dannydavi · 04-03-2007, 08:01 PM

Hello guys, i am getting error codes 14 and 21 when i do the diagnosis, i read what they meant, but having a hard time understanding the problem to fix.
Mr nickeleye had replied to my last posting saying "intake" but unfortunately i am still not competant enough about engine performance as i would like to be to understand what to fix, any info helps guys, thanks.

hey you guys, doing some work finally on my car in the next couple days, and any info will help. Thanks.

21 is your Oxygen sensor. Replace it.

14 is your igniter. You can check it with a multimeter, but it probably is bad if its throwing a code.

Good luck.

thanks man, i have a multimeter so i will check that tomorrow. And the o2 sensor huh. i guess i'll have to pick one of them up.

hey guys im speaking with a live rep on a parts site and she wants to know if i want front of cat O2 sensor or what? i really dont know. im assuming front of cat.. any info?

dannydavi · 04-13-2007, 05:47 AM

i found a diagram in the TSRM which labels the O2 sensor in front of the (TWC) three way catalyst. Does that mean front of cat.. hmm.

correct you are, the diagnosis gave a few options to check, when i pulled my O2 sensor off the flange thing was broken, metal thing around inner tip missing i think and for regular maintenance arent we supposed to replace them every 30k was it? im not sure, but now it's new and wont have to worry about it for a while. but your right it could be something else, im going to run the diagnosis again after a bit of driving and see what i get.. plus im always trying to maintain my car so i hope i catch any other things.

dannydavi · 04-20-2007, 05:08 AM
