P0576 — Cruise Control Input Circuit Low
Drive with caution — fix soon.
What P0576 means
This code means the engine computer detected a lower-than-expected voltage signal from the cruise control input circuit. It usually points to a faulty cruise control switch, damaged wiring, or a poor connection somewhere in the circuit. It's a fairly common, repairable issue that often comes down to a sensor or wiring fix rather than major work.
Common symptoms
- Check engine light is on
- Cruise control does not engage or turns off on its own
- Cruise control behaves erratically
- Inconsistent throttle response when using cruise
- Warning indicator for cruise control may appear
Common causes
- Faulty cruise control switch
- Damaged or corroded wiring in the cruise control circuit
- Loose or poor electrical connector
- Short to ground in the input circuit
- Failing cruise control or engine control module
Typical repair cost
$100 – $350
Varies by vehicle and root cause.
Frequently asked questions
Can I keep driving with a P0576 code?
Usually yes. The engine still runs normally, but your cruise control may not work or could act up, so plan to manage your speed manually until it's repaired.
How much does it cost to fix a P0576 code?
Most repairs land between $100 and $350, depending on whether it's a simple wiring or connector fix versus replacing the cruise control switch or module.
Is a P0576 code serious?
It's generally a moderate issue. It won't typically harm your engine, but a loss of cruise control and possible wiring fault are worth addressing soon.
Why is my cruise control not working with a P0576 code?
The low signal from the cruise control input circuit causes the system to disable itself for safety. Fixing the switch, wiring, or connection usually restores normal cruise function.
