My check engine light started coming on about a week ago, so I took it to a shop that specializes in Toyota/Lexus, and they told me that my speed sensor and starter sencor are causing it to come on.

Now is there anything I can do myself so I don't have to pay them to diagnose it for me, because the truck starts fine, and drives fine.

I need to save cash since I'm only $400 away from completing my stereo ($1000 in so far)
