Check engine light code: P0724 - Toyota Yaris Forums

P0724: Torque Converter/Brake Switch B Circuit High

Anyone ever ran into this before? My girlfriend's 2007 Yaris Hatchback just threw this code and I have never heard of it before. Any idea if this is something I can repair or does it need to go into the dealer? Any information is appreciated, thank you.

Cheers

Do the brake lights work, or are they stuck on or off?

I've had this same code a few times recently and it seems to go off on it's own over time, althought I have reset it on a couple of occasions. Car is manual and appears to have no issues with the brake lights either not coming on or staying on. Timing of the error code appearing seems to be related to when I swapped the O.E.M. brake light bulbs with L.E.D. ones. Does anyone feel this could be the potenial problem? Thanks in adance for your thoughts.....
