Component Description

WARNING: This page is about a different car, the 2005 Nissan Pathfinder. However, it is still accessible from the selected car via links, so may be relevant.

The EVAP control system pressure sensor detects pressure in the purge line. The sensor output voltage to the ECM increases as pressure increases.
