For a 2003 Toyota Highlander, common code circuit malfunctions can include issues related to the engine control module (ECM), such as P0300 (random/multiple cylinder misfire detected) or P0420 (catalytic converter efficiency below threshold). These codes can indicate problems with ignition components, fuel delivery, or exhaust systems. Diagnosing the specific malfunction typically requires using an OBD-II scanner to read the codes and further inspection of the related systems. Always consult a professional mechanic for accurate diagnostics and repairs.
