Are These Codes Normal After Light Modding?

Dragon_Ball_Z · 03-28-2015, 10:47 PM

Hey guys, car is throwing this code every 10 miles. Are they normal? This is from DashCommand.

These are some of my mods:
Stillen Gen 3 intakes
Tein springs
Stillen sway bars
Berk HFC's
SPL rear camber arms
SPC front camber arms
RJM Clutch pedal
Fast intentions exhaust SS 18" resonators

The post cat O2 code is only one bank 1 -- the slow circuit/low voltage response may mean the sensor itself is damaged.

How can I test the sensor? Also there are O2 extenders on

What the hell, that's damn odd who did the installs ?

EDIT: nvm I just saw the build thread, that's sooooooo weird im running berks for around 7k now no issues

I'm not sure with dash command -- can you pull the actual DTC codes?

You could swap them back and forth to make sure it is indeed the sensor and not something due to a difference between the cats, but the voltage related codes point to a failing sensor -- they don't like to be removed...

I'd search for a generic replacement from Denso or Bosch and just swap it out.

The 2ndary O2 should be fairly inexpensive.

Gonna try this guys and does this affect my car any kind of way?

Just threw this

Hmm. The bank 2 sensor is showing codes too -- I still think the low voltage is due to the bank 1 sensor being damaged, but it looks like either way you'll need to deal with the lean code CEL's for both banks either via tune or trying to add extra extenders on each bung.

There are O2 extenders on there

I see you had the Cats replaced and kept the stock headers. When my shop did this, they used an impact tool with extensions to take the cats off. The impact tool toasted my O2 sensors and I wound up having to replace both of them. The denso replacements are $100/unit.

If your shop used an impact tool to get the stock cats off, without taking the O2 sensors out, this could be the issue. In my case, they also rounded out a bolt, so I never got my RTPs on. I wound up going LTH and replaced the O2 sensors when I had them installed.

GL!

Edit: Just looked at the build thread..... looks like they didn't use impact so........ IDK

Dragon_Ball_Z · 03-30-2015, 11:24 AM

Thanks looks like I'll be replacing O2 sensors. I'm not feeling a difference in driving. Would this affect my car or just trigger light?

jabo5779 · 03-30-2015, 11:29 AM

It didn't affect anything for me.... I drove for a week with these type of codes. Any weird affect you feel might be from the car needing a tune though..

Dragon_Ball_Z · 03-30-2015, 11:30 AM

I don't want a tune :/ I'm waiting to go FI Lol. I'm thinking the car can wait a year without a tune or 15k for me to get a TT kit lol

That's some funny **** right there. $5k? You're going to need to triple that number to do a twin turbo kit right. For a single turbo, just double it.
