Banks Running Rich on 1&2

My 2014 Toyota Tundra with 124k miles on it keeps popping that banks 1&2 are running rich. Also on the menu screen it keeps showing the words traction control off. I’ve replace wheel speed sensors, O2 sensors, MAF sensor, all spark plugs. I have an issue of losing oil as well. I cannot figure out what to do next.

 

Is there anything done with the intake or is it 100% stock?

 

Running rich on both sides may be intake related. You may need to run diagnoatics and see what your fuel trims are looking like. Losing oil may be an issue, if the cam tower leak is pretty bad. What oxygen sensors did you replace? Pre-cat or post-cat?

 

It’s all new to me working on the truck. The only O2 sensors I could find were four of them and they were on engine side of catalytic converter. The intake appears to be stock. I bought it used about a year ago.

 

Understanding it's operating in open loop?? Even though the truck is operating on normal temperature?? This would mean the ECU thinks the truck is still cold and not getting feedback to close the loop and have the truck run normally. Either an O2 sensor is incorrectly wired up, or they may be bad out of the box.
Do you know of any mod it may have??

 

No I don’t. The check engine light and the traction control has been off the last couple of days since I been letting it run before leaving. Seems that when I use the auto start and let it run for minimum of 5 min it does fine. If I was to get in truck and start it and leave shortly after the check engine light comes on for the too rich codes. When I ran the freeze frame it all showed closed loop.

 

It sounds like a heater wire issue on the oxygen sensors, not sure if you're getting a code on just 1, or both banks. Maybe the heater wire is slightly loose or losing contact when you jump in and start it, since that's when you're having the issue. The remote starts allow them to keep contact and warm up normally. I may sound stupid, but the only difference between getting a code and not getting a code is you technically jiggling the wiring while getting in the truck and closing the door. May sound like wiring is exposed or not properly soldered/mated together and losing contact, depending on how they were mated. I'm assuming since we're not getting any ocular pleasure, additionally assuming universal oxygen sensors come with loose wires that have to be trimmed and soldered together. I've had bad experiences with the Bosch sensors on my Celica, so I've had to bite the bullet and swap them out with Denso sensors and had better luck with them. My issue was the heater wire would not have enough time to heat up, so I was running rich most of the time so it would run open loop, until I gave in and swapped the sensors out, but I did get a specific code on open loop, besides the O2 code

 

Thank you! I will definitely look into this.

 

Did you ever find a fix for this? I’m currently getting bank one and two running rich aswell as the traction control off
