Oxygen sensor for a Chevy = $20 Oxygen sensor for an Audi = $150 !!!!! They look the same. Most sensors have a Zirconia element and operate between 0 and 1 volt. Does anyone know of a cross-reference between Audi parts and the more reasonable priced parts available at the local auto parts store?
"Q. Except for the connector assembly, aren't all oxygen sensors basically the same?
A. NO. There are five fundamentally different types of oxygen sensors: unheated thimble, heated thimble, planar, wide-band and titania. Within each sensor type, sensors vary in the design of the ceramic element, heater element and protection tube design, all of which affect sensor operation."
I guess I have an Heated Thimble on my 83 Audi 4000S, a Heated Thimble on my
91 Passat, and a Titania on my 88 Cherokee engine. Now I only need two more to complete my 5! lol
BTW the website above has a link for instructions on how to install a universal 02 sensor and also a Vehicle Part Finder link to find the univeral
I just recently replaced my O2 sensor. 96 S6 sensor $150 canadian. O2 sensor from 86 Mustang $45 canadian. Just had to snip off connector and splice wires.
