Line Pressure Solenoid SLS, Amperage
WARNING: This page is about a different car, the 2002 Volvo C70, 2001 Volvo C70, 2000 Volvo C70, 1999 Volvo C70, and 1998 Volvo C70. However, it is still accessible from the selected car via links, so may be relevant.
The value indicates the amperage passing through the solenoid circuit. A lower amperage gives a higher reference pressure, which gives a higher line pressure. Solenoid control is directly dependent on the throttle sensor signal. The higher the signal from the throttle sensor the lower the amperage through the solenoid and therefore the higher the line pressure.
Measurement range: 0.0-1.5 A
Normal value at closed throttle: 280 mA
