Inspection After Removal

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.
To avoid the risk of injury to eyes and skin, when using caustic solutions, solvents, acids, or alkaline materials follow the manufacturer's recommendations for use and wear appropriate eye protection and protective clothing. Some of these materials are also flammable. To avoid risk of fire or burns, never smoke or allow sparks or flames (such as pilot lights, electrical switches, or welding equipment) in the work area. Avoid spilling onto a hot exhaust manifold which can cause a fire.

Clean the exhaust gas pressure sensor tube with solvent and dry with compressed air.
Inspect the tube for signs of leakage, damaged sealing areas, or plugging with soot.
If the tube is plugged with soot, use solvent and a pipe cleaner, or similar device, to remove the soot blockages in the tube.
