Weird SWPS Issue

I have had my SWPS replaced twice, so I know what to look for when it goes out. However, my issue is that it throws the 1287 code only in the mornings, if it is wet, damp, or humid outside. Once I resest it, it does not come back on no matter how long it sets or how long I drive it. When I leave work, if it is wet, damp, or humid outside, it does not throw the code. If it is hot and dry ouside, like it is here in the summer, it won't throw the code in the morning.

Any ideas on what may be going on? I don't want to replace it again if it really isn't needed.

I agree. Check and clean your grounds. The two on the front rails mostly.

Thanks for the input! Looks like I will be cleaning some grounds this weekend.

Well, I cleaned both grounds on the front rail, which were not bad looking at all, and still had the problem this morning. From post #2, it looks like it may be linked to ground 201, which is at the bottom of the A-pillar.

How do I get to this ground?

I know this will come to me after I hit reply, but what the heck is SWPS?

Ok, I have been searching to find out exactly how and what to remove. Does anyone have step-by-step instructions? I am afraid of damaging this high dollar plastic.
