Engine Controls - Sensor Operating Range Charts: 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.

NOTE: Unless stated otherwise in test procedure, perform all voltage tests using a Digital Volt-Ohmmeter (DVOM) with a minimum 10-megohm input impedance.
NOTE: Crankshaft Position (CKP) sensor and Camshaft Position (CMP) sensor resistance information is not available from manufacturer.
NOTE: For circuit identification, see WIRING DIAGRAMS article. For connector views, see TERMINAL IDENTIFICATION in appropriate SELF-DIAGNOSTICS article, unless otherwise noted.
NOTE: Resistance values will vary depending on temperature. In some instances, temperature value is not given by manufacturer.
