Question about 2004 GMC Envoy
Have a 2004 GMC Envoy with a “Check Engine” light that stays on. Mechanic says it due to a faulty “Fuel Sensor”, but the only information I can find is for “Oxygen Sensors”. He also mentioned that there were 3 sensors, but from what I’ve read, there are only two.
Is the correct item description Fuel or Oxygen Sensor?
Are there 3 or only 2 on this make and model?
Where are they located at and how difficult to replace?
There are 3 one on each side of eng. on the Y pipe one behind the cat. convertor. not to hard change
