Where is the vss on the 2009 corolla? i know its on the transaxle but Im having a hard time locating it..

you have to raise vechicle support vechicle on jack stands. remove right front wheel. VSS sensor located upper right end of transaxle near the right inner CV joint.now your vechicle transaxle 4T65 E has a VSS and a ISS SENSOR which located inside transmission thats dealership fix. you have to remove case cover to remove the input shaft speed sensor.

Hi there:
The VSS (Vehicle Speed Sensor) is mounted on transaxle and contains a three pin electrical connector. Remove necessary components for access to VSS. Disconnect electrical connector at VSS...




Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

There are 2 different listings for a VSS for that model Corolla - one for the 1.6 3 speed automatic, and another for 1.6 manual and all 1.8 applications. It appears to be located on the top rear side of the transaxle case.
When the light comes on, does the speedometer act strangely?

Most definitely it will.

probably it will be the vss ( vehicle speed sensor ) problem its located on the flywheel
thats why the computer cannot detect speed in right measures and thats why it cannot control the stability control system because it can`t read the car`s (wheels) speed in right manners so it halt the both systems ( the fuel injection calculating pattern and rotation of wheels )
its common thing easy to fix and reset the computer allowing the check light to be off

ALL YOU HAVE TO DO IS SAFELY RAISE SUPPORT VECHICLE ON LEVEL SOLID GROUND.THE VECHICLE SPEED SENSOR LOCATED ON THE TRANSAXLE ON THE OUT PUT SHAFT HOUSING.YOU NEED TO DISCONNECT THE ELECTRICAL CONNECTOR FROM THE VECHICLE SPEED SENSOR.THEN REMOVE THE MOUNTING BOLT WITH DRAW VSS SENSOR FROM TRANSAXLE.REPLACE THE VSS OR VECHICLE SPEED SENSOR AND O - RING.YOU ARE DONE.INSTALL THE NEW VSS SENSOR AND NEW O - RING IN TRANSAXLE. THATS ALL.

On the transmission.

Removal & Installation 3.0L (Except SHO) To Remove:

1. Disconnect the negative battery cable.
2. Raise and support the vehicle.
3. Remove the catalytic converter Y-pipe.
4. Unplug the vehicle speed sensor VSS electrical connector.
5. Remove the VSS protective heat shield.
6. Remove the retaining bolt from the VSS.
7. Lift the VSS out of the transaxle.
8. Remove the driven gear retainer and the drive gear.

To Install:

1. Inspect the O-ring on the sensor and replace if necessary.
2. Install the driven gear and the retainer.
3. Place the VSS into the transaxle.
4. Tighten the retaining bolt to 36-53 in lbs. (4-6 Nm).
5. Install the VSS protective heat shield.
6. Attach the VSS electrical connector.
7. Install the catalytic converter Y-pipe.
8. Lower the vehicle.
9. Connect the negative battery cable.

This is what it looks like:

hi..the transaxle converter clutch . tcc. uses a solenoid -operated valve located in the automatic transaxle to mechanically couple the engine flywheel to the output shaft of the transmission through the torque converter.that reduces the slippage loss in the converter.reducing emissions.but check the vss first.which is called the vehicle speed sensor.they both work together .if the vss is not working right it wont call on the tcc.
check this out..
thank u..
rate me..

The vehicle speed sensor (VSS) is located in the differential area of the transaxle. Also, to replace it should be fairly simple. I wish I could give a better answer exactly where it is at, but I have you the answer straight out of the Haynes manual.  

To replace the VSS, disconnect the electrical connector from the VSS. Then remove the retaining bolt and lift the VSS from the Transaxle or simply unscrew the VSS. Installation is the reverse of removal.
