Line pressure solenoid STH amperage
WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2006 Volvo S80, 2005 Volvo S80, 2004 Volvo S80, 2003 Volvo S80, and 2002 Volvo S80. 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
