P0571 – Speed, idle or charging fault
Brake switch A circuit
Idle, speed and cruise · generic OBD-II code
You can drive it, but take it easy and get it looked at soon – waiting usually makes the repair bigger.
Check this first
Have the battery, charging and idle control checked – these codes often come with a rough idle.
What usually fixes it
In the order a good shop checks them. Typical total: $83–$1,125 at $130 an hour.
Clean the throttle body
Carbon build-up upsets idle speed.
Sensor or switch
Speed, brake and clutch switches sit in this group.
Battery or alternator
Charging faults set codes all over the vehicle.
This is the advice for this family of codes – Drive DTC doesn't have a page written for this exact code yet.
What the vehicle can tell you itself
A stored code is a headline, not the story. The vehicle also holds the conditions when it happened, how close the part is to the limit it fails at, what the fuel trims are doing, and whether the fault is still happening right now. Drive DTC reads all of it with a USB adapter and a Windows PC – and it can't change a single setting on the vehicle.
