Any 2.4L owners hear this - Sharp engine noise at start or while idling

[star_deceiver]

http://www.sandyblogs.com/tech....htmlOn the 2009-2010 Vibe with the 2.4L engine (RPO LAX), a rattle noise may be heard from the front of the engine at start-up or while idling. In some instances, DTC P0335, Crankshaft Position (CKP) Sensor Circuit, may set immediately following the noise. This concern may be caused by two distinct issues. · If the noise only occurs at start-up and is very short and sharp in duration (2-5 seconds), this may be an issue with the intake cam phaser not parking properly. · In rare cases (at idle), the engine may set DTC P0335 following the noise with no other drivability concerns. The vehicle does not stall or exhibit any other conditions normally associated with the DTC. Both of these issues can be traced to a concern with the intake cam phaser not parking properly. Once the noise is verified as the phaser, it must be replaced.http://forums.genvibe.com/zerothread?id ... /techlink/
