiator hose from the radiator. Drain the ATF. TSB #: 20-AT-003H Page 2 of 7 SUBJECT: 8. ATM INPUT/OUTPUT SPEED SENSOR DTC P071200, P072100 & P072200 Disconnect the harness from the transmission. Remove the bolt that secures the retainer and push the harness connector into the transmission. Disconnect the vent hose on the top of the oil pan. 9. Remove 14 oil pan bolts and remove the pan. CAUTION Use a rubber hammer to tap the oil pan cover on a corner until the cover is loose. 10. Remove 6 bolts to the harness and 1 bolt to the oil temperature sensor. Pull the harness outward and move the harness out of position. TSB #: 20-AT-003H Page 3 of 7 SUBJECT: ATM INPUT/OUTPUT SPEED SENSOR DTC P071200, P072100 & P072200 11. Remove the bolt that secures the detent spring and remove the spring. Torque: 8~11 lb.ft (1.2~1.5 kgf.m/10~13 N.m) 12. Remove 9 valve body bolts in order from the outermost bolts to the innermost bolts. Remove the valve body. CAUTION Place the valve body on a clean paper towel. Placing the valve body on a rag may cause lint to enter the valve body. 13. Pull the gray tab up and then press the tab to disconnect the harness from the input speed sensor. Remove two bolts and remove the input speed sensor. Install a new input speed sensor. Remove the harness and install a new harness. Connect the harness to the input speed sensor. Torque: 7~9 lb.ft (1.0~1.2 kgf.m/10~12 N.m) TSB #: 20-AT-003H Page 4 of 7 SUBJECT: ATM INPUT/OUTPUT SPEED SENSOR DTC P071200, P072100 & P072200 14. Confirm two O-rings are installed correctly in the case. 15. Align the manual shaft to the shift lever and install the valve body. 16. Install the valve body bolts and torque the bolts in order from the innermost bolts to the outermost bolts. Torque: 7~9 lb.ft (1.0~1.2 kgf.m/10~12 N.m) TSB #: 20-AT-003H Page 5 of 7 SUBJECT: ATM INPUT/OUTPUT SPEED SENSOR DTC P071200, P072100 & P072200 17. Reinstall the bolt that secures the detent spring and tighten the bolt to specification. Torque: 8~11 lb.ft (1.2~1.5 kgf.m/10~13 N.m) 18. Reconnect the solenoid harness to the solenoids and install the oil temperature sensor. Install 6 bolts to the harness and 1 bolt to the oil temperature sensor and torque to specification. Torque: 7~9 lb.ft (1.0~1.2 kgf.m/10~12 N.m) 19. Install a new gasket to the oil pan and reinstall the pan. Install 14 bolts to the pan and tighten the bolts to specification. Torque: 6~7 lb.ft (0.9~1.0 kgf.m/8~9 N.m) TSB #: 20-AT-003H Page 6 of 7 SUBJECT: ATM INPUT/OUTPUT SPEED SENSOR DTC P071200, P072100 & P072200 20. Attach the lower radiator hose, add ethylene glycol engine coolant to the radiator and check the level according to the appropriate shop manual, “Engine” Section. 21. Reconnect the battery. Input the radio stations recorded in Step 5. 22. Remove the transaxle fill plug. Use a funnel to add approximately 5~6 quarts of SP4-M ATF through the fill plug opening. Reinstall the fill plug. Attach the GDS and select Data Analysis, A/T menu and Oil Temperature Sensor. Start the engine and shift to Park. When the ATF is at the low end of 122°F~140°F (50~60°C), remove the level checking plug. The level is correct when oil flows out of the level checking plug in a thin steady stream. Collect and dispose of any excess fluid in accordance with local regulations. 23. Clear the DTC and test drive the vehicle for two key-on/key-off driving cycles, including 1-2-3-4-5-6-7-8 upshifts and 8-7-6-5-4-3-2-1 downshifts. If the DTC returns, perform the following repairs. DTC P071700 P072100 REPAIR PROCEDURE Replace the control wiring harness between the PCM and transmission. If the DTC does not return, return the vehicle to the customer.
