Something’s wrong

    I’ve been able to reset the codes on my ’03 Taurus by disconnecting the battery for a couple of minutes. A guy at the local parts shop told me that that works for many OBDII cars. He wasn’t, by the way, employed by the shop. The guy behind the parts counter said he wasn’t allowed to tell me how to clear the codes.

    This much I knew. I also know that if there’s some actual problem, by the definition specified — emissions that exceed spec by a factor of 1.5 — the light will come back on some time during the second trip.

    A friend recommended a scan tool from; the price is right, but I am put off by this customer review, in which two units failed to read on a car awfully similar to mine. (And I’ve had P0430 before. It is not pretty.)

    My codes on the ’03 Tortoise were related to a vacuum leak. The guys at the shop wanted to sell me oxygen sensors and other expensive goodies. Even after I fixed the leak, and the light stayed on, they insisted I needed to replace all of the oxygen sensors on the thing. The guy that told me about pulling the battery cable saved me over a hundred dollars. :)
