Code P067, Set/Coast Or Resume/ACCEL Input Shorted: Notes

When cruise control is on, system voltage is available at one side of normally open contact of SET/COAST and RESUME/ACCEL switches. If ignition and cruise control switches are on, voltage is available to SET/COAST and RESUME/ACCEL switches. If SET/COAST or RESUME/ACCEL switches were stuck on or their signal wires to PCM were shorted to voltage, cruise control operation would begin.

To prevent this, Code P067 will set and cruise control operation is disabled if signal voltage from SET/COAST (circuit No. 84) or RESUME/ACCEL (circuit No. 87) is high continuously for 10 minutes. Cruise control will be disabled until PCM sees a low voltage on both of these signals.
