Saponetta

Hello,

Thanks for letting me join. Have a 2000 acura rl. 140k do all the maintenance and repairs myself. I have fault code/ check engine light with code c3401 pop up. Yes with a C. Cannot figure out what the heck this code means. It only popped up about 2 weeks ago. Car has no running symptoms. Has periodic srs and abs lights. But they only go on briefly and disappear not even on for a whole drive cycle. I need to re register the car before months end, so i need to get on this. Any advice would be greatly appreciated. Jist want to say before hand, I listen to advice, do the tests and diagnostics requested. I'll listen, please help, your advice wont fall on deaf ears. Thanks in advance for your time and efforts. It's been a great car. Interior still looks new. I'd hate to send it down the road cause I cant redo my plates.

Found this but don't know if it applies in your situation but gives you a starting point for trouble-shooting.

I fortunately, those are all just like spam crap. Check a few of them or read one over. Its nonsense. One will say its egr code, another an o2 another a misfire, just random crap.

A little more history, I just replaced and fixed b2s2 o2 sensor for a different code weeks before.
