WARNING: This page is about a different car, the 2018 Nissan Titan XD. However, it is still accessible from the selected car via links, so may be relevant.

WARNING: When using compressed air for cleaning, to avoid the risk of personal injury from flying debris and dirt:

Do not exceed 207 kPa (2.111 kg/cm ² , 30 psi).
Wear appropriate eye protection and protective clothing including gloves.
Use soapy water to clean any oil from the crankshaft speed indicator ring and vibration damper.
Dry the crankshaft speed indicator ring and vibration damper with compressed air.

Inspect the crankshaft speed indicator ring for missing or bent teeth, cracks, or damaged surfaces.
If damage is found, the vibration damper must be replaced.
Check the alignment marks (A and B) on the inner and outer rings, if the lines are more than 1.59 mm (0.063 in) out of alignment, replace the vibration damper.
