2001 Toyota Seinna Van & check engine light

Posted by hillclimber on October 17, 2009, 4:47 pm

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?

Hi,
If it is O2 sensor, you can replace it. Just need special socket.
It does not cost so much. Sure )2 sensor is bad? You read OBD II code?
There is posibility it can damage cat. converter.

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.

Autozone.

there's at least TWO O2 sensors,one before and one after the converter.
V-6s and V-8s may have double the number.(Bank 1 and Bank 2)

The front O2S is used to adjust fuel mixture for best combustion,and the
after-O2S checks the converter for proper operation.If you run the
converter too rich,it gets extremely hot,the insides melt or fracture,and
then the exhaust is restricted,and the motor suffers.

and you probably will not pass any emissions test your state may require.
