Component Specifications (5-Cylinder Turbocharged Engines 2003-)
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 component specification gives the value of the component when the connector is disconnected. Where no value is given, it is not possible to measure a relevant value at the component.
The number next to each Supply Voltage value indicates the terminal pin on the component to which the value refers.
