OBD-II Code
P0572
Severity
Not yet reviewed
Nobody on our side has assessed this code yet, so we are not going to guess at how serious it is.
Can you drive it
We cannot say
Treat it as unknown until a shop reads it with live data. If the check-engine light is FLASHING, stop driving as soon as it is safe to — that means an active misfire, whatever the code.
Indicative cost (USD)
$40–$220
From this code's diagnostic notes. Varies by vehicle, diagnosis, parts, and local labor. This is not a repair quote.
P0572 sets when the PCM sees the brake switch A circuit pulled or stuck low when the pedal is released, meaning the ECM thinks the brakes are being applied constantly.
How a shop works this
Work from evidence to part, not the other way round. A code names a circuit or a symptom; it does not name the part that failed.
Note every code that is set, not just this one.
Codes that appear together usually narrow the cause faster than any one of them read alone.
Read the freeze frame — the conditions the fault was recorded under.
Cold or warm, idle or load, road speed and engine speed. A fault that only appears cold is a different fault from one that only appears under load, even with the same code on the scanner.
Confirm the fault is current rather than history.
Clear the code and see whether it returns under those same conditions. A code that does not come back may have been logged during a repair, a flat battery, or a bad connection that has since been disturbed.
Then follow the diagnostic notes further down this page, in the order they are written.
They are written in the order a shop works this code, cheapest checks first. Where they name a component, inspect its wiring and connector before replacing it.
If the code comes back after a repair, the underlying fault is still there. That is the point to bring in a scanner with live data and freeze-frame, or a shop that has one.

Start cheapest-first
- with a scan tool look at the Brake Switch PID and physically work the pedal, watching for the state to toggle between On and Off; if it stays On with foot off the pedal, the switch is misadjusted or failed.
- Check the switch plunger gap against the pedal striker (most GM and Ford spec 0.020 to 0.060 inch of free travel at rest) and verify the switch is fully clipped into its bracket, since a popped-out switch is the single most common cause.
- If the plunger is intact, back-probe the switch connector and verify reference voltage before condemning wiring; an intermittent code with no driveability complaint is almost always the switch itself.
- The expensive misdiagnosis is replacing the BCM or PCM on a code that almost always traces to a $25 switch or a bent pedal bracket.

- 2007to 2014 GM full-size trucks and SUVs suffer from the integrated brake switch losing internal contact, often setting P0572 alongside cruise inop and shift-interlock complaints.
- 2003to 2007 Honda Accord and 2006 to 2011 Civic exhibit a known brake-pedal-bracket flex issue documented in Honda TSB where the plastic striker on the pedal arm wears down and no longer fully releases the switch plunger.
- 2005to 2010 Chrysler 300, Dodge Charger, and Magnum fail the dual-stage brake switch on the pedal bracket, often after a battery disconnect, and require relearn with a scan tool after replacement.
- 2008to 2013 Toyota Tundra and Sequoia set P0572 when the brake-light switch internal contacts oxidize.
