Frequently Asked Questions

What is the first thing to check when the check engine light comes on in a 2022 Toyota Highlander Hybrid?

• Check for obvious signs: a loose or damaged gas cap, low oil level, or visible fluid leaks—these simple issues can trigger a warning.
• Scan the vehicle with an OBD-II reader to capture trouble codes; this gives clear direction for diagnosis and keeps testing efficient.
• Inspect dashboard messages and hybrid system indicators—some codes affect both the gasoline engine and hybrid components.
• Bring the vehicle to our dealership if codes are unclear or if you’re unsure. Certified repairs under warranty must be done at a certified dealership to preserve coverage.

What does it mean when the check engine light comes on in a 2022 Toyota Highlander Hybrid?

• The light signals that the engine control module detected a fault—from minor issues like an evaporative leak to serious misfires or emissions system failures.
• On a hybrid, the warning can relate to both the internal combustion engine and hybrid components; a scan reveals the affected system.
• Ignoring the light lets problems escalate, increasing repair costs and the risk of catalytic converter or hybrid system damage.
• Our dealership often costs less than independent shops while delivering factory-trained technicians, accurate diagnostics, and warranty-compliant repairs that deliver immediate and long-term savings.

How much does a check engine light diagnostic cost for a 2022 Toyota Highlander Hybrid?

• Diagnostic fees vary, but our dealership offers transparent, competitive pricing and will outline recommended repairs before work begins.
• Simple scans may be quoted affordably; advanced diagnostics for hybrid or intermittent faults can require additional time and testing—our estimates reflect that transparency.
• Choosing Nalley Toyota Union City often saves you money versus many independent shops because accurate diagnosis prevents repeat visits and unnecessary parts replacement.
• Remember: repairs covered by warranty must be performed at a certified dealership to maintain coverage and protect long-term value.

What is the most common reason for the check engine light on a 2022 Toyota Highlander Hybrid?

• Common triggers include oxygen sensor faults, catalytic converter efficiency codes, fuel trim/lean conditions, and engine misfires—each affects emissions or drivability.
• On hybrids, issues with sensors tied to the hybrid control system or EV components can also illuminate the light.
• Prompt dealer diagnosis helps prevent collateral damage—what starts as a sensor replacement can escalate into a catalytic converter or engine repair if delayed.
• Our certified technicians use OEM parts and Toyota-specific diagnostics to resolve root causes quickly, delivering immediate savings and protecting long-term ownership costs.

How long does a check engine light service take?

• Basic code reads and a visual inspection can take 30–60 minutes; diagnostics and repairs vary depending on the fault complexity.
• Simple fixes—like tightening or replacing a gas cap or swapping an O₂ sensor—may be same-day services; complex issues, hybrid system tests, or part orders can extend timelines.
• We prioritize accurate diagnosis to avoid unnecessary work; investing time up front often reduces total downtime and long-term expense.
• Warranty repairs must be completed at a certified dealership; this ensures coverage and protects resale value while often costing less than independent shops because of fewer comebacks and correct OEM parts.
