A stuck lock-pin release system for a lock-pin in a cam phaser includes a
stuck lock-pin detection module and a stuck lock-pin module that
communicates with the stuck lock-pin detection module. The stuck-lock pin
detection module periodically determines whether a lock-pin in a cam
phaser is in a stuck park condition. When the lock-pin is in the stuck
park condition, the stuck lock-pin module alternately biases the cam
phaser in a first and second direction until the lock-pin is no longer in
the stuck park condition.
