Section 2 (Engine Controls - Sensor Operating Range Charts): Introduction
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 1999 Jaguar XK8, 1999 Jaguar XJR, 1999 Jaguar XJ8, 1998 Jaguar XK8, and 1998 Jaguar XJR. However, it is still accessible from the selected car via links, so may be relevant.
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.
NOTE:
Unless stated otherwise in test procedure, perform all voltage tests using a Digital Volt-Ohmmeter (DVOM) with a minimum 10-megohm input impedance.
