J - PIN VOLT AGE CHART S
1991 ENGINE PERFORMANCE Ford/Mercury Pin Voltage Charts
INTRODUCTION
Pin voltage charts are supplied to reduce diagnostic time. Checking pin voltages at the Electronic Control Assembly (ECA) determin es
whether it is receiving and transmitting proper voltage signals. Charts may also help determine if ECA wiring harness is shorted or opened.

NOTE:Unless stated otherwise in testing procedures, perform all voltage tests using a Digital Volt-Ohm m eter
(DVOM) with a m inim um 10-m egohm input im pedance. Voltage readings m ay vary slightly due to
battery condition or charging rate.
NOTE:For additional pin voltage inform ation, see appropriate trouble code inform ation in G - T EST S W/
CODES article in the ENGINE PERFORMANCE Section.
