INTRODUCTION
Note. This article is only to be used for Laser and Talon models. When testing sensors on other models, see appropriate G - TESTS W/ CODES article.
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.
