Intermittent PO133 code...

[masphx]

For about the last 200 mi my UG scanner has been picking up a pending PO133 code. It goes away soon after though so it does not become an active CEL. This is the O2 sensor right or is it something else? Where do I get a new O2 sensor for the best value if that is the solution?

Thanks,

Mason

Hi Masphx,

Check - Underdog Racing Development o2 sensor chart for your engine/transmission combo application. I've found amazon to have the best prices, and used vendor " tritan direct " for the front/rear o2 sensors both shipped were $113.

Hope this helps........
