Frequently Asked Questions

What is the most common reason for check engine light on a 2013 Toyota Sequoia?

• Loose or damaged gas cap causing an EVAP system leak — the simplest and most frequent cause.
• Oxygen sensor or EVAP sensor faults that affect fuel trim and emissions.
• Engine misfire (spark plugs, ignition coils) that triggers emission and performance codes.
• Catalytic converter degradation after prolonged driving with unresolved issues; expensive if left too long.
• Bring the vehicle to Bill Estes Toyota in Indiana for an accurate code read; certified dealership service often costs less than independent shops over time and preserves warranty coverage — warranty repairs must be done at a certified dealership.

What does it mean when the check engine light comes on in a 2013 Toyota Sequoia?

• The vehicle’s onboard computer has detected a fault in the emissions, ignition, fuel, or powertrain systems.

• An error code is stored and must be scanned to identify the underlying issue accurately.
• Early diagnosis at Bill Estes Toyota allows factory-trained technicians to fix problems correctly, often resulting in lower total cost of ownership than independent shops.
• If a repair is covered under warranty, the repair must be completed at a certified dealership to maintain coverage.

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

• Confirm the gas cap is tight and undamaged — a loose cap is a common, quick fix.
• Look for obvious issues: low oil, coolant leaks, frayed wiring, or disconnected hoses.
• Note any new noises, loss of power, or rough idle and avoid prolonged driving if symptoms are severe.

How much does a check engine light diagnostic cost for a 2013 Toyota Sequoia?

• Diagnostic scan fees typically range from modest flat rates to slightly higher depending on depth of testing; many dealers and shops quote between $80–$150 for initial scanning.

How long does a check engine light service take?

• A basic code scan and initial inspection typically takes 30–60 minutes, depending on technician availability and symptom complexity.
