my obII reader is not pulling any codes ive checked my fuzes and they all check out good and im having a hard time trying to figure out what it is....
i went to the dealership and they were saying that is cause of bad o2 sensors and thats the reason the code reader cant pull the codes... does that sound righ>>>???? please any info would be great on how i can get this problem resolved...

 

go to advance or autozone and let them see what they pull up...from my knowledge, if its the o2 sensor, you get a SES and code citing which bank(s)

 

If the OBDII will not read codes alot of times its a fuse because somehow its linked with the lighter somehow. Check and see if your lighter works and if it does I don't know, hope that helps.

 

Light plug works fine.... ive checked the fuzes and they check out good... ima check em again.. but this is just annoying me... a shop was able to pull codes another way and its the same codes ive been getting for a while... can having a bad o2 sensor mess up anything if not fixed for a long time?
