Engine Controls - Sensor Operating Range Charts 4.0L: 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 will cause driveability problems. To determine correct engine control system, see SYSTEM APPLICATION table.
