Exhaust Gas Recirculation Sensor "C" Circuit

The engine computer detected a problem with the exhaust gas recirculation sensor C—either a wiring issue, bad connection, or sensor failure. This sensor monitors exhaust gases being recirculated to reduce emissions, and the engine needs it working properly to run efficiently. If ignored, your vehicle may run rough, fail emissions tests, or experience poor fuel economy.
