My car has been sitting in my garage for about 1 month now without being started, I put fuel stabalizer in it before I garaged it.
Last week I took the catback off the car (I still have a test pipe w/ 02 sensor going into the header).
I just started the car today to move it to another spot in the garage and I threw a CEL. I haven't checked it yet, mainly becasuse I don't even plan on driving it for another month or so, but I'm wondering if not having the catback on would throw the CEL? And when I put the new exhaust in everything should be fine right?

If you didnt have the cat on it will more than likely throw a code. No need in putting stabilizer in there if its only a month or two..

Yeah, I didn't put much in - just figured, better safe than sorry. As for the cat, I only have a test pipe, do you think that would make a difference?
chances are the O2 sensor is too close to the exit of the test pipe, causing the mixture at the sensor to get fresh air sucked into the test pipe because there is no cat back, and causing the CEL. this is why when I had to get tuned with no cat, I needed to relocate my O2 sensor bung much farther away from the end of the downpipe, it will throw off the readings. check the CEL just to be safe, its probably secondary O2.

No, there is a primary and secondary O2 sensor on all OBD2 cars. The secondary O2 sensor should be after the catalytic converter. Your car with throw a code without it.

Yeah I just checked it, 02 sensor is about 2.5 inches away from fresh air. I guess I'll find out when I throw the new catback on there and fire her up again.

Ok now I'm confused. I don't remember EVER seeing an O2 sensor AFTER my test pipe / cat. Maybe I'm just smoking giant crack rocks? Here.. I went and took pictures.


So your telling me there should be another O2 sensor built into the catback exhaust?
PS. That is a DIY test pipe, and I'm not sure what header it is either, I think JDM ITR but I'm not positive, came with the car.

There are 2 sensors...One before the cat convertor...One after....
The ecu does this magical thing called subtraction and subtracts 02 reading from the first from the second. If the difference isn't within a certain yield then the ecu thinks the cat is broken (or in your case not there).
But the car should be running in closed loop until it gets warmed up. So it shouldn't be reading 02 readings until its in open loop. Is your sensor physcally gone? or did it not throw the code until the car warmed up?

Ok, I guess I am just smoking crack rocks, I climbed under there again and found the primary O2 sensor at the collector end of the header.

No, the CEL threw immediatly when I turned the car on. should I try to do the paperclip trick to see what CEL I'm getting? Or just wait until I have an exhaust?
Also, can anyone identify what header that is? I think it's a JDM ITR w/ 2.5 collector, not sure though.

ditto
yes that looks like the JDM header.

Okay.. so I did the paperclip trick..
Throwing the following codes
CEL: 22
ABS: 53
SRS: 11 - I have JDM non SRS wheel so this is to be expected.

CEL 22:

Anyone know what this is / how to fix heR?
RTW DC2R - will buying your Ported Vtec solinoid fix this problem? Haha...

Looks like it's time for one of Ryan's ported VTEC solenoids...
