2000 Plymouth Neon Question: P1899 fault code



, Ceres, CA, July 03, 2010, 19:34

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.
