2010 Toyota Corolla Check Engine Light Codes

Common check engine light codes for a 2010 Toyota Corolla include P0130 (O2 sensor), P0420 (catalyst efficiency), and P0300 (multiple cylinder misfire). Ignoring these codes can elevate repair costs: a failing O2 sensor increases fuel consumption and emissions; untreated catalytic issues can lead to a much larger replacement bill and failed inspections; repeated misfires risk catastrophic converter damage.
