INTRODUCTION

Note. Information for Escort also applies to ZX2, unless otherwise indicated.

Note. For sensor information on Villager, see SENSOR OPERATING RANGE CHARTS - VILLAGER. For sensor information on 7.3L diesel, see SELF-DIAGNOSTICS - EEC-V (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.

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

(3) At this temperature, there is a voltage overlap zone where it is possible to have either a cold end (low voltage) or hot end (high voltage) reading at the same temperature. Either voltage specification listed is correct.
