Does anyone know what the proper resistor would be to put into O2 sensor to get the check engine light to turn off? I have no cat on my car. RKSport sells one that looks all pretty but they want like $68 for it. Thanks!

you want to do what. Did you try to put an O2 sensor back there. Casper makes a bug that is supposed to simulate the O2 without being there but it still trows codes becasue of the temp or something,

here you go read this. it's form the local car club

you cant just put a resistor in and think itll work. an o2 produces voltage so you would have to use a simulator if you dont want a downstream o2.

The resister may cause more problems and make your car run ruff. Not a good buy in my opinion.
