Engine Controls - Pin Voltage Charts: Introduction

Pin voltage charts are supplied to reduce diagnostic time. Checking pin voltages at the Powertrain Control Module (PCM) determines whether it is receiving and transmitting proper voltage signals. Charts may also help determine if PCM harness is open or shorted.

NOTE: Harness connector should remain plugged in during testing procedures. Harness side of connectors are shown in PCM harness connector illustrations. See Fig 1 or Fig 2 .
