Introduction
Sensor operating range information can help determine if a sensor is out of calibration. An out-of-calibration sensor 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.
