Engine Controls - Pin Voltage Charts 3.0L: Introduction

Pin voltage charts are supplied to reduce diagnostic time. Checking pin voltages at the ECU determines whether it is receiving and transmitting proper voltage signals. Check for voltage between specified pin and ground.

NOTE: Unless stated otherwise in testing procedures, perform all voltage tests using a Digital Volt-Ohmmeter (DVOM) with a minimum 10-megohm input impedance. Voltage readings may vary slightly due to battery condition or charging rate.

NOTE: Harness connector should remain plugged in during testing procedures. Harness connector illustrations are of harness side of connector viewed from rear (wire side).
