    I have an 09 access cab tacoma. Last week suddenly my brake lights would always stay on, even if the key was removed from the ignition and lights were off. Two days after that my check engine lights turns on and a little truck with fishtails on it lit up to. I took it to toyota for them to look at it. and something is wrong with the break sensor. How and where do i find it on my truck and has anyone else dealt with this same problem?

    You should look under the dash where the brake pedal is, there is a plug/sensor down there that turns the lights on. I've kicked it a few times and had the same problem, takes about 30 seconds to fix if thats your problem.

    Everything is covered if it is less than 36 months and less than 36,000 miles.

    Are you over the mileage?

    Brake switch at the top of the pedal... Thats the first place to check anyways, could just be stuck on. If not, Dart on over to the relay!

    The little 'fishtail' indicator means a failure in your traction control (VSC / TRAC) system. There are no 'brake sensors' involved in the basic stoplight activation function. The Skid Control ECU is capable of activating the brake lights (given an electrical fault) regardless of the position of the brake pedal switch.

    IMHO the more likely explanation is that you have a fault with the VSC / TRAC equipment, not the brake light switch on the pedal. My guess is that the 'brake sensor' they referred to was one of the ABS speed sensors (which is involved with the VSC / TRAC functions).

    Do you mean it was unplugged?

    I have similar issue but not identical. Mine stays on while the engine and headlight is on. So you unplugged and plugged it back in? I hope you didnt leave it unplugged. That would mean trouble.
