Transmission Temperature Sensor/Switch: Testing and Inspection
ATF Temperature Sensor Test/Replacement1. Make sure you have the anti-theft codes for the audio system and the navigation system (if equipped), then write down the audio presets.
2. Remove the splash shield.
3. Remove the drain plug (A), and drain the automatic transmission fluid (ATF). Then reinstall the drain plug with a new sealing washer (B).
4. Disconnect the battery negative cable, then disconnect the battery positive cable.
5. Remove the battery hold-down bracket, then remove the battery cover, the battery, and the battery tray.
6. Remove the intake air duct and the air cleaner assembly.
7. Loosen the two bolts securing the battery base from under the vehicle, and remove the two bolts securing the battery base in the engine compartment, then remove the battery base.
8. Remove the ground cable (A), the transmission upper mount bracket (B), and the bracket plate (C).
9. Place the transmission jack under the transmission, and remove the transmission lower mount nuts.
10. Lift the transmission up to create clearance between the transmission and the front subframe with the jack.
11. Remove the ATF dipstick, and remove the bolts securing the ATF cooler inlet line brackets (A) and the ATF dipstick guide pipe (B) from the transmission hanger (C).
12. Remove the harness clamp (D), then remove the ATF dipstick guide pipe.
13. Disconnect the shift solenoid harness connector.
14. Remove the shift solenoid valve cover (A), the dowel pins (B), and the gasket (C).
15. Remove the shift solenoid harness connector.
16. Measure the ATF temperature sensor resistance between shift solenoid harness connector terminals No. 6 and No. 7.
Standard: 50 ohms - 25 kohms
17. If the resistance is out of standard, replace the ATF temperature sensor and the solenoid harness; go to step 18. The ATF temperature sensor is not available separately from the solenoid harness. If the measurement is within the standard, install the removed parts; go to step 21.
18. Disconnect the connectors from the shift solenoid valves.
19. Connect the shift solenoid valve D connector with the ATF temperature sensor (F) on the shift solenoid harness.
20. Connect the solenoid valve A connector (BLU wire), solenoid valve B connector (ORN wire), solenoid valve C connector (GRN wire), and solenoid valve E connector (RED wire).
21. Install a new O-ring (G) on the shift solenoid harness connector (H), and install the connector in the transmission housing.
22. Install a new gasket, the dowel pins, and the shift solenoid valve cover.
23. Install a new O-ring on the ATF dipstick guide pipe, and install the ATF dipstick guide pipe, then install the harness clamp on the ATF dipstick guide pipe.
24. Secure the ATF cooler line brackets on the transmission hanger with the bolts.
25. Check the connector for rust, dirt, or oil, and clean if necessary, then connect the connector securely.
26. Install the transmission lower mount nuts.
27. Install the transmission upper mount bracket, bracket plate, and the ground cable, then remove the transmission jack.
28. Refill the transmission with ATF.
29. Install the battery base, then install the air gleaner assembly and the intake air duct.
30. Install the battery tray, the battery, and the battery cover, then secure the battery with its hold-down bracket.
31. Clean the battery posts and cable terminals, then assemble them.
32. Install the splash shield.
33. Enter the anti-theft codes for the audio system and the navigation system (if equipped), then enter the audio presets, and set the clock.
