DPB_a012_PtsNonZeroStage2

Power braking assist reduced

What does the DPB_a012_PtsNonZeroStage2 alert mean?

Pedal travel sensor reports a nonzero value during second stage.

What you'll see in your Tesla

  • Power braking assist reduced
  • Braking may require increased effort

What triggers it

The input rod sensor signal shows a positive value that is larger than the specified offset of the sensor during driving situations. This might be due to a sensor condition, mechanical issue in the pedal assembly, or the driver pressing the pedal. The monitoring counts the time in which the input rod sensor signal is higher than a threshold and the acceleration pedal is applied simultaneously while the vehicle is driving. The input rod threshold is higher than the specified sensor offset for reasons of robustness.

When it clears

A Good Check is performed if the input rod signal is smaller than the specified offset of the sensor

Potential impact

System will request Hydraulic Boost Compensation when driver pressed the brake pedal.

Affected models

Model Y 2025+
