Question about 2003 Mercury Sable
My Sable gas cap light came on today and stays. I have removed and checked the cap, looks OK I have cycles the engine several times and the cap light comes and stays on.
Make sure that the gas cap have a rubber gasket in it if it has accidentaly dropped off while you removed to fill the tnk it will not seal properly and create a vacum leak causing the ecm to turn on the light.
or did you have an accident or did you run over any thing that could have damaged the vapor canister at the bottom of the vehicle and if this is the case you will see the light on because a damaged canister can cause a vacum leak
