CEL??? on and off?
I recently did an aem CAI and DC header. Everything was running beautifully until about a month after the install the car threw a bank 1 sensor 1 o2 sensor low voltage code. The funny thing is it comes on for about 30km of driving distance and then shuts off on its own and I can drive around for another week or two weeks with no CEL and then it pops up again and then goes away again. Also, my car only has 80,000km's on it. A little premature for an OEM o2 sensor, no?
Any thoughts or input would be helpful.

The O2 sensor may have gotten damaged while swapping it over to the new header.

It can't be the header that is causing this, can it? Anyone with a DC header come across this issue?

Anyway I bought a rebuilt NAPA MAF for $90 and put it in my Yaris since the Yaris one was in his ECHO and he's hard to get a hold of. We sold the ECHO and I forgot to swap sensors beforehand! Its been a few years now and that $90 part still works!

I'm just confused because with my experience with o2 sensors is that when they go they go. They don't work some days and not on some other days lol. That's really what is puzzling me.

I had a similar issue a few months back. The "O2 heater circuit" code would come up randomly sometimes. Swapped it for another one and the code went away never to be seen again. :P

Check your wiring at and around the O2 sensors where you were working. Make sure you didn't pinch a wire, or scrape some insulation off of a wire that may be intermittently touching bare metal. Shorted wires will cause crazy stuff.
2nd, put a scanner on it to get the code it is throwing. That way you'll at least have a starting point. A lot of today's scanner have troubleshooting info in them that will give you tips as to where to start looking for the problem. If you don't have access to a better scanner with troubleshooter info, go to Autozone, they can at least put a generic OBD2 scanner on it to pull a P code. |

I`m probably just going to swap it out and hopefully that will be the end of it. I`ll update you guys when I have done so. Thanks for all the input guys!
