Diagnostic Aids

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

A normal BARO reading of the vehicle's geographic location will help to determine if a BARO sensor is significantly off its reading.
The diagnostic does not run when purge is enabled because it can influence the EVAP leak detection pump pressure sensor reading if there is any restriction in the fresh air plumbing.
Test for a plugged 5 micron in-line vent filter between the EVAP system leak detection pump and the fuel fill neck.
This diagnostic is disabled when P0446 or P0497 is currently running.
