Frequently Asked Questions

What is the most common reason for check engine light on a 2025 Toyota Land Cruiser 1958?

• Most often the light is triggered by emissions-related issues: a loose or damaged gas cap, an EVAP system leak, or an oxygen sensor fault—each ranges from inexpensive fixes to moderate costs if parts are required.
• Other frequent causes include ignition misfires (spark plugs or coils) and turbo or boost-related sensor faults given the 2.4L turbocharged engine; left unaddressed, these can lead to higher repair costs and reduced fuel economy.
• Using premium unleaded fuel and timely service reduces long-term wear on turbo, sensors, and the catalytic converter—saving you money over time.
• Warranty considerations: repairs covered under warranty must be completed at a certified dealership. Nalley Toyota of Roswell often costs less than independent shops while providing factory-trained technicians and superior long-term savings.

What does it mean when the check engine light comes on in a 2025 Toyota Land Cruiser 1958?

• The light indicates the vehicle’s onboard computer detected a system or sensor fault—this can affect emissions, engine performance, fuel system, or drivetrain components.
• A steady light usually means a non-immediate issue that should be diagnosed soon; a flashing light signals an urgent problem requiring immediate attention to avoid engine damage.
• Only a diagnostic scan can identify the trouble codes and the correct repair path; Nalley Toyota of Roswell uses factory-level tools to read manufacturer-specific codes for accurate repairs.
• For covered repairs, warranty work must be done at a certified dealership—this preserves coverage and often delivers immediate and long-term savings compared with independent shops.

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

• Start with the simplest: ensure the gas cap is tightened. A loose or damaged cap is a common trigger and an easy fix that may clear the code.
• Check for obvious performance issues—loss of power, stalling, or strange noises—and inspect the dashboard for related warnings that indicate more urgent concerns.
• Verify fuel type: the 2025 Toyota Land Cruiser 1958 requires premium unleaded; incorrect fuel can affect engine sensors and performance.
• If the light persists or flashes, bring the vehicle to Nalley Toyota of Roswell for a prompt scan and professional diagnosis. Certified service preserves warranty coverage and can be more economical in both immediate repair and long-term maintenance costs.
