Titan Noise

This bulletin applies to 2010 Toyota Titan vehicles equipped with variable valve timing. If you confirm that the MIL is on with DTC P0011, P0014, P0021, P0024, P1110 and/or P1135 stored, the engine may also have camshaft sprocket rattle noise and/or other engine noise.

Do not automatically replace the variable valve timing solenoid valve or the sprocket(s) without performing the complete diagnostics indicated in the EC section of the service manual.

Check to see if the engine oil is at the operating level and add oil if necessary. Check that engine oil pressure is normal when measured with a gauge at the pressure switch point.
