Check engine light on - think it is bad O2 sensor - is there any damage
that can result of running the van with out replacing this sensor? Only
drive less that 150 miles a month and vehicle seems to be running well
with no change in mileage, etc. Do not want to fork over the $200 to
$350
to replace it right not. Do any of the auto parts stores read the car
computer for a error code free?


Check Auto-Zone for a code reading. I believe that they advertise that
they do it, hoping to sell you the part.
Hi,
I built a OBD II to USB interface box from a simple kit. I use laptop to
read code. There are many freeware for this purpose. Not only reading a
code, the software can do all kind of things.
