Way too many variables. Could be that it just passed the monitor for bank 1 and only bank 2 went past the threshold for flagging a code. I've learned a few things this weekend, p2099 chevy traverse.

.

It has the same meaning for the Chevy Traverse as it would any other vehicle. It specifically indicates that your Traverse detected that air-fuel mixture reading as the exhaust gas exits the catalytic converter on the bank 2 side of the engine is too rich. There are three main parts to the defintion of P They are color coded above, and each section is defined seperately. Post catalyst means whatever is happening is after the catalytic converter in terms of exhaust flow. The fuel trim system is what your Chevy Traverse uses to adjust the air-fuel ratio for optimum combustion.

This is one of the most frequent OBD2 trouble codes. Read the full article below to know what it means, how to fix it, and what other codes may show related to it. Engine exhaust gases are pushed through the exhaust manifold, into the exhaust pipe, and through the catalytic converter as spent engine Exhaust Gases. The ECU then goes on to incorporate the downstream O2 sensor into the equation. When the bank 2 downstream O2 sensor circuit input readings are too few oxygen molecules, a P code will be stored and the indicator lamp for this fault may be illuminated. The following are some of the most common mistakes that a technician may make when diagnosing a P code:.

I'm tired of depending on others to fix things so I"m going to try and chase this down. Tyler wrote: Being fair to your mechanic and the dealer, but this can be a very tough code to reproduce reliably. That's why you gotta get an idea of how it's running.

Now, I did have to replace one of the cats, but the entire job cost less than the dealer wanted to just replace both catalytic converters I consider it a pretty safe test overall. If you Google "Chev Traverse P" you'll come up with a lot of hits that say "post cat too rich bank 2". Log in Forgot your password? Thank you ecwurban for that. I've started looking at PC software. Way too many variables.

We recommend Torque Pro. Note that since diesel engines almost always run with excess air, this generally does not apply to diesel engines. Nevertheless, to understand code P and why it sets , it is necessary to understand that the correct functioning of the upstream oxygen sensor is directly related to what happens after the exhaust stream enters the catalytic converter.

Just passing the info on. I usually dial in about 5 PSI, maybe 10 depending on how many leaks are in the system. Now when you get an idea, before you even test it, ask yourself if it'd have the same characteristics as what your vehicle has. Sort by Oldest first Oldest first Newest first Most reactions. This is an older thread, you may not receive a response, and could be reviving an old thread. Log in. If I had this vehicle I'd want to look at engine data and get a baseline of fuel trims and O2 data under different load conditions. Could be that it just passed the monitor for bank 1 and only bank 2 went past the threshold for flagging a code. You just always have to ask yourself what you can do to narrow down your search or at least make your search more clear. But they're usually cost prohibitive. Powered by Kunena Forum.
