INTRODUCTION
Note. For sensor information on Van E350 with 7.3L diesel, see TESTS W/CODES - DIESEL article.
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.

| All Models | EEC-V |
Note. Unless specified otherwise, perform all voltage tests using a Digital Volt-Ohmmeter (DVOM) with minimum 10-megohm input impedance.
