Engine Code P2197

Okay so im new this so I need a little help. I have a 2005 V6 and I have a BBK Cai thats not "supposed" to require a tune and a GT takeoff muffler. But after installing those I keep getting the Engine light code P2197 what does this mean and what can I do to fix it? The car runs perfectly fine still though. Thanks guys!

My understanding is that this code relates to excess air entering the combustion chamber (O2 sensors). Is the CAI connected properly to the TB? No leaks? See the link. Different year but same issue.

You need to replace the front drivers side 02 sensor and that will take care of the issue.

Okay is the bad O2 sensor a known issue?

My 2011 V6 threw the same darn code 4 months after my buddy installed my BBK headers and off road x pipe. At first I thought it was a glitch because the car was running fine and I would just clear the code using my performance tuner. Every few days after the code was cleared , the check engine light would come on. I would check using my performance tuner to read the computer and it was the same 02 sensor code that you are also getting and I first got.

I began calling American Muscle and doing research along with asking my mechanic friends. The problem was either a bad 02 sensor or had an exhaust leak. I took my car into an exhaust shop and after examining the car, no exhaust leak what so ever. I excepted the fact the solution was too spend 114 dollars on a new 02 sensor, so I called AM and ordered one. It came several days later, I installed the new 02 sensor and poof, no more check engine light. Problem solved. My factory 02 sensor just went bad around 24,000 plus miles. Because of the bbk headers and x pipe I already knew this factory 02 sensor would not be covered under a warranty item because of the modification.

I just think your factory 02 sensor took a dump, not so much a known problem and unfortunately stuff breaks. Hope this helps you!

Glad to hear. Keep me posted on what you do? I'll follow this thread. Also, I found AM prices on 02 sensors were the cheapest around. I checked with Napa and auto zone which were way higher. Be prepared to spend at least 100 dollars for new 02 sensor. Besides the code do you know if its the front or rear sensor. Bank 1 or what?

I believe that's the same as mine was. I believe that's the front drivers side 02 sensor.

Check rockauto.com. They're pretty reasonable.

With the BBK long tubes this code issue is common. I just keep clearing the code out every so often
