I'm getting codes P0446 and P1633 about which this post and this post say check fuse 24, which I did and it's OK, and I thought that cured the problem, but it turns out it takes a bit for the CEL to come on so I still have the problem. There is 12V at the fuse and the fuse is good.
So next step is to check pin 45 on the C175b connector at the PCM, but I want to be sure before poking around the PCM. I believe C175b is the middle connector of 3 on the PCM, and I can see the label on the connector that says pin 1 on the connector is at the bottom toward the outside of the vehicle. The wiring diagram shows this:
and this for the connector locations
which looks like C175t and C175e end up someplace different from C175b, but apparently not, they're all on the PCM. And it has this for the connector layout:
so from the back (wire) side the pin layout would be like this:
and this is what the PCM looks like:
So pin 45 should be on the middle connector, second from the top, below the green/blue wire, on the fourth column in from the fender side (not the column that only has 4 wires in it). Right?
