P0850: Neutral Safety Switch on an MT

MarksZ34 · 10-26-2016, 12:45 PM

I'm getting this code but there are absolutely no issues with starting, running, gear selection, gear indicator, etc. I plan to take a look to make sure there isn't a loose connection and I'd like to also change the switch while I'm there just to make sure I fix the problem.

Has anyone done this on an MT? Can I do this without removing the tranny, exhaust or anything else?

TIA for any replies!

not sure on Z but all my other cars had the neutral switch connected to the clutch pedal...somebody will chime in

probably a switch near the clutch pedal that compresses when you step on the clutch pedal. Maybe a loose connection there.

That is the code for the park/neutral switch located near bottom of shifter. FSM will have diagnosis and R&R procedures.

Edit: Switch may be located somewhere else and I'm thinking of lockout mechanism. FSM will tell ya.
