2011 Lexus GS 350 Check Engine Light Codes

In Hingham, MA, Herb Chambers Lexus of Hingham commonly diagnoses a few recurring codes on the 2011 Lexus GS 350: oxygen sensor codes (P0130–P0167 range), catalytic converter efficiency (P0420), and misfire codes (P0300–P0306). Left unaddressed, oxygen sensor failure reduces fuel economy and increases emissions, often leading to higher fuel costs and potential catalytic damage. A catalytic converter issue can escalate to expensive replacements and may cause drivability faults. Misfires can damage pistons and catalytic converters if ignored, producing far greater repair bills than prompt intervention. Our certified technicians use Lexus-specific diagnostics to pinpoint the exact cause and present a clear cost/benefit plan. Choosing dealership service delivers value: efficient diagnostics, OEM components, and warranty protection that independent shops can’t always match.
