Yes, I believe some removet it in an effore to fool the buyer. You first must try to get the basics under control such as coolant, and brakes. Coolant could be in fact low or a bad sensor, same goes for the brakes, they have a little wear sensor on the pads that should be replaced anytime you replace the brakes, there like a couple bucks each US.
After that we can get into more aggressive fine tuning of your problems, post back as always!
