Is the resistance between 2.48 and 5.66 ohms?
D7 CHECK SOLENOID FOR SHORT TO GROUND
Check for continuity between engine GROUND and the
EPC solenoid terminals with ohmmeter or other low
current tester (less than 200 milliamps). Connection
should show infinite resistance (no continuity).
Is there continuity?
Yes
INSTALL a new lead frame.
