-REVISED- 2011-2013 INFINITI QX56; WHINE NOISE FROM ENGINE AREA
A whine type noise is coming from the Bank 2 (B2) side of the timing chain system.
• The noise is best heard from the high pressure fuel pump area.
• The noise should increase in frequency with engine speed (RPM).
• If the noise does not increase with engine speed, the timing chain system may not be the cause.
Refer to the appropriate section of the Electronic Service Manual (ESM) for further diagnosis.
