Engine Controls - Pin Voltage Charts: Introduction

NOTE: Perform all voltage tests using a Digital Volt-Ohmmeter (DVOM) with a minimum 10-megohm input impedance. Carefully backprobe PCM harness connector using Backprobe Set (07SAZ-001000A ) to avoid damage. Voltage readings may vary slightly due to battery condition or charging rate.

NOTE: PCM may also be referred to as ECM.
