OBD-II Code
P0260
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)
$180–$520
From this code's diagnostic notes. Varies by vehicle, diagnosis, parts, and local labor. This is not a repair quote.
P0260 indicates a fault in the pedal position switch B circuit, part of the redundant accelerator pedal sensor system used to cross-check throttle inputs against the main pedal position sensor.
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.

Cheapest first
- verify the pedal connector is fully seated and free of floor-mat fluid intrusion.
- With key on, engine off, watch the scan-tool pedal position B PID through full pedal travel; a properly functioning sensor sweeps roughly 0.5V at rest to 2.0-2.3V at wide-open throttle on most domestic applications (about half the voltage range of sensor A, which is the intentional redundancy design).
- Flat-lined, jumpy, or out-of-range readings condemn the pedal assembly.
- The expensive misdiagnosis is replacing the throttle body ($300-$600) when the fault is upstream at the pedal.
