Engine Diagnostic Tool, How to check a check engine light Options

[mschulman]

Hello All,

Does any one know of a good diagnostic tool to tell if anything is wrong with a Celica engine? My wife’s Acura’s engine check light came on and I found this tool:

http://216.65.58.60/Merchant2/merchant.mvc...egory_Code=CODE

It says it will work on any car 96 and newer (I have a 99).

The port in the picture doesn’t seem to match the diagnostic port on my engine and I am not going to buy it unless we can use it on both cars. Does any one know if it will work on the Celica? I could not find the OBT II certified stamp on any of my Celica’s tags. Does any one know of a tool that can diagnose a Celica?

Thanks!!!

Thanks! I took it to autozone and they plugged their thing in and it said “EGR valve has insufficient flow.” The guy there had no idea what it meant. I looked it up and its the valve that’s lets exhaust back into the intake manifold as needed. I took the valve off and it was stuck shut with carbon, I opened it and it opens and closes now with the vacuum. The engine check light is still on. Does it go off automatically or does it need to be reset after the repair is made?
