Frequently Asked Questions

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

• Check simple items first: a loose or missing gas cap can trigger the light and is an easy fix.
• Confirm recent fuel stops or unusual driving conditions; evaporation system faults often follow low-quality fuel.
• For hybrids like the 2013 Toyota Highlander Hybrid, inspect for obvious signs—fluid leaks, strange noises, or dashboard warnings—before driving far.
• If the light persists or returns after tightening the gas cap, schedule a certified diagnostic at Bill Estes Toyota for accurate OBD-II scanning.
• Remember: warranty-covered repairs must be completed at a certified dealership to preserve coverage and long-term savings.

• Most diagnostics at our service center take about 30–90 minutes, depending on test depth and any road checks required.

• More complex repairs—fuel system work, catalytic converter replacement, or hybrid-system concerns—may require parts and take one or more days.
• At Bill Estes Toyota we prioritize speed without cutting corners; factory-trained technicians and OEM parts help reduce repeat visits and long-term costs.

What does it mean when the check engine light comes on in a 2013 Toyota Highlander Hybrid?

• The check engine light signals that the vehicle’s computer has detected a fault in emissions, engine, or hybrid systems that needs attention.
• Issues can range from minor (evap leaks, sensor faults) to serious (misfires, catalytic converter or hybrid battery problems).
• For hybrids, certain warnings may relate to battery or energy-management systems—these require technicians with hybrid training and OEM tools.
• Bringing your Highlander Hybrid to Bill Estes Toyota ensures accurate diagnosis, factory parts, and warranty-friendly repairs that save money now and later.
• If the light is on, don’t ignore it—early intervention prevents larger repairs and protects resale value.

What is the most common reason for check engine light on a 2013 Toyota Highlander Hybrid?

• Common triggers include oxygen or O2 sensor failures, evaporative system leaks (often a loose gas cap), and intermittent misfires.
• O2 sensors and evap leaks are frequent causes because they affect emissions and are monitored continuously by the vehicle’s computer.
• Left unaddressed, sensor faults can reduce fuel economy and cause catalytic converter damage—raising repair costs significantly.
• Our certified technicians identify root causes quickly, minimizing downtime. Using OEM parts and correct procedures reduces long-term repair expense.
• Warranty-covered items must be serviced at an authorized dealership to preserve coverage and maximize savings.
