Frequently Asked Questions

What is the most common reason for check engine light on a 2024 Toyota Venza?

• Loose or damaged gas cap causing an EVAP system fault — an easy, inexpensive fix.
• Faulty oxygen sensor or mass airflow sensor, which can affect fuel economy and emissions.
• Engine misfires from worn spark plugs, coils, or fuel delivery issues; left unchecked these can damage the catalytic converter.
• Catalytic converter degradation due to prolonged misfires or contamination.
• Our factory-trained technicians diagnose root causes quickly, often saving you money now and over time compared with delayed repairs.

How much does a check engine light diagnostic cost for a 2024 Toyota Venza?
