: O2 sensors for a 2005 CTS-V

03-09-11, 09:00 AM

I just had the check engine light come on in my 05 V. When I got the codes scanned, they were P0155 and P0059 which equates to both the front O2 sensors. Can you let me know how much it would be to get 2 new sensors?

Also, slightly off topic, but does it seem odd that both sensors would go out at the same time?
