WARNING: This page is about a different variant/trim than selected.

A skewed or stuck exhaust differential pressure sensor will cause DTC P2453 to set.
The flexible part of the exhaust differential pressure lines are made of a high temperature hose that is protected by a braided covering. If the hoses are twisted or bent, they will not return to their normal size and shape. If the hoses are restricted, it may cause DTC P2453 to set.
