Coolant pressure control sensor, component description

Location
The coolant pressure regulation sensor (B87) is located at the coolant expansion reservoir.

B87

Coolant pressure control sensor

G20.30-3132-01

Task

The coolant pressure regulation sensor (B87) monitors the pressure in the coolant circuit. The signals of the coolant pressure regulation sensor (B87) are directly read in by the common powertrain controller (CPC) (A3). The common powertrain controller CPC) (A3) calculates the control variables for the coolant pressure regulation solenoid valve from this (Y53).
