2010 Toyota Corolla Check Engine Light Codes

Common check engine light codes for the 2010 Toyota Corolla include P0300 (random/multiple cylinder misfire), P0171 (system too lean), P0420 (catalyst system efficiency below threshold), P0455 (large EVAP leak), and P0135 (O2 sensor heater malfunction). Each code points to a different component and carries different costs when ignored: misfires can lead to engine damage and higher fuel use; EVAP leaks reduce emissions performance and can fail inspections; a bad O2 sensor left unattended can shorten catalytic converter life, which is a much more expensive repair.
