Common check engine light codes for the 2010 Acura TL include P0420 (catalyst efficiency), P0300 (random/multiple misfires), P0171/P0174 (fuel trim issues), and oxygen sensor-related codes. Each code points to a specific problem: P0420 can lead to failed emissions tests and expensive catalytic replacement; P0300 can cause rough idle, poor fuel economy, and damage over time; fuel trim codes often indicate vacuum leaks or injector issues that reduce efficiency and increase wear.
