I had been pondering purchasing an OBDII cable/solution for use on a computer for a while. It wasn't until I was faced with an impending state emissions test coupled with my dummy light being on that I finally leapt. I had previously taken my vehicle to my fairly trusty mechanic with the dummy light on. He found a code (P0141 for Toyota) that led to replacement of a post cat oxygen sensor. Somehow after that repair, the dummy light stayed on and the mechanic was a bit perplexed that the light was still on and stated he did not see a new code. Couple that with a few different statements that his OBD machine was just calibrated (should work) and he contacted a Toyota dealer, he was prepared to start testing ground on various points and hinted at the ECM needing replacement.

Well, I let this slip until the notice for emissions testing came. I figured if it worked out, the purchase of this OBD solution would pay for itself. The code I picked up was the P1155 code for one of the pre CAT air/fuel sensors. After looking the information up online and finally getting straight which sensor of the two the P1155 related to (its the one poking out of the heat shield), everything works. So, before factoring in the price of this cable, the part was 170 dollars or so. Minus the markup the mechanic would do on the part plus the at least hour labor, I saved the equivalent of the part and could have bought a few of these cables to break even.

Really this is a nice solution and the software that comes with the cable will work. There are a few choices on the CD, so try them all.
