What does it mean when the check engine light comes on in a 2022 Toyota Tundra?

What is the most common reason for check engine light on a 2022 Toyota Tundra?

• The most frequent causes are sensor-related: oxygen sensors, mass airflow sensors, or EVAP system leaks. These often trigger emissions-related codes first.
• Left unaddressed, small sensor faults can lead to richer fuel mixtures or misfires, raising fuel costs and risking catalytic converter damage.
• Bringing your Tundra to our dealership ensures accurate diagnosis, OEM parts, and warranty protection that independent shops can’t always guarantee.

What is the first thing to check when the check engine light comes on?

• Start with basics: confirm the gas cap is tight and undamaged — EVAP system codes often result from a loose or missing cap.
• If the light stays on, have a certified diagnostic scan performed. Our service team at Bill Estes Toyota uses OEM scanners to read and interpret codes accurately.
• For warranty-covered issues, repairs must be done at a certified dealership to preserve coverage — scheduling service with us protects both your truck and your warranty.
