Frequently Asked Questions

What does it mean when the check engine light comes on in a 2021 Toyota Sequoia?

• Addressing the codes quickly protects engine performance, fuel economy, and long-term reliability. At our dealership you’ll find factory-trained technicians, OEM parts, and transparent pricing that often costs less than independent shops while delivering superior service and immediate and long-term savings.

• We offer service financing to help you get repairs now and pay later, and you can schedule service online any time.

What is the most common reason for check engine light on a 2021 Toyota Sequoia?

• The most frequent causes are related to emissions systems: oxygen sensors, catalytic converter issues, or an evaporative emissions (EVAP) system fault often caused by a loose or damaged gas cap. Less common but important are ignition or fuel system faults.
• Ignoring these warnings can reduce fuel economy, increase emissions, and cause expensive damage over time. Our certified technicians at Larry H. Miller American Toyota Albuquerque diagnose and repair these issues with OEM parts and factory procedures to protect vehicle value and longevity.
• We emphasize transparent estimates, warranty protection, and the cost advantages of correct OEM repairs performed by trained technicians — plus financing if you need it.

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

• Start with the simple checks you can do safely: ensure the gas cap is tightened. A loose cap often triggers an EVAP code. If the light remains on or is flashing, you should get a professional diagnostic right away.
• At our dealership we use manufacturer-level tools to read codes and determine severity. If the check engine light indicates an urgent fault, we recommend you schedule service immediately to prevent further damage.
• We back every repair with clear documentation, OEM parts, trained technicians, and the option of service financing so you can make the best decision for safety and long-term value.
