Loose gas cap: A loose or damaged gas cap can trigger the "service engine soon" light to turn on.

Can a loose gas cap cause a check engine light?

Yes, a loose gas cap can trigger a check engine light, according to an article from AutoPadre. It is noted, however, that initially, the impact of a loose gas cap is minimal. If left unaddressed, it can cause harm to the environment, affect fuel economy and damage the emissions system.

Why is my gas cap not working?

The gas cap may not be working due to a loose or damaged O-ring inside it, which can cause it to remain permanently loose if it is old, dried out, or cracked. Another reason could be a faulty pressure release valve, as the gas cap plays a crucial role in not just sealing the gas tank but also regulating pressure.

What does a loose gas cap have to do with cel?

A loose gas cap can cause the check engine light (CEL) to come on. This issue typically occurs when you forget to properly tighten the gas cap after getting gas at a gas station. It is important to check the gas cap first if the CEL comes on after getting gas.
