id0140u1004600
Purpose/Function
• Detects the vacuum in the power brake unit to assure brake performance while the engine is stopped by the i-stop control.
• Detects the vacuum in the power brake unit and sends it to the PCM as a power brake unit vacuum pressure signal.
Construction
• Installed to the power brake unit.
• The power brake unit vacuum sensor has adopted a piezoelectric element to the detection area for detection of the vacuum in the power brake unit.
Operation
• The signal, which changes according to the vacuum in the power brake unit, is send to the PCM.
