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

• The light indicates the onboard diagnostics (OBD-II) system has logged a trouble code — causes range from minor (loose gas cap) to serious (misfire or catalytic converter issues).
• Common triggers include emission-sensor faults, ignition/misfire events, evaporative system leaks, or exhaust catalyst efficiency problems.
• At Toyota of Greenville we use factory-level scanners to read codes precisely and recommend the correct repair, minimizing unnecessary parts replacement and saving you money over time.
• If the code is covered by warranty, repairs must be performed at a certified dealership to keep coverage intact.

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

• Start with simple checks: ensure the gas cap is tight and inspect for obvious signs (leaks, low fluids, unusual noises).
• If the light persists or the vehicle runs poorly, record any symptoms (loss of power, rough idle) and avoid heavy towing or performance stress.
• Bring the vehicle to Toyota of Greenville for a prompt scan; our factory-trained technicians can often diagnose the cause quickly and recommend cost-effective repairs.
• Remember: repairs covered under warranty must be performed at a certified dealership to preserve benefits and ensure factory-quality service.

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

• Common reasons include loose gas caps, oxygen sensor faults, EVAP system leaks, ignition misfires, and catalytic converter efficiency issues.
• Many of these begin as inexpensive repairs but can escalate to costly failures if left unaddressed — e.g., unattended misfires can ruin a catalytic converter.
• Tackling problems early at Toyota of Greenville often costs less than delayed fixes and protects long-term vehicle value and performance.
• For any warranty-related diagnosis or repair, the work must be completed at a certified dealership to maintain coverage.

How long does a check engine light service take?

• Initial code retrieval and basic diagnosis typically take 30–60 minutes; more complex issues can require several hours or multiple visits for road testing and component checks.
• Simple repairs (gas cap, sensor replacement) are often completed same day; more involved repairs (fuel system, catalytic converter) depend on parts availability and inspection results.
• Toyota of Greenville’s parts access and factory-trained technicians often shorten repair time, offering quicker turnaround and reduced downtime compared with slower parts sourcing elsewhere.
• If a repair is warranty-covered, it must be done at a certified dealership; we’ll schedule and prioritize accordingly to get you back on the road promptly.
