    First time posting. I have a 2011 Tacoma 4wd 4 cylinder with 137,000 miles. Purchased the truck new. Driving today and the check engine and traction control lights both came on at the same time. This is the first time that either light has ever been on! Stopped by the parts store and had them hook it up for codes. Came back with P014C, P014D, and P2196. I had them clear the codes but they came back on before I got home. Is it safe to continue driving? What is the most likely culprit? Any help is greatly appreciated.

    Most likely the AFR (Upstream) Sensor has failed but it's possible there's a base fuel issue, impossible to tell for sure without further testing.
    I wouldn't drive it far like that as you could damage the catyletic converter if the air/fuel ratio is too far off.

    They look pretty good, the middle 2 may be running a bit lean but I wouldn't worry about it too much until you get the AFR sensor issues straightened out.

    Stuck the plugs back in, replaced AFR sensor, and cleared codes. Drove it around for a while and no lights came on. Thanks for your input!!! Here is a couple pics of AFR sensor that I pulled out. 20240425_193932.jpg 20240425_193917.jpg
