- Park/neutral position switch circuit poor electrical connection
The park/neutral position (PNP) switch includes a transmission range switch. The transmission range switch detects the selector lever position when the shift lever is in the N or P shift position and sends a signal to the Transmission Control Module (TCM).
The Solenoid "E" is inside the tranmsission. Since you are having both a open and low code, the solenoid itself is bad. I suggest taking the vehicle to a trained transmission repair service for that solenoid isn;t easy to change out. The valve body has to come off and that takes someone with experience to put it back on with no issues.
The park/neutral switch, it should be mounted on the exterior of the transmission where the cable meets the transmission, driver side, neat the front and top, just on the edge. It is easy to change out. You remove the cable and the 2 bolts holding it on and replace. Not much to that one.
If you look on the side of the transmission, there should be a data plate. If I can get the model of transmission you have, I might have instructions for the solenoid replace. There are 5 different auto transmissions used so having the right info will help out.

I do have many workshop manuals, diagrams, etc that I pay to get access to out of my pocket. If one is needed, please ask and I will give
you an offer at my technician discounted cost to you for such manuals. I never charge above that cost.
