Understanding common check engine light codes for a 2010 Jeep Patriot helps Tucson drivers spot problems before they escalate. Typical codes include P0420 (catalytic converter efficiency), P0135 (oxygen sensor heater circuit), P0300 (random/multiple cylinder misfire), and P0171/P0174 (system too lean).
