Transaxle Fluid Temperature (TFT) Sensor Removal/Installation

WARNING: This page is about a different variant/trim than selected.

WARNING:

A hot transaxle and ATF can cause severe burns. Turn off the engine and wait until they are cool.
Using compressed air can cause dirt and other particles to fly out, causing injury to the eyes. Wear protective eyeglasses whenever using compressed air.

CAUTION:

Water or foreign objects entering the connector can cause a poor connection or corrosion. Be sure not to drop water or foreign objects on the connector when disconnecting it.

Remove the primary control valve body.
1. Disconnect the negative battery cable.
2. Remove the air cleaner component. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION .)
3. Remove the aerodynamic undercover NO. 2. (See AERODYNAMIC UNDER COVER NO. 2 REMOVAL/INSTALLATION .)
4. Clean the transaxle exterior throughout with a steam cleaner or cleaning solvents.
5. Drain the ATF into a separate suitable container. (See AUTOMATIC TRANSAXLE FLUID (ATF) REPLACEMENT .)
6. Remove the front crossmember. (See FRONT CROSSMEMBER REMOVAL/INSTALLATION [MZR 2.5] .)
7. Disconnect the coupler component connector.
8. Remove the oil pan.
9. Remove the primary control valve body. (See CONTROL VALVE BODY REMOVAL/INSTALLATION .)
