P0564 to P0596 and related codes: cruise control switches, servo and circuits
A cruise control signal (on, off, set, resume, coast or accelerate), a multi-function switch input, the servo, the vacuum or vent control circuit or the cruise lamp circuit has a fault, or the car was going too fast for cruise control to engage (P0574).
SeverityLowLittle risk to the car, but the fault stays until it is repaired.

Cruise control holds a set speed by working the throttle, through an electronic throttle on modern cars or a vacuum servo and cable on older ones. The engine computer reads the switches on the steering wheel or stalk and watches for anything that should cancel it, such as the brake or clutch pedal. When it finds a switch stuck, out of range or contradicting another, it switches cruise control off for the rest of the trip, because a cruise control that cannot be trusted to cancel is worse than none.
What causes P0565?
- A worn or sticky cruise control switch on the steering wheel or stalk
- A damaged clock spring in the steering wheel, which carries the switch wiring
- A brake or clutch switch fault, which the cruise control also checks
- A leaking vacuum hose or a failed servo, on older cars
- A damaged wire or connector in the steering column
What to check first for P0565
- Check whether the brake lights work, since a brake switch fault often disables cruise control
- Press each cruise control button and feel for one that sticks or has no click
- Watch the switch signals on a scan tool while pressing each button
- On older cars, inspect the vacuum hoses and the servo for leaks and damage
Can you drive with P0565?
You can drive safely, without cruise control. Do not use it until it is repaired, even if it seems to work again, and check that the brake lights come on, because the same fault can affect them.
In states with an OBD-II emissions inspection, a car with the check engine light on fails the test until the fault is fixed.
