Check Engine Light?

\015 Have a 2004 GMC Envoy with a \342\200\234Check Engine\342\200\235 light that stays on. Mechanic says it due to a faulty \342\200\234Fuel Sensor\342\200\235, but the only information I can find is for \342\200\234Oxygen Sensors\342\200\235. He also mentioned that there were 3 sensors, but from what I\342\200\231ve read, there are only two.\015\012Is the correct item description Fuel or Oxygen Sensor?\015\012Are there 3 or only 2 on this make and model?\015\012Where are they located at and how difficult to replace?\015 Posted / edited by AnonymousUser on : 22-10-2018
