Sensor Range Charts
WARNING: This page is about a different car, the 1997 Infiniti I30. However, it is still accessible from the selected car via links, so may be relevant.
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.
