Drive with caution — fix soon.
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.
$100 – $350
Varies by vehicle and root cause.
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.
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.
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.
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.
