Nissan variable valve timing

This TSB applies to all 1996-2009 Nissans with VVT (engines VQ35, QR25, QG18, GA16, VQ40, VK56, MR18 and MR20).

If you confirm that the MIL is on with P0011, P0014, P0021. P0024, P1110 and/or P1135, do not replace the variable valve timing solenoid valve or the sprockets without performing the complete diagnostics indicated in the EC section of the service manual. Note: The engine may also have camshaft sprocket rattle noise and/or other engine noise.

The first steps in the complete diagnostic are to make sure that:

-          Engine oil is at the operating level (add oil if needed).

-          Oil pressure is normal when measured with a gauge at the pressure switch port.
