Frequently Asked Questions

How much does a check engine light diagnostic cost for a 2005 Toyota Camry?

• Diagnostic fees vary by complexity; typical in-dealership scan and basic diagnostic often ranges from an economical flat fee to a modest hourly rate. Call for current pricing or check our service specials.
• We often cost less than independent shops when you consider accurate diagnosis, OEM parts, and factory-trained technicians — delivering both immediate savings and long-term value.
• If repairs are covered by warranty, they must be performed at a certified dealership to preserve coverage and ensure proper repair documentation.
• Our technicians use Toyota diagnostic tools to find the true cause quickly, reducing unnecessary parts replacement and overall expense.

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

• Start simple: confirm the gas cap is tight and undamaged — a loose or faulty cap is a common cause for this vehicle.
• Note vehicle behavior: loss of power, rough idle, or unusual noises provide clues and determine urgency.
• If the light is flashing, stop driving and have the vehicle towed to our dealership; a flashing light often indicates a severe misfire that can damage the catalytic converter.
• Bring the vehicle to Nalley Toyota of Roswell for a professional scan so our factory-trained technicians can diagnose and recommend cost-effective, warranty-compliant repairs.

What does it mean when the check engine light comes on in a 2005 Toyota Camry?

• The light signals that an engine or emissions-related sensor has reported a fault — it could be emissions controls, fuel delivery, ignition, or sensor failures.
• Common triggers include misfires, oxygen sensor faults, catalytic performance issues, or evap system leaks.
• Immediate diagnosis prevents secondary damage: unattended issues can lower fuel economy, reduce power, and lead to expensive repairs like catalytic converter replacement.
• Our dealership provides a full scan with Toyota-specific tools to identify the exact trouble code and recommend repairs with OEM parts to protect long-term value.

How long does a check engine light service take?

• Initial scan and code read can be completed in 30–60 minutes; a basic diagnosis is often same-day.
• Complex issues that require component testing, road tests, or parts ordering can take several hours to a day.
• We prioritize quick turnaround with OEM parts and factory-trained technicians, which often reduces total downtime compared with repeat visits to independent shops.
• For warranty-related repairs, having service done at a certified dealership ensures proper documentation and faster resolution without risking coverage.
