Frequently Asked Questions

What is the most common reason for check engine light on a 2016 Toyota Highlander Hybrid?

• Common triggers include a loose or damaged gas cap, faulty oxygen sensors, EVAP leaks, or early catalytic converter issues.
• Minor issues like a loose fuel cap are inexpensive to correct and often clear the light after a few drive cycles.
• Left unaddressed, sensor problems and catalytic issues can escalate—raising fuel costs and causing more expensive repairs later.
• Bill Estes Toyota in IN offers prompt diagnostics and factory-trained technicians to identify the root cause and reduce long-term ownership costs.

What does it mean when the check engine light comes on in a 2016 Toyota Highlander Hybrid?

• The light signals that the vehicle’s onboard diagnostics detected a fault in emissions, fuel, ignition, or hybrid control systems.
• It can indicate anything from an evaporative system leak to misfires or sensor failures; the vehicle may still drive, but performance or economy can be affected.
• A steady light generally means a non-emergency issue; a flashing light often indicates active misfires or immediate risk and needs urgent attention.
• Our dealership uses Toyota-grade scan tools and factory diagnostics to accurately interpret codes and recommend cost-effective repairs covered by warranty when applicable.

How long does a check engine light service take?

• Initial diagnostics often take 30–90 minutes depending on symptoms and code complexity; technicians perform scans and targeted inspections during this window.
• Simple fixes like replacing a gas cap or oxygen sensor can sometimes be completed same day; more complex repairs may require parts ordering and a slightly longer turnaround.
• Bill Estes Toyota prioritizes efficient scheduling, same-day parts when possible, and clear timelines so you understand immediate and long-term benefits.

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

• Begin with simple checks: make sure the gas cap is tightened and inspect for obvious signs like low fluids or unusual noises.
• Note whether the light is steady or flashing—flashing usually indicates a severe issue and you should reduce load and have the vehicle inspected immediately.
• A diagnostic scan is the quickest way to identify the specific code; avoid clearing the light yourself without diagnosis, which can mask underlying issues.
