P0575 Cruise control input circuit
What P0575 means
The cruise control switches on the steering wheel or stalk send commands to the engine computer. P0575 means the computer detected an implausible or out-of-range signal from those inputs. Cruise control is usually disabled until the fault is fixed.
P0575 is a generic SAE J2012 code: it means the same on every make. The exact cause still depends on the car, so read the freeze-frame data before replacing parts.
