P2015 is set if variable swirl valve position fails to reach target position within 1~3 sec. while ECM already outputted motor driving signal(swirl valve fully open or close signal). This code is due to 1)swirl valve shaft stuck or problem of link device or 2)variable swirl valve position sensor output value stuck.

Threshold Value |
•
(Case 1) VSCA real value is higher than VSCA target value by more than 5%.
•
(Case 2) VSCA real value is lower than VSCA target value by more than 7%.
•
(Case 3) Variable swirl valve operating motor is mechanically stuck during operation
•
(Case 4) Variable swirl valve operating motor is mechanically stuck during learning ‘closing’ process. | |||
