Why does the check engine light comes on saying the gas cap is loose or off when it is on tight.


Hi,
looks like there is a sensor on the filler cap/lid side.
which is faulty and not sending correct signal to the main computer in the car.

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.

I have a 2006 Saturn Relay with just over 70k miles. The "check gas cap" came up on screen after a few days the check engine light came on. was at a friend's who has a code reader and he...


The P0455 code indicates a leak in the evaporative gas system.

A loose, improprely seated, or defective gas cap will set the code in the computer.

Insure the gas cap is on and working as it should most caps gives a ratcheting clicking sound when seated. Inspect the cap for any damage and if found replace it.

If in doubt replace the gas cap.

P1456


code P1456 set when there's small leak in the fuel tank system.
Most known reason for P1456:
-Didn't tight fuel cap on until it click for more that 3 time after fueling up and drove the car too long with cap loose.
-or a bad gas cap.
I'll try tighting the gas cap.
clear check engine.
if code come back, replace gas cap and clear check engine light again.
