PROBLEM
Certain 311F, 312F, and 313F Excavators have experienced intermittent black exhaust smoke and low engine power accompanied by error codes related to boost pressure sensor (102-20: "Engine intake manifold pressure sensor: Data drift").
Degradation of the performance of the internal connections within the engine harness interface connector may occur with extended hours due to vibrations. This can lead to the above-mentioned issue and symptoms.
A new harness support bracket 517-0154 is an approved improved part which prevents the above failure mode by improving the installation of the harness interface connector.
