Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Code P067, Set/Coast Or Resume/ACCEL Switch 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 cruise control switch is in ON position, voltage is available to switches when ignition is turned on. If SET/COAST or RESUME/ACCEL switches were stuck on or shorted to power, 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 disengaged until PCM sees a low voltage on both of these signals.
