Engine light is on

Hey guys! New to the forum, as well as Taco ownership. Just bought an '01 Prerunner SR5 on 7/7 and love it! Always wanted one and got this for a great deal. It has 180,000 miles but still runs strong. Anyway, when I bought the truck, the check engine light was on. The salesman said that it was the O2 sensor, and that its common. Anyone know anything about it? It's a 2.7 btw.

Thanks in advance for the comments.

 

Most likely it is. Should have had them replace it before you bought it. It's not hard to replace. Run by a parts store and b have them check it out for you
