My speed control for my rc car has a red light, how do i fix it?

You need a mechanic with a high level scan tool to check the Diagnostic Trouble Codes and Live Data. It is probably ABS Sensor related, but should never leave you with no brakes..

Use the throttle trim control to try and adjust this unwanted throttle application out. Refer to the user manual on how to trim the remote functions

E3 - No speed sensor reading. Unit shuts down. This is the most difficult repair diagnose. The speed
sensor is connected to the frame of the treadmill near the drive pulley on the front roller. There is a
small magnet on the side of the pulley wheel. The sensor tip must be no more than 5mm from the
magnet. If for any reason the distance is greater than 5mm the treadmill will shutdown
Adjust or replace speed sensor.
Treadmill: Speed Sensor Replacement
1. Make sure your treadmill is unplugged before you begin.
2. Remove the motor cover located in the front of your treadmill, it is held on by a few screws.
3. Locate your speed sensor; it is the small T shaped part with a red and black wire coming from it.
4. Remove the 2 screws in the speed sensor and remove the old sensor.
5. Place the adjustment holder on the frame with the open holes facing the pulley wheel, the prongs facing
up and way from the pulley wheel. Insert the screws but don't tighten fully.
6. Now place the speed sensor over the prongs with the square part facing the pulley wheel and the red and
black wire to the far right.
7. Plug the treadmill back in and slide the speed sensor until it is 5mm from the magnet inside the pulley
wheel, you may have to do this several times until you can position it so it no longer shuts down. Use 2
nickels to figure out the spacing. The width of 2 nickels is 5mm.
8. Once you find the correct position tighten the screws all the way; being careful not to touch any of the other electronics
9. Place the motor cover back on and enjoy your machine.
Also:
Use an epoxy to glue it. It is a plastic that is difficult to adhere to.

If the brake light is on, check the fluid level immediately and add fluid if necessary.
After that, have the car's OBD-II computer scanned with a 'Brake Scan' tool for OBD-II. This will help to narrow down which wheel speed sensor is giving you trouble. It might be a broken wire, or a bad wheel speed sensor.

The wheel speed sensor sends information to the ABS side and the Traction Control side of the computer module for ABS and Traction Control.

The car will revert to standard braking and regular non braking transmission power distribution to the drive wheels when the ABS and Traction Control lights are both on.

Good luck on this repair.

turn down your idle screw and adjust your low speed screw to fix the problem that made you turn your idle up in the first place if you let the truck idle for 7 1000s and you mash on the gas it will do one of 3 things:
1) a nice crisp throttle response= perfect low speed setting do not adjust
2) engine bogs down = too rich, lean out low speed screw 1/8th turn until fixed
3) truck revs up but shuts off= too lean, richen low speed screw 1/8th turn until fixed

clutch bell and spur gear are not aligned and 100% paralal. When youre near fitting spur gear put a piece of paper through teeth. Should feel same through the complete turn. Also use thread lock on all bolts. Hope this helps.
