98 Dodge Ram 1500 Sport throwing P1899 Park/Neutral Switch.

Not sure what causes this one or what some symptoms of it are. I know I have a reverse light out, but beyond that, it runs fine. Also not getting a CEL.

 

Will it start in reverse or drive? If it does then I'd replace the switch.

 

i dont know - i've never tried it. it starts in park, which is how i generally start it.

i'll try that later though. how difficult is the switch installation? aside from starting in drive or reverse, will this switch being faulty cause any other issues?

i currently dont have cruise, and i cant get the overdrive dash light to go on, so im guessing either this code has something to do with that, or i have a vac leak somewhere.

 

P1899 P/N Switch Stuck in Park or in Gear . Not a big deal, except you don't want to start it in drive or reverse by accident.

And yes the cruise is usually a vacuum issue. There is a tube that runs under the battery tray to the module/servo. Check it.

 

is the overdrive not working generally related to either of those issues?

 

Did you read my last post or what?

 

got the code. changed to switch, and still have the problem. never had a problem starting in park or neutral. rev limiter dropped and cruise control is offline persay. everything else works fine. i checked the switch with a meter and it seems to be fine.... any ideas

 

You have a short somewhere.

 

Check at the plug itself. The middle pin should be grounded when the shift lever is in park, or neutral, and open when in any other gear. Looks like the other two pins are for reverse lites.
