DTC P26C6: Exhaust Flow Control Valve "A" Control Circuit Low; DTC P26C7: Exhaust Flow Control Valve "A" Control Circuit High; DTC P2BF9: Exhaust Flow Control Valve "B" Control Circuit Low; DTC P2BFA: Exhaust Flow Control Valve "B" Control Circuit High [05/2023 - ]: Description
The dual exhaust system is made up of the exhaust tailpipe assembly (exhaust change valve), exhaust pipe gas control actuator sub-assembly (drive motor and opening angle sensor), exhaust change valve driver and ECM. According to changes in the gas path, the system ensures both quietness when the engine speed is low and exhaust tone when the engine speed is high.
The ECM drives the drive motor of the exhaust pipe gas control actuator sub-assembly in accordance with the driving conditions to switch the exhaust change valve open or closed.
The exhaust pipe gas control actuator sub-assembly position sensor detects the valve exhaust change valve opening angle and is fed back to the ECM as an exhaust valve operation status signal.
