The sensors are located on the front wheel hubs , and usually these don't go bad unless exposed to physical damage. However the more common culprit is damaged wiring between the sensor and the main wiring harness. Look for a connector on the inside of the wheel hub, follow wire into the engine compartment. Look especially near the A/C compressor, as a wiring loom is located very close and can be dislodged and rub the wire. Any kinked or nicked wire must be replaced. The computer keeps seeing false signals and reduces power in an attempt to stop wheel spin, which of course in your case is truly annoying.

2003 mustang when traction control light comes on the car lose power almost like shutting down, when it goes off it pick up speed.

The traction control system DOES cut your engine power when the tires spin. That is by design. The system cuts engine power to stop the wheels spinning and restores power once the wheels regain traction. It feels odd when the tires spin and power cuts out. It's good practice to lift off the accelerator when the system kicks in. Otherwise, if you are on gravel or slick streets the tires may spin, stop when traction control kicks in, and then spin again when power is restored. It is not an "elegant" solution but it does work for the most part.

May or may not have anything to do with the engine light, the traction control system is shut down due to the check engine light , whenever the computer sees the engine is not operating within specs it will turn on the engine light and also the trac light, the first thing to do is have the computer scanned to see what the codes are that are stored in the computer.there are many auto part stores that will scan it for free and give you a print out of the codes, if you can get the codes i can help you further but the codes are the first far as the tires i dont think that has anything to do with it,it sounds like a bad sensor or maybe something got left off during the fluid repair , the codes will help in this. good day

P0300 code with the traction contol light popping on

Yes it does,the traction control is controlled threw the p c m,and if the tire size has changed there will be a vehicle speed sensor sendig the wrong information.Check with the dealer on what needs to be changed to accomodate the tire change,I think it will be a reprogram to the p c m.

ABS and traction control really are only for panic stops and if your tires slip on wet surface's and yes each tire has a sensor on it. However if the brake light comes on this has nothing to do with the ABS or traction control lights. It's not a parking brake light. This light tells you, you have a serious brake problem.

Traction Light

If the orange light is the light that keeps coming on, then you may have tire issues. Mounting different tires from the Goodyear Eagle F-1 or the Goodyear Supercars can cause the car to think that it is loosing traction (especially if the tires are of different sizes than the original tires).
