i have an 04 civic si. i gutted the cat (dumb) and check engine light came on. I bought an o2 sensor simulator from casper electronics. The light stayed on. And now i have installed 2 of those o2 sensor spacers/extenders that keeps the o2 sensor out of the exhaust pipe. The light stayed on. I bought a diagnostic scan tool to clear the code, but it comes right back on. Now my question is, do you think the o2 sensor is bad and needs replaced? What should i do? Open to any suggestions, and yes i searched......ALOT!

About the airbag, i unhooked the connector under the seat to try to make the seatbelt alarm quit beeping. Then the airbag light came on, and i hooked the connector back up. Reset the ECU, and light has been on ever since. Anyone know anything bout this? THX.

 

You need a new o2 sensor... I need one too but right now I don't have the 255$ Honda quoted me for the part!

 

buy a denso 02 from an autoparts store.

you need to reset the srs light. big pain in the ***. Just wear your seat belt and it won't beep. Hell it may even save your life someday cool guy.

 

yeah ive come to the conclusion that i need a new o2 sensor. i guess theres no way around the 200 and something dollar o2 sensor?
And how do i reset the srs light? Or is that something i can do?
I always wear my seat belt now.

 

Do you know how much the denso o2 sensor goes for about?

 

Quick Read DIY without pictures:
1. connect clip to yellow clip, turn key to position II
2. wait for the light to go off and remove the paper clip/wire.
3. As soon as the light turns back on, quickly connect the circuit again.
4. The light should turn back off. Remove the paperclip/wire again.
5. The light will wait a second or two before it tells you the follow word.
6. Final word is, 2 quick flashes and SRS light turns off completely.
6-A. two quick flashes and the light remains, you may be too slow or you have a short in your SRS somewhere.
7. turn off ignition and put back the clip.


Congratulations, you have successfully reset your SRS light.
