Climb under and look for leaks with a soap solution. I'm pretty good with p2099 chevy traverse mechanical things but electrical and sensors seem to drive me nuts. This is the sorta thing you really need the right equipment for.

The P fault code in automobiles indicates a problem with the Heated Oxygen Sensor HO2S circuit, which is responsible for monitoring the oxygen levels in the exhaust system. The repair importance is moderate, and the difficulty level is low. The repair time for this fault is approximately 1. The P fault code in automobiles can be caused by a range of issues, including a faulty oxygen sensor and exhaust leaks. To fix the p automobile fault code, check the possible causes and inspect related wiring harness and connectors for damage.

Our team of car experts has therefore provided you with this guide to solve the matter in the easiest way possible. Find out more about OBD2 codes research process. The P code indicates that there is a problem with the post-catalyst fuel trim system. This is the system responsible for adjusting the fuel-to-air ratio in the exhaust system to ensure that the catalytic converter is working properly. If the fuel-to-air ratio is too rich or too lean, it can cause damage to the catalytic converter, which can be expensive to replace. If left unchecked, it can cause damage to the catalytic converter and other parts of the exhaust system, which can lead to costly repairs.

The wording of the code has me running circle trying to figure it out. You'll also want a proper oxygen sensor tool. Log in. I find that, if you keep dialing in pressure above that, you end up making stuff leak that wouldn't under normal operation. Patched that but the code returned. Deals Forum. Explore Our Forums. I have a Traverse with a 3. Just get one that has decent graphing capabilities. If you do opt for changing your sensors just be forewarned that they like to seize up from rust. I've read that it could be the mass air flow sensor, fuel pressure regulator, vacuum leak somewhere, o2 sensors. I'm going to agree on this. They totally do get slower with age, no doubt.

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.

But they're usually cost prohibitive. Could it cause that code without setting any other codes? If you really enjoy this sorta thing and want to get better at it then I'd recommend getting the Autel MDElite. That way you have an extra set of freeze frame data so you can feel confident under what conditions this vehicle is flagging that code. Where does one go to find the pinout on sensor and the factory data perimeters for sensors voltage, Htz, etc? There is a correction limit, but you can never see if you're close to it or not. Powered by Kunena Forum. I really appreciate it. If you Google "Chev Traverse P" you'll come up with a lot of hits that say "post cat too rich bank 2". I usually dial in about 5 PSI, maybe 10 depending on how many leaks are in the system. As you can see, it's not a normal O2 code. Thank you both again. I don't have any experience with computer based scanner systems. Right now my plan of action is to figure out a way to plug the exhaust and pressurize it from the rear. Personally, I use an exhaust cone adapter with an air pressure regulator.
