Engine Controls - Pin Voltage Charts: Introduction
Pin voltage charts for Saturn are not available from the manufacturer. This article pertains to terminal identification only.
Checking pin voltages at the electronic control unit determines whether the control unit is receiving and transmitting proper voltage signals. See Figure and Figure for ECM connector terminal identification.
NOTE:
Unless stated otherwise in testing procedures, all voltage tests should be performed with a Digital Volt-Ohmmeter (DVOM) with a minimum 10-megohm input impedance.
