General Description

If the throttle body gets closed suddenly during engine running, boost pressure gets higher. RCV prevent this high pressure air from moving reversely and making an impact noise with impeller of compressor by sending this high pressure air to compressor IN.

DTC Description

If the ETC throttle is closed, boost pressure has to be returned through turbo charger bypass valve. But if this bypass valve is blocked by any problem, the boost pressure makes an impact. ECU shows P2261 when it senses abnormal sticking of turbo charger bypass valve.
