2026 Toyota GR86 Check Engine Light Codes

When your 2026 Toyota GR86 displays a check engine light, the underlying codes range from benign to urgent. Common codes we see at Stevinson Toyota East in Colorado include P0440 (evaporative emission system leak), P0133 (oxygen sensor slow response), P0420 (catalyst system efficiency), and misfire codes like P0300. Left unchecked, an EVAP leak can reduce fuel economy and trigger failed emissions tests; oxygen sensor faults lead to higher fuel use and potential catalytic damage; catalytic inefficiency risks expensive converter replacement; misfires can damage pistons and the catalytic converter. Our factory-trained technicians diagnose the exact code with OEM scanners, explain options in plain language, and recommend repairs that preserve performance and value. Choosing dealership service delivers immediate savings through accurate diagnostics and long-term savings by avoiding repeated fixes. We stock many OEM parts and offer quick turnaround—use our schedule service tool to book a convenient visit, and review current service specials to reduce your out-of-pocket cost.
