Any mechanics out there that know about emissions?

Question

i have a 1988 olds. 3800 and i,am getting a code 65. my hanes book says it is the 02 sensor. it says i,am losing contack at the plug in. can a person cut the wire and put a butt connector on it? also where is the engine coolant temperature sensor located on this engine? thanks for all your help.

Answer 1

Butt connectors will alter the resistance reading to the pcm, so this is not a good thing to do. The o2 sensor needs to be replaced in it's entirety.  The temp sensor is usually located in or around the thermostat housing.  Good luck.
