Do I absolutely have to have it or can I take it off? My 02 sensor has had my check engine light lit up for a while now but it's kind of expensive to fix that. Single mom, tight budget.

What are the code/s from the check engine light?

Will not pass the emmisions (smog test) inspection.

They sell universal model cats that are rather inexpensive, under $90.00. Shop around online and off. Check the cost at a couple of local muffler shops for installation.

Good hunting and post back. :)

The code came up as 02 sensor (had it done twice). I was told that my car has two of them. I will check on what you said. Thanks for your advice -- :wink: :wink:

Your welcome. :)

The front O2 tells the computer how much fuel to deliver. The rear O2 Checks on the function of the catylitic convertor.

There are 37 generic OBDII codes for O2s. :
Many things can be bad. The O2 itself, the wiring, the heater circuit, a blown fuse, and more. Best to narrow down the problem.

Good luck and let us know. :)
