Park Neutral Switch help! Engine code p1780

Ok so I have engine code p1780 which in the park Neutral switch..
Got it replaced with a new sensor, and the engine code went away.
But after starting the truck 3-4 times it came back on.
Needs to get smogged soon and won't pass with this engine code!
Any help is appreciated

Not trying to be a smarty pants but.... you need to find out the reason the sensors are going bad, have you checked the grounds and wiring of that system?

No offense taken dude. Any help is really appreciated. Checked grounds and looked good, wiring looked good I think. Ill double check but looked good to me.

Think parts cleaner on the clip that goes to the sensor would fix my issue?

MAF Cleaner? Hmm i was going to pick up some Electric parts cleaner but its probably all the same.
Uhm clip looks alright, definitely tight. It was near dark when i was swapping parts, the inside of the clip might be pretty dusty
