Variable exhaust camshaft solenoid valve (694), E39
| Main task |
The control solenoid valve regulates the flow of engine oil to the camshaft actuator channels for controlling the exhaust camshaft. The camshaft position can be advanced and retarded.
Variable exhaust camshaft solenoid valve (694), E39, controlled by ECM, E39 (590).
| Type |
The solenoid valve has an electrically powered actuator, supplied and controlled by the ECM, E39 (590).
| Connection |
| 688 pin no. | Signal type | Description |
| A | Supply voltage | Connected to ECM pin 40(C). |
| B | Ground | Connected to ECM pin 60(C). |
The solenoid valve is supplied with power from the ECM control module, E39 (590), pin 39(C) and grounded with pulse width modulation (PWM) on its pin 59(C).
