Neutral Light On At All Times, Even If Car Is In D

[pardesi]

Hello everyone.. I have a 98 GS300. Couple weeks back when it got below 25 degree weather in Minnesota my Neutral light on the dash lit up, even if I was in Drive and other gears. It went away that day but now it's back and the check engine light comes on as well. I had it diagnosed from one place and got the following code P1780 (Park and Neutral Switch malfunction). But finally took it to Lexus dealer today and they also did a diagnostic and didn't find any error codes and said that PNP switch is working just fine. They are wanting to take the gear console apart to see what wrong with it and charging good deal of money. So I need some help here to figure out what I can do. I tried resetting the ECU, but the check engine lights comes back on after a while.

If anyone has encountered this problem in their Lexus or have suggestions, let me know...

Thanks, Pardesi

if the place first read the code then it would have been cleared after

it may only be under cold conditions it acts up but it sounds like you need a new switch
