Product Description

This original 80 bar Haldex pressure sensor is designed for 2nd and 3rd generation AWD systems. It is installed in the Haldex control unit and helps monitor hydraulic oil pressure required for correct clutch operation and rear axle engagement. [web:223][web:226]

What This Sensor Does

  • Monitors hydraulic pressure inside the Haldex control unit
  • Provides pressure feedback required for proper AWD clutch control
  • Supports stable operation of the rear axle engagement system
  • Helps the Haldex ECU evaluate pressure-related system behaviour
  • Serves as a direct replacement for defective original pressure sensors in compatible applications
Important Identification Note This product is the white 80 bar sensor. It should not be confused with the black 40 bar sensor used in other Haldex applications. Always compare the original part before ordering. [web:226]

Common Fault Codes & Symptoms

Pressure sensor faults can lead to incorrect pressure feedback, unstable AWD behaviour or stored Haldex-related trouble codes. Haldex diagnostic references also note that pressure / temperature sensor faults should be checked first when relevant DTCs are present. [web:229][web:223]

  • Pressure sensor fault Incorrect or implausible pressure signal from the Haldex control unit
  • AWD malfunction Rear axle does not engage correctly
  • Pressure regulation issue Unstable hydraulic pressure control inside the coupling
  • Stored Haldex DTC Pressure-related fault recorded in the AWD module
  • Intermittent rear-wheel-drive support
  • Loss of traction assistance from the rear axle
  • Warning messages related to AWD or traction system
  • Repeated Haldex faults after pump or ECU service
Diagnostic Tip A pressure sensor fault does not always mean the sensor is the only problem. Wiring issues, ECU faults, pump problems or internal hydraulic defects can produce similar symptoms, so full diagnosis is recommended before replacement. [web:224][web:229]

Installation & Service Notes

Recommended Steps

  • Verify the exact OEM number and confirm the sensor is the white 80 bar type
  • Check whether the vehicle uses 2nd or 3rd generation Haldex system
  • Inspect the control unit and related wiring before replacing the sensor
  • Use the correct washer or sealing hardware where applicable
  • Clear stored fault codes after installation
  • Test AWD system operation after repair
Important Service Note Sensor replacement should be carried out carefully to avoid damage to the Haldex control unit or sealing surfaces. Always use the correct part version for the specific application. [web:226]

Why Pressure Sensors Matter

1. Pressure Monitoring

The sensor provides the control unit with hydraulic pressure information needed for AWD operation.

2. Clutch Control

Correct pressure feedback helps the Haldex system manage clutch engagement more accurately.

3. AWD Reliability

A functioning pressure sensor supports stable rear axle activation when extra traction is needed.

4. Fault Diagnosis

Reliable pressure data helps reduce incorrect system behaviour and supports more accurate troubleshooting.

Quality Assurance & Warranty

24-Month Warranty: This original pressure sensor is supplied with a 24-month warranty under normal operating conditions. [web:223]

Warranty Coverage Includes:

  • Manufacturing defects of the supplied pressure sensor
  • Material defects under normal use
