Code P061, Cruise Control Vent Solenoid Problem: Action

PCM disables cruise control.

1. Checks to see if fault is due to cruise control servo or circuit. Frequency should cycle between zero and a non-zero number. If DVOM stays at zero, circuit or PCM is at fault.
2. Checks for short to voltage in circuit No. 403.
3. Checks for open in circuit No. 451.
4. Checks PCM's ability to control cruise control servo. Voltage should cycle between zero and 12 volts. If voltage does not cycle, check for open in circuit No. 403.
