does anyone know how to avoid throwing the CEL when fitting a test pipe up to a 99 teg? thanks for your help guys...

 

According to the guys on this board, you can do the following:

Unplug the 2nd O2 sensor. Unscrew it from the cat. Put it in your pocket. Then go up into the passenger compartment, and locate the carpeted space behind the radio. Pull it up to expose the other side of the wire connector and pull the wires up so that you can plug the sensor back in. Do so. Then get some aluminum foil, and wrap the sensor in it. Put the wrapped sensor in a plastic baggy, seal it up, and secure the package behind the radio somewhere. Reset your ecu.

I have yet to try this, but I will be doing it tomorrow, so I'll post up here if it works for me or not.

 

Yup, this is what I did. One thing though, you might not wanna wrap it in a plastic bag because the o2 sensor gets really hot. I'd just leave it wrapped up nicely in foil and zip tie it somewhere behind the radio. The plastic bag would probably melt.

 

I don't think it gets hot enough to melt a plastic bag, but i wouldn't chance it.. I have mine tucked away between my carpet and plastic kick panel thingie.. This absolutely works, and works just fine.. Basically on the obd2 cars, this o2 reads that the cat is doing it's job, so the cleaner the air the better, and obviuosly it's clean in the cabin.. good luck!

 

Depends on the thickness of the plastic bag I guess. Not worth the risk. The aluminum foil is good enough.

 

Get a high flow cat it work almost as well as a test pipe and no cel!

 

My friend Mike and I are going to make test pipes for our cars. Mine is a 94 and his is a 96, both integra with b18b's. I won't have to do that, but he will, Right?

 

Man I couldnt find the hole under the radio carpet and didnt really feel like totally ripping it up so I just welding a bung onto the test pipe and that was that. Spent more time tryign to find that damn hole than it did to actually put it back into the test pipe. Oh yeah welded my cat shield to the test pipe too for those damn pesky cops w/ mirrors.

why couldy i just leave it in the test pipe...does it not like reading the nasty air going thru the pipe? is this why i will get a CEL?? sorry, i just dont understand that much...oh and the reason why i dont want high flow is the price...i can get test pipes for like 45 bucks...

 

This is going to trip the CEL (check engine light).. As stated above, the second o2 reads and makes sure the contents AFTER the cat are clean, and in the case of a test pipe, they will not be..

If u haven't tripped the CEL it will in the next couple times u drive your car..

Correct, anyone with OBD1 (pre-96) will not have to worry about any of this.. The o2 sensor is before the cat in your instance, 1994 model..

 

Yeah, your cel will be tripped. You should've covered the o2 with aluminum foil and zip tied it under your car. Good idea about welding the cat shield though. I was gonna do the same.
