INTRODUCTION
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.
SENSOR OPERATING RANGE CHARTS
NOTE: Unless stated otherwise in test procedure, perform all
voltage tests using a Digital Volt-Ohmmeter (DVOM) with a
minimum 10-megohm input impedance. For connector and
terminal identification, see L - WIRING DIAGRAMS article in
the ENGINE PERFORMANCE Section.
