hey guys, i have had the dreaded CEL for a while now, and it is for my right front 02 sens. well, the weird thing is it went away, and then came back. and now all of a sudden again, it came off. and luckily it hasnt came back. has this ever happened to any1? when your used to seeing the nast orange light everyday for a while, then not seeing one morning you can get very happy..lol. so what does this exactly mean?
well thanx in advance for any replies.

 

bumpppp !!!!

 

just because it left doesn exactly mean your problem is gone, your o2 is probably failing and so causing it to flicker.

check the o2 with a multimeter and see if you get the appropriate numbers (cant remmeber what numbers you should get dont have my haynes handy) butthat would be the best way to check and find out if its gone or failing.

Most likely you'll end up needing to change it.
