2010 Toyota Tundra Check Engine Light Codes

Common codes for a 2010 Toyota Tundra include P0420 (catalyst system efficiency), P0171/P0174 (fuel trim lean), P0300-P0308 (misfires), and oxygen sensor faults. Left unaddressed, a P0420 can lead to higher emissions, failed inspections, and eventual catalytic converter replacement—an expensive repair. Fuel trim or sensor faults reduce fuel economy and accelerate component wear. Misfires can damage the catalytic converter and cause drivability problems. At Stevinson Toyota West in CO we interpret these codes and provide cost-effective repair plans that deliver immediate and long-term savings by preventing escalation. Our certified techs use Toyota diagnostics, OEM parts, and clear communication so you understand both the diagnosis and the value of fixing it now versus risking larger bills later.
