How To Determine Check Engine Lights Codes?


Recommended Posts

Ever since I put the new motor in my 95, the check engine light has been on. I was wondering how to check to see what was causing it. Its not an OBD2, so I can't plug in my buddy's scan tool. I know on all my hondas the ECU had a light or I would jump 2 wires and the check engine light would flash the number code. How do I check on my Lex? This is my first time owning a Lexus, so I don't know the ins and outs of it yet.
