I apologize up front for my lack of of tech knowledge. I have a stock 40th Ann. Edition and I use it as a daily driver. Yellow dash light comes on. Owners manual says this means there is an electrical problem. Go to local dealer and they say it is a bad CO2 sensor and will cost 300+ to replace. I tell them to go ahead. They then call and say they can't get the sensor out because it is on a stud and if they try to take it out it will break off and that they need to replace the whole catalytic converter for 1600. I tell them "no" partially because I don't trust them 100% but mostly because 1600 is crazy.
Anyone know how this stuff works? LC runs fine even with the dash light on. What does the sensor do? If I don't replace it, what is the down side? Will it stop me from passing emissions test? Do the $$ numbers sound right from the dealer? Is this light (it is the yellow one on the dash, for the life of me, I can't figure out what shape it is supposed to represent by the owners manual says it means you are out of gas or have an electrical problem) indicating an electrical problem other than the sensor or does it sound to you like the sensor is the problem? If it is the sensor and it is stuck, is there a way to fix it without replacing the whole catalytic converter?
TIA for any input. I have some time to fix this and would appreciate help.
