How to find out why the check engine lights on? its obd1
I have a 93 gs300 and its obviously obd1 and I was wondering if any of you had the book on how to check it. I think one of my o2 sensors are bad and im just trying to find out which one it is. I know its something like connecting the pins and counting the light reps to find out the code but i would like to have the manual if you can scan it or link me to it that would be great.

Jump TE-1 and E-1 as shown in the diagram here and count the flash sequence of the check engine light with the ignition turned on. Here's the link:
