2023 Toyota C-HR Check Engine Light Codes

Common codes for the 2023 Toyota C-HR include P0300 (random/multiple cylinder misfire), P0420 (catalyst system efficiency below threshold), and P0171/P0174 (lean condition). Left unaddressed, a P0300 misfire can damage pistons, rings, and the catalytic converter, leading to substantially higher repair bills; P0420 often becomes a catalyst replacement if the issue persists; and persistent P0171/P0174 can cause poor fuel economy and accelerated engine wear. At Herb Chambers Toyota of Auburn we explain these risks in plain language and provide accurate cost estimates so customers understand both immediate repair needs and long-term savings from proper maintenance. Our Auburn, MA location offers OEM parts, factory-trained technicians, and a comfortable service experience built to minimize downtime. We also offer service financing so you can repair now and pay over time. Before any work begins we review warranty implications—repairs covered under warranty must be completed at a certified dealer to maintain coverage.
