    What check engine light? It looks TPMS related... Or you have a flat tire or one of the sensors is broken.

    TPMS = Tire Pressure Monitor System.

    Either one or more tires are low pressure, or the battery is failing on of the sensors. The sensors are in the tires, at the inside end of the tire valve. The batteries are not easily replaceable. The sensors can be replaced, and the system re-calibrated, typically by dealership, though I think tire shops may handle it too. It's not cheap though.

    Check your tire pressures, make sure they're all slightly above your usual setting, see if the light goes out. If it doesn't, you can look into replacement, or just live with it.

    It was tire pressures. How do I prevent my catalytic converter from being stolen? Heard someone at work got theres stolen.
