What is the first thing to check when the check engine light comes on for a 2026 Toyota Tundra?

• Check for obvious issues first: loose or missing gas cap, low oil level, or recent fill-ups with different fuel. These quick checks often resolve simple triggers.
• If those are fine, get an OBD‑II scan to read stored codes. A scan identifies whether the condition is urgent or routine and guides next steps.
