Speed sensor location on a 2006 Toyota Corolla?

Question edited for clarity.
Question moved from MISC to make model category.

You mean the lights in it? Fuse 18.

Or the actual speed information? No fuse, the data comes from a speed sensor and it processed by the ECM and BCM. Videos in the link.

The speed meter cable arises from rear middle side of the transmission and is attached to the rear of combination meter assembly. It is a two part system. One is the inner speed meter wire and the outer cable or sleeve, in which the inner speed meter wire rotates to show the vehicle speed. The speed meter cable is in some Toyota models is made up or two cables, a smaller cable near the transmission side and larger one towards the meter, which are joined together to form a single piece First look up the inner wire of smaller piece and then pull out the other larger inner wire, without removing the whole cable. If it is found broken, replace the whole assembly.
To replace the speed meter cable assembly, unscrew the cable at the transmission side. Sit on a driver's seat, open the Philips screws from under side of the combination meter. Pull out the whole cover by tilting it to release from the steering wheel. Unscrew the 4 Philips screws, pull out the meter assembly a bit, bend your claw to approach behind the meter assembly, push the speed meter plastic lock force fully towards the cable and pull out the cable.
Ask your companion to slowly pull out the cable from the engine compartment side and you also push the cable towards the same direction simultaneously to take it out.
Install the new cable in the reversed order of dis assembly.
Hope that works. Thank you.

Output speed sensor usually located in transmission usually close to where axles go into transmission. The sensor can be identified by having 8 mm headed bolt that hold the sensor in. These speed sensors just don't quit one day. A wire is usually the culprit or debris on magnet of sensor or physically broken sensor. If speedometer intermittently starts working then its always a wire with bad connection.

speedometer controls the cruise control.the speed sensor is located on back of your transmission. using scanner select live data and drive. scanner will read the speed. if not replace the sensor.reset any code from computer.
good luck

Check for loose connection of the speedometer wire at both the transmission or the speedometer assembly. If OK, replace the vehicle speed sensor.

Based on your actions, it sounds like a wiring problem.
Could be a weak connection at the cluster, or the speed sensor.

The vehicle speed sensor is located below the air cleaner assembly, it is held in with one bolt (I believe 10mm):

1. Remove the bolt and vehicle speed sensor assembly.
2. Remove the clip and speedometer driven gear from vehicle speed sensor.
3. Remove the O-ring from vehicle speed sensor
4. Coat a new O-ring with ATF and install it to the vehicle speed sensor.
5. Install the speedometer driven gear to the vehicle speed sensor and clip.
6. Install the vehicle speed sensor assembly and torque the bolts. Torque: 16 Nm (160 kgf-cm, 12 ft. lbs.)

if is a fuse im nearly sure all the clocks would stop working.if this is not the case.replace the speed sensor tht lives on top of the gearbox.best of luck
