Frequently Asked Questions

What is the most common reason for check engine light on a 2008 Toyota Land Cruiser?

• Common causes include an EVAP leak (loose gas cap or hose), oxygen sensor failures, catalytic converter efficiency codes (P0420), and ignition misfires.
• Less costly items like a loose gas cap or failing O2 sensor are frequently the culprit and can impact fuel economy.
• If ignored, small issues can become costly—e.g., a bad O2 sensor or unresolved misfires can damage the catalytic converter.
• Bring your vehicle to our dealership for accurate code reading and to preserve any warranty—repairs covered under warranty must be done at a certified dealership.

What does it mean when the check engine light comes on in a 2008 Toyota Land Cruiser?

• Codes range from simple EVAP faults to misfires or sensor failures; the light is a prompt to diagnose rather than ignore.

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

• Check the gas cap—ensure it’s tightened to the click; a loose cap commonly triggers an EVAP code.
• Look for other dashboard warnings, listen for unusual noises, and note performance changes such as rough idle or loss of power.
• If the light is steady, schedule a diagnostic; if it’s flashing, stop driving and contact the dealership right away.
• For warranty protection and the best value, have diagnostics and any warranty-covered repairs performed at our certified dealership.
