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 DTC, but it may cause driveability problems.
NOTE:
See appropriate SELF-DIAGNOSTICS article or SYSTEM & COMPONENT TESTING article for additional sensor testing procedures.
NOTE:
Unless stated otherwise in test procedure, perform all voltage tests using a Digital Volt-Ohmmeter (DVOM) with a minimum 10-megohm input impedance.
