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

• Start with a visual and simple check: ensure the gas cap is tightened—loose caps are a common cause of emissions codes.
• Next, note whether the light is steady or flashing; flashing indicates a more urgent condition like a misfire.
• Schedule a diagnostic scan with Nalley Toyota Union City so our technicians can read stored trouble codes and recommend the correct repair path.
• Remember: warranty-covered repairs must be performed at a certified dealership to preserve coverage and ensure proper OEM repair procedures.

• If immediate repairs are needed, we provide time estimates up front and prioritize safety-related fixes.
• Our factory-trained technicians and direct access to OEM parts help reduce turnaround time and lower the chance of repeat visits.

What is the most common reason for check engine light on a 2022 Toyota GR86?

• The most frequent triggers are ignition misfires, oxygen sensor failures, or emissions system faults such as evap leaks—these affect performance and emissions.
• Misfires can stem from spark plugs, coils, or fuel delivery problems and should be addressed quickly to avoid catalytic converter damage.
• Our dealership uses precise diagnostics to identify root causes and recommend cost-effective, long-term solutions rather than quick resets.
