Engine Controls - Sensor Operating Range Charts: Introduction

NOTE: California and Federal applies to installed emission equipment, which may be verified by underhood emission decal. California emissions may be available in other states. References to California models applies to California emission vehicles.

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 testing procedure, perform all voltage tests using a Digital Volt-Ohmmeter (DVOM) with a minimum 10-megohm input impedance.
