Involved Region or Country North America
Condition Customers may bring their vehicle into the dealership for a rattle, tick, or knock type noise. This noise may also be accompanied by DTC P0300, P0302 or P0305 on the Active Fuel management System (AFM) cylinders.

Note: If there are any drivability concerns they should be addressed prior to the following diagnostic progression including any misfire DTC.

Note: Please take a sound file or video with sound of the noise prior to any  disassembly.

This may be needed when contacting TAC or to be sent to engineering.

This could be all the time, only under load, or intermittent depending on the severity of the noise.

You may find this noise hard to isolate to one area in the engine.

After you have recorded a sound file of the noise try to isolate the noise to a general area of the engine.

At that point following the steps in this PI in ORDER may help pinpoint the concern.

Cause This condition may be caused by spongy stationary hydraulic lash adjusters (SHLAs) (lifters) or  damaged switching roller finger followers (SRFF) or a left bank timing chain tensioner gasket not sealing. The condition could be all the time, only under load, intermittent, or when first started after a hot soak depending on the cause.
