my 330000 mile tacoma has had that on since the first of the year. investigation with my scantool says its a failed transmission temp sensor #2. it is a known issue that the a340 transmission in the truck has a corrosion problem with two pins on the harness connector for the tranny to the ecu. so rather than open it up to replace a maybe bad sensor, i just clear the code and let it pop back on once the truck is up to operating temp. winters keep it cool enough most times not to throw the code at all

This is the way. You open it up and you’re introducing more chaos. Guess you’ll just need to be a little vigilant when the light comes on to make sure you’re not running into any other issues. That being said, you can usually feel if there’s a problem. Or smell, but if you smell the problem it’s usually too late.
