During EGR system diagnostic check
NOTE: If the wiring or connector is disconnected from the solenoid, the EGR valve will operate at all times, (adversely affecting engine idle and
performance).
CIRCUIT OPERATION
Circuit F87 supplies battery voltage to the EGR solenoid. The Powertrain Control Module (PCM) switches the ground path for the solenoid ON
and OFF on circuit K35. Circuit K35 connects to cavity 40 of the PCM.
In the START or RUN position, the ignition switch connects circuit Al from fuse 5 in the Power Distribution Center (PDC) to circuit A21. Circuit
A21 feeds circuit F87 through the 9 amp positive temperature coefficient (PTC No.1) in the junction block.
Helpful Information
Circuit F87 splices to feed Torque Converter Clutch (TCC) solenoid, EVAP/Purge solenoid, PCM, and the coil side of the fuel pump relay.
