I heard that you can jump the diagnostic port, turn on the ignition and the check engine light will flash a couple of times giving you the code. I don't want to waste $40 for diagnostic reading..if someone here knows how to do it pls. give me the complete details. Thanks.

Actually, I believe that vehicles in all 50 states comply to the same standards with regard to the EFI diagnostics stuff. There may be some differences with emissions equipment, but that does not affect your ability to pull check engine error codes. I have found the following document to be very useful in terms of its explanation of pulling check engine codes on OBD1 (pre-1998) cars:

There are references to older, mid-80s Toyota vehicles in the document, but I believe that the principles of pulling the error code still apply to your car. I have an intermittent check engine light on my own car, which I will be the pulling code on very soon. Good luck, CL brother.

Any OBDII equipped vehicles cannot use this method to check for codes. But I do recall and the last time I checked on newer vehicles 1990 and up, the method only applied to CA vehicles. It should state it in the owners manual of your car. The first OBD II compliant vehicle in the world is the 1MZ-FE V6 equipped Camry and ES300 starting from 1994. Obviously the TE1 to E1 method will not apply since you need an actual code scanner to read the codes. The 3VZ-FE 92-93 ES and Camry V6 models are OBD I.

I must have the OBD II and OBD I mixed up. I thought that OBDII cars were newer and that you could pull those codes with a scan tool and OBDI cars required the method explained in the PDF file that I posted. Sorry if I mixed it up. In the case of my own vehicle, the scan tool does not work and you have to jump the T to E1 terminals. It's a '94 GS.

No you're right.
Certain OBD I and older vehicles, you can use the TE1 to E1 jumper
OBDII - Scanner only.

Well I'm done pulling the codes. First one is the Main O2S and the second one is KS Signal. Anyone knows about KS Signal and what part I should replace to fix it? Thanks.
