I Just ran the OBD2 scanner, My CEL is on for 2 days now. I pulled the code P1167 = heated 02 sensor. What could be wrong here?

My car info: Headers (w/o CEL fix), Test Pipes (w/ CEL fix), Full Exhaust.

I have had all the mods for about 5 months, then recently my CEL went on (2days ago).....

But I erased it. If it comes back on. Any suggestions?

 

don't hold me to it, but doesn't that mean there could be a leak?

 

If it comes back on, check ur 02 sensors or if there is leak. Have tune your car? If not i would recommand tune your car since you running with headers.
