This part cross-references Bosch (e.g., 0265005322) for the same application.

Common Problems This Sensor Can Address

  • Brake warning lights related to vacuum or boost pressure signal faults
  • Inaccurate brake booster pressure readings
  • Hard brake pedal feel caused by sensor-related system issues
  • Intermittent electrical connection at the brake booster sensor harness
  • Driveability concerns tied to incorrect brake assist feedback

Installation Notes and Tips

Verify connector shape, terminal style, and vehicle application before installation.
