hey, i found other threads with the question but noone gave an anser. Where is the IAT sencor located on a 91 accord?

On the hondas the IAT sensor is called a TA sensor, if you have a teardown manual or can get one I would recommend it. Haynes is my favorite
It should be located before the throttle body somewhere (vague), most likely in or around the air filter. It should be a two wire sensor and probably the only one in the air intake tubing. I'll repost if I can confirm this...
