, FUEL TANK LEVEL, CHECK ENGINE LIGHT

2002 Mercury Sable

Mileage = 50,000
Engine = V6 3.5ltr DOHC
When the level in the fuel tank drops to approx 1/4, the Check Engine illuminates. I filled the tank to full and disconnected the battery. Engine light goes off until the tank gets to 1/4 and again the light comes on. Is there a fuel tank level sensor that could be faulty?

When the light is on go to autozone and have the codes read, if it's P0445 you may need a new gas cap!
