Location

Pressure sensor, EVAP (585)

Main task

The pressure sensor is used for onboard diagnostics to detect leakage in the purge system.

Type




Connection

Pin No. Signal type Description
C Power supply, 5 V Connected to ECM pin 43(A).
A Ground Connected to ECM pin 32(A).
C Signal Connected to ECM pin 11(A).




Based on the pressure difference between the tank and atmosphere, the pressure sensor yields a proportional voltage to control module pin 11(A). The pressure sensor value is adapted to 0 kPa when the ignition is switched on provided coolant temperature is less than 40°C and fuel level is less than 50 litres.
