2003 VQ35DE with Drive by Wire
I took off my intake for regular maintenance, as well as changing spark plugs. To clear room, I disconnected the TPS sensor on the Throttle body from its harness. Last week i started putting stuff together, and the TPS harness won't go onto the TPS plug.
I need insight on whether the harness is broken, damaged, or if my methods are inadequate. But first pictures, so that you all will have a better idea of what I'm talking about.
This is the Harness:
This is the plug on the TPS:
Here's what I know so far: The springs (you can see their white/clear tops in the top section of the harness) are contacting the guides on the TPS (the two guides with the rectangle between them in the last picture). I cannot push the springs far enough out of the way to change this. Even after lubricating the springs and TPS plug, I can't get the springs to slide past the guide. This contact causes the sliding/locking mechanism on the backside of the harness to get pushed back when sliding the harness onto the TPS plug. Or, if you slide the locking mechanism all the way back, put the harness on the TPS plug, and then try and push the locking mechanism all the way forward, the TPS plug gets pushed off the harness. It was my initial assumption that the springs are supposed to slide past the guides, but I'm not super confident on that.
So, lets say the springs are supposed to contact and push against the guides. If that's the case, then fine. I'll push harder, but I've already poked holes in backside of the sliding mechanism from pushing with a flathead screwdriver.
If I take the springs out of the harness, it doesn't lock onto the TPS plug with any force other than the friction between the two surfaces. I can pull the harness off without touching locking/sliding mechanism on the backside of the harness.
The harness appears to be in working shape and not damaged, nor do I recall any snapping noises when I pulled it off the TPS plug last week. When just inspecting the harness, if I push the locking mechanism all the way forward, it clicks into place, seeming to suggest that it works.
Any insight is greatly appreciated, as my truck has now been sitting in the driveway for a week. I'd have to tow it to a shop or drive it to one with the TPS harness shoddily connected, and I'm not sure what a shop would do or tell me to do at this point.
