P1899 fault code on 2000 Plymouth Neon

I got a p1899 fault code during my smog test. The engine fault light is on but goes out when i fill the gas tank or apply any heavy load on the car or when the gas tank is almost empty. Any suggestions on how to fix the park/neutral switch

This code seems to be related to the park/neutral safety switch, so that will need to be checked out. Probably needs to be replaced or adjusted. I would get a good repair manual to learn how to troubleshoot this or take it to a shop and have it done for you. http://bit.ly/mitchell_repair_manuals_online http://repairpal.com/directory?address=95307&car_brand_names=Plymouth
