How long ago did you replace the cat? Your engine is running very rich, which can kill a cat quickly.

Have you done an ignition system tune up -- plugs, wires, cap, rotor, ignition timing?

I just found out right now that my car is running on a p05 ecu..which is for cx model...since mine is a
Lx model. I believe lx is suppose to be p06...maybe that might be the problem..

 

[reg_lus]

Cud even I rev it, it redline at 6000 rpm and I believe its suppose to be 6500 rpm..

 

[RonJ]

What engine is in your car? Is it a D15b7 or D15b8?

 

[reg_lus]

d15b7

 

[RonJ]

Yes, you need a P06. The O2 sensors for the b7 and b8 are also different.

 

[reg_lus]

thanks! i just bought a p06 for like $60..hope this time it'll pass

 

[emerican]

good luck man i hope it fixes the problem and you can pass the test.

 

[reg_lus]

Arlight! I pass! Damn feels great! lol It was because of ECU..I had a p05 in the first place but I replaced it with the p06. Problem solved!

 

[emerican]

glad to hear it man

I also failed my smog when I got my EG8 with a D15B7. I was always curious as to what made it fail. Can you guys give me info on how to check my ECU? Where it is, how to determine what kind it is...that's basically it..haha thank you!!

Pull out ur ecu...there should be a code on the side. it should say P06...If you have anything else different
from that P06, then you got a different ecu.

But failing smog can be a something else unless you got a wrong ecu

here's a little help i put up..this is the CX ECU p05

Thanka you two! Only problem is idk where it is exactly. I've read that it is attached to the firewall
on the inside on the passenger's side... I'll check after I eat some breakfast

It's behind the passenger side kick panel:

Thank you sir! I check, turns out its on the floor..... I bought my car when I was a lot younger, it was in such bad shape. No flywheel cover on tyranny, missing motor mount, ECU not in place, SRS light always on because "the cables weren't attached under the seat"... I'm trying to fix it little by little. Good news is that it is the appropriate ECU for my motor!

Yeah the ECU is located on passenger side fire wall...Just pull out the mat and it should be on your right side.

If it didn't pass smog for any reason, you should try what I did:

Change Air Filter
Change Oil
Change Spark Plug (NGK Iridium)
Change Catalytic Converter
Change o2 Sensor

I have til October to pass it. The last two on that list are the ones I need to change for sure. I just need to find a CA legal cat:/
