Porsche Pressure Sensor Calibration

Supported coding features by PoCOM diagnostic tool https://www.obdtester.com/pocom

Pressure Sensor Calibration

What it does

• Calibrates axial acceleration, lateral acceleration, and brake pressure sensors
• Ensures accurate measurements for ABS, PSM, and traction control systems
• Supports correct vehicle stability and braking behavior

Includes

• Calibrate axial acceleration sensor
• Calibrate lateral acceleration sensor
• Calibrate pressure sensor

When it is required

• After sensor or control unit replacement
• After suspension or brake system repairs
• When ABS/PSM warning lights or fault codes appear
• During routine diagnostics if sensor values are inconsistent

Conditions that must be met

• Vehicle stationary on level ground
• Ignition ON
• Stable battery voltage
• Diagnostic tool connected
• No active critical ABS/PSM faults

What happens during calibration

• Sensors’ zero points and reference values are stored
• Control unit adjusts stability and braking algorithms
• Sensor plausibility checks are performed

If calibration is not performed

• Incorrect ABS or PSM intervention
• Fault codes or warning lights may remain
• Reduced vehicle stability and braking performance

After calibration

• Verify sensor values in live data
• Clear any fault codes
• Perform short test drive
• Confirm correct ABS/PSM and traction control operation
