When Monitored and Set Condition:
P-1595 SPEED CONTROL SOLENOID CIRCUITS
When Monitored: Speed control on, vehicle speed > 25 mph, RPM < 5440, brake not
applied. For an automatic transmission, in drive mode. For a manual transmission, the
clutch not depressed.
Set Condition: The powertrain control module (PCM) actuates the vacuum and vent
solenoid but they do not respond.
