Sensor Range Charts: Introduction

Sensor operating range information is supplied so that it can be determined if a sensor is out of calibration. A sensor that is out of calibration may not set a trouble code; however, it will cause driveability problems.

NOTE: All voltage tests should be performed with a Digital Volt Ohmmeter (DVOM) with a minimum 10-megohm input impedance, unless specifically stated different in testing procedures.
