Section 34 (Engine Controls - Sensor Operating Range Charts): Introduction
WARNING: This page is about a different car, the 1997 Mercury Mountaineer. 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 will cause driveability problems.
NOTE:
Unless specified otherwise, perform all voltage tests using a Digital Volt-Ohmmeter (DVOM) with minimum 10-megohm input impedance.
