Frequently Asked Questions

What is the most common reason for check engine light on a 2006 Toyota RAV4?

• Loose or faulty gas cap causing an EVAP system fault — an easy fix that often clears the code.
• Oxygen sensor or heater circuit failures, which affect emissions and fuel economy if not addressed.
• Ignition misfires from worn spark plugs or coils, leading to rough running and potential catalytic damage.

What does it mean when the check engine light comes on in a 2006 Toyota RAV4?

• The light is a general indicator that an emissions or engine system has reported a fault to the vehicle’s computer.
• It can range from a minor issue, like a loose fuel cap, to serious problems such as misfires or catalytic converter failures.
• A steady light usually allows limited driving; a flashing light signals immediate attention is needed.
• We recommend scanning the code promptly to identify the issue and prevent further damage or higher repair costs.

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

• Verify the gas cap is tight and properly seated — this simple check resolves many EVAP codes.
• Look for obvious issues: smoke, unusual noises, or severe performance loss that require stopping the vehicle.
• If the light is steady, schedule a diagnostic scan to read stored codes and determine the next steps.
• If the light is flashing, reduce load and have the vehicle inspected immediately at our dealership to avoid engine damage.

• Basic diagnostics often take 30–60 minutes to read codes and perform a visual inspection.

• We provide a clear time estimate before work begins, and our factory-trained technicians work efficiently to minimize downtime.
