1999 Lincoln Town Car (Check Engine Comes On)

The check engine light has come on on my 1999 Lincoln Town Car. I have checked the gas cap and the car seems to be running alright. What could be some of the other causes for this? The gas filter has been changed on the car also.

You have to get a reading of the on board diagnostic system, Autozone read it for free . then they will print a code for you that will show which part is causing the problem (oxygen sensor or the catalytic converter )

I put regular gas in my 1999 lincoln town car and now it's running rough, what do I need to do?


Is the check engine light on ?
Normally the computer will try to change the timing to compensate for the lower octane of the fuel. Once you use half of the tank you could put premium in and mix it.
But if the check engine light is on and you have a miss, the problem could be something other than the cheaper gas.

2001 lincoln town car check engine light on code 457 what's wrong??


Code 457 is for a leak found in the evap system which vents the gas tank to the vapor canister. The gas cap could be loose, or damaged. Or there could be a leak somewhere in the tank vent or lines.

What would cause the Check Engine light to come on with a P0455 Code on a 1997 Lincoln Town Car?


There is a leak in the gas tank vapor system. Most of the time it is the gas cap but can be a hole in the tank, filler neck, or lines to the motor, not the gas hose but the vapor hose.

Check Engine Light


If you just put gas in the vehicle it may be as simple as not tightening the gas cap tight enough. This would trip for emissions and cause check engine light to come on. Worth a shot! Tighten the cap and drive see if goes off. Could also be carbon build up blocking the egr valve. Since an older person had the vehicle prior and likely didnt get on the gas much this would build up.

When I'm on the road my check engine light comes on but it happens at different times, sometimes it never comes on or sometimes it comes on a few miles down the road. when I turn my car off then turn it...


The most common cause of this is the gas cap not being tightened completely after re-fueling or a worn rubber gasket on the cap.Remove the gas cap and turn it over and check the gasket if it looks like it's not worn put the gas cap back on and then tighten it until it clicks several times, then it make take a little while before the check engine light goes off. If this still happens shortly after tightening the gas cap have the check engine code read at an Automotive Parts store. Some stores have the code readers and they'll get what the code means and advise you at that point.

2000 Lincoln Town Car (Engine Service) found a EVAP System?


Check your gas cap. If someplace can test it you might luck out. This website advertises manuals and info online. The evaporator cannister is suppose to purify excess fuel vapors. But a system which is not sealed will code an error lamp.
