EVAP pressure sensor (585), E39
| Main task |
The pressure sensor is used for onboard diagnostics to detect leakage in the purge system.
| Type |
A pressure sensor, the value of which is adapted to 0 kPa for ignition providing the coolant temperature is lower than 40°C and the fuel level is below 50 litres.
| Connection |
| 585 pin no. | Signal type | Description |
| A | Ground | Connected to ECM pin 26(A). |
| B | Signal | Connected to ECM pin 9(A). |
| C | Power supply, 5 V | Connected to ECM pin 10(A). |
The pressure sensor is powered with 5 V from ECM, control module, E39 (590), pin 10(A), via connector housing H24-2 and H10-3.
It is grounded in ECM in pin 26(A), via connector housing H10-3 and H24-2 and crimp J229.
Depending on the pressure difference between the tank and atmosphere, the pressure sensor supplies a proportional voltage to ECM, pin 9(A), via connector housing H10-3 and H24-2.
