PCM Connector E-F (Blue)

POWERTRAIN CONTROL MODULE (PCM) VOLTAGE CHART
This PCM voltage chart is for use with a digital voltmeter to further aid in diagnosis. The voltages you get may vary due to low battery charge or other reasons, but they should be very close. The B+ symbol indicates a nominal system voltage of 12-14 volts.

CONDITIONS FOR TESTING
^ Engine at operating temperature (upper radiator hose hot).
^ Engine idling in "Closed Loop" (for "Engine Run" column) in park or neutral.
^ Test terminal not grounded.
^ Scan tool not installed.
^ Accessories "OFF."

NOTE: Before checking voltages, be sure PCM and engine grounds are clean and tight.

CHART LEGEND
* Less than 0.5 volts.

** If equipped.
