Section 1 (Engine Controls - Sensor Operating Range Charts): Introduction: Notes
WARNING: This page is about a different car, the 2002 Volvo V40 and 2001 Volvo V40. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Perform all voltage tests using a Digital Volt-Ohmmeter (DVOM) with a minimum 10-megohm input impedance unless otherwise instructed in test procedure.
Sensor operating range information can help determine if a sensor is out of calibration. An out-of-calibration sensor may not set a trouble code, but it may cause driveability problems.
