1999 Camry P1780 Code

by bxkid, July 13, 2017


I have a 99 Camry with 112,000 Miles and inspection coming up. P1780 code showing Park Neutral safety switch problem. Cleared code but came back at 101 miles.

Wiring looks good in trunk area, at wires along conduit.

There is a crimp repair on white wire in trunk, but looks secure. I guess previous owner had issue.

Cleaned connector on Neutral safety switch before clearing code.

All lights work correctly.

Car starts in park and neutral, but not in other gear settings.

No other error lights on except check engine light.

Here in Delaware, they will not pass inspection unless check engine light is out!

Thanks for any advice on this matter.
