pulled 2 codes today after my check engine light came on. a 03 03 and a 03 04 front left heated o2 and knock sensor. is this something u can do yourself and if so how much do the sensors cost? im trying to look in the stickies but my comp. keeps freezin(F-ing computers)man im freaken out i just got new tires, alternator, belts, brakes , and 2 cv boots so im kinda broke.and will it further damage my car if i drive with the light on for a couple of weeks?

 

Replace the O2 sensor first, there around $90. Then reset your CEL and check it again after driving for a couple weeks. Its likely only your O2 sensor, but it will sometimes trip the knock sensor code even if nothing is wrong with it. The knock sensor itself will not give you a CEL.

 

thank you. can i get the o2 at auto zone or does it have to come from dealer?
and is it ok to drive for a couple of weeks until i get some cash?
