Diagnostic Module Pressure Sensor (S320)

The diagnostic module pressure sensor is located on left wheelwell in engine compartment. The diagnostic module pressure sensor converts pressure value to a voltage signal and sends it to the diagnostic module. Pressure changes are recognized within approximately 5 milliseconds. The diagnostic module pressure sensor measures either intake manifold pressure or if the purge-flow switchover valve is activated, pressure in the line between the charcoal canister and purge control valve is measured.
