What does it mean when the check engine light comes on in a 2014 Toyota Prius One?

• The light signals that the vehicle’s onboard diagnostics (OBD-II) has detected a fault — from minor sensor issues to engine or emissions system problems.
• Common causes include oxygen sensor faults, evaporative system leaks, misfires, or catalytic converter efficiency problems; hybrids can also log battery or inverter faults.
• Ignoring the light can reduce fuel economy, increase emissions, and lead to more costly repairs later, such as catalytic converter replacement.
• Bring your Prius to Bill Estes Toyota for a precise diagnosis by factory-trained technicians to protect warranty rights and save money over time.

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

• Check for something simple first: a loose or missing gas cap can trigger an EVAP code — tighten it and see if the light resets after a few drives.
• Look for obvious signs: unusual noises, loss of power, or dashboard warnings that indicate a more urgent issue.
• Even if it seems minor, we recommend a professional scan at Bill Estes Toyota to read stored codes and confirm the underlying cause.
• Remember: warranty-covered repairs must be performed at a certified dealership to maintain coverage and ensure correct long-term fixes.

What is the most common reason for check engine light on a 2014 Toyota Prius One?
