Frequently Asked Questions
Can a brake light switch cause P0565?
A faulty brake light switch can prevent cruise control from engaging because the system requires confirmation that the brakes are not applied. However, this would typically set a brake switch code rather than P0565.
Is cruise control repair expensive?
Most cruise control repairs are moderate in cost. A switch replacement is $50 to $200. A clockspring replacement is $200 to $500 including labor. The most expensive scenario is an ECM-related issue.
Can I still drive without cruise control?
Yes. P0565 only affects cruise control functionality. The vehicle drives normally in all other respects. Cruise control is a convenience feature and its absence does not affect safety or engine operation.
