Cam position sensor C5 2003

2003 - 180K miles ... finally had to remove intake !
Is it prudent to replace Cam position sensor while all is apart ??
No indication that its bad ... just thought about the miles and not wanting to take intake off again !
opinions ! ?

If you do decide to replace it use an OEM sensor or you may be pulling off the intake again !!

Thanks ... have not decided to replace or not - was looking for the wisdom of the forum !
is 180k miles pushing it for the cam sensor ...?
actually I have in the past bought non-oem parts that have lasted longer -
Thanks

When changging that seanor you MUST preform a " crank angle sensor relearn procedure " anyome with a TECHII or simillar device or tuning software such as HP Tuners or EFILIVE can do this for yoiu It may not be your issue but it is a must when changiing cam or crank sensors
