Check engine light after replacing Upstream O2 Sensors
Hey all,
Recently, I was getting a Mixture Control 2 CEL on my 2013 X5 Xdrive50i. Figured it was the O2 sensors so I went ahead and had them changed out with Walker O2 sensors on the Upstream side. Both of them. Well, now I don't get the mixture control 2 CEL anymore but the following. Should I have gone the BOSCH OEM sensors instead? Is there something I'm missing here? Looks like I'm getting codes from both sensors malfunctioning now. Any help would be greatly appreciated. See below. |

This is just a guess but my experience on the Lexus ISF platform is using Walker O2 sensors had the same issues and the advisory was stick with OEM Denso.

So I switched to the OEM Bosch sensors and all is well. Only problem is that I am now getting the original Mixture Control 2 error. Any idea what else could cause this?

What's the actual code you're getting now? And you may be able to reset adaptation by unplugging the battery for 2 mins or so. |

This was the original reason I decided to change out my upstream sensors. Funny thing is when I installed the Walker sensors to start, I started getting the errors I noted previously and this one had gone away. Thoughts? |

That shows up as System Too Rich (Bank 2) Try to swap bank 1 and bank 2 sensors, see if the code travels to bank 1 (with the sensor). |

The issue was presenting itself before I changed the upstream sensors and I'm getting the same code after 2 brand new sensors. I don't think switching sensors is going to make a difference at this point.
