Just recently did a powersteering/ac delete and now my buddies car is throwing a cel for code 41 primary oxygen sensor heater. I checked all fuses/relays and the plug itself and everything seems up to par. What could be the cause of this? The delete wouldn't do this would it?

 

Have you tried replacing the o2?
