Had the dreaded PO133 code and failed smog. So I purchased a new Denso part #234-4161 as per Denso site. The connection was impossible to get to. Right on top of the std. Tranny. The two nuts came off the manifolf np. There was no way of disconnecting it from below. I was pretty proud of myself for coming up with a solution. See attached. I removed shift lever boot and low and behold there it was. 15 minutes latter buttoned up and good to go.
Cleared the re-test with flying colors!
Hope t his helps someone
