winterset Posted October 28, 2011 Report Share Posted October 28, 2011 Finally replacing my O2 sensor. Got the old one out (the one right up against the firewall). old one says AFS 109 New one is an AC delco AFS 109. electrical plugs are the same, but the sensor itself looks totally different. The old one has slits at the tip of the sensor where it sticks into the manifold collecting oxygen readings, and the new one has a bunch of holes. Also the old one is a solid stainless tube (looks like a deep socket), and the new one is much thinner at top (resembles a spark plug). anyone know what happened? - did GM really change the design THANKS Link to comment Share on other sites More sharing options...
