Frequently Asked Questions

What is the most common reason for check engine light on a 2024 Toyota RAV4 Prime?

• Loose or damaged gas cap causing an evaporative emissions fault — an easy fix that often clears the light quickly.
• Faulty oxygen sensor or upstream emissions sensor — common with age and can affect fuel economy if not repaired.
• Engine misfires from ignition coils or spark plugs — left unchecked these can damage the catalytic converter and increase repair costs.
• Evaporative emission system leaks (EVAP) — hoses or purge valves can fail and trigger codes.
• At Bill Estes Toyota we diagnose the root cause with factory-grade tools and factory-trained technicians to avoid unnecessary repairs.

What does it mean when the check engine light comes on in a 2024 Toyota RAV4 Prime?

• It indicates a stored fault code from the vehicle’s powertrain or emissions systems; codes range from minor to urgent.
• Some codes are informational, while others signal problems that impact drivability, emissions, or fuel efficiency.
• A flashing light often means active misfire — immediate inspection is recommended to prevent further damage.
• We use Toyota diagnostic systems to read precise manufacturer codes and recommend repairs that protect warranty coverage.
• Repairs covered under warranty must be performed at a certified dealership to maintain coverage and ensure correct parts and procedures.

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

• Check the gas cap for tightness and visible damage — a loose cap often triggers an EVAP code.
• Look for obvious signs: smoke, odd noises, loss of power, or fluid leaks — these indicate urgent service needs.
• Note recent fuel, service, or fueling incidents to share with our technicians for faster diagnosis.
• If symptoms are mild, schedule a certified diagnostic at Bill Estes Toyota so factory-trained techs can confirm the code and recommend the right repair.
• For warranty-covered repairs, having service performed at our dealership ensures full compliance with Toyota warranty requirements.
