Engine Controls - Sensor Operating Range Charts 1.3L: 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 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.

NOTE: BARO sensor cannot be tested or serviced separately. If a Code 14 is set and cannot be cleared, PCM must be replaced.
