Have you driven the vehicle? Sometimes after battery replacement some of the dash lights illuminate but once the vehicle is driven they reset!

How do I reset my tire pressure light when tires are fine

My Lesabre has buttons on the left side of the dash. The one called Gage Info has a number of things like oil pressure check tire pressure heat Battery. Push this button till it says check tire pressure To reset your light push the reset button and hold for fifteen or twenty second and the light on the dash should go out and it will show tire pressure ok on the gage. Before you reset check all four tires for air as one tire could be down 8 or 10 lbs and the light will come back on. they all have to be the same pressure.
When you change your oil you should reset the oil section as well and hold reset the same as above. The oil section tells you how much oil you use over an amount of time.

Try disconnecting the Battery for 10 minutes or take it to an Autozone, Oreilys, Advance autoparts for a free computer wipe.

Okay, now for the bad news. If the gas cap solution does not work, you have an opening in the Emissions system somewhere.

There is a machine and process called a "smoke test". The special machine hooks up to your gas cap opening and forces a type of tracer smoke into the system. The leak will let the smoke out.

You could have a hole in the gas tank, or Emission lines. Many times an Emission hose will get caught when the vehicle is put on a service lift. If your problem happened after the vehicle had new tires put on it, or any type or work requiring the car to be raised off the floor, the hoist could have nicked a low hanging line.

Have a check engine Light and the shop says it is gas cap..reset check engine and all was well for about three weeks and back on again. Checked the gas cap and when you tighten the cap it continues to spin...

There is a rubber gasket on your gas cap, normally that is the problem. If it doesn't seal tight enough the tank isn't pressurized and that sets the error codes. You can either replace the gas cap or replace the seal or add another rubber gasket.

On my Lincoln, I was getting that code quite a bit, even after replacing the gas cap, so I added another rubber gasket and haven't had that code again.

Doesn't completely sound like a fuel pump problem...sounds like a vacuum line problem .... check your pcv ...and vacuum lines and when was your fuel filter last changed and how many miles are on the car...your fuel pressure regulator solenoid needs to be dry on the vacuum side too...diaphram could be leaking but if you can't find an obvious problem I would definiately find a qualified mechanic to dive into you have access to a scan tool to read the trouble codes?

I have a 2008 Mazda CX7 the light on the dash is on saying that my tire is low. I checked each tire the lowest is 23 the rest are about 29. What is the accurate tire pressure?

set all the tire pressures at 32-35 and drive the car as it may take a little time for the system to reset itself.there should be a decal on the drivers door that has the tire pressure on it.
