Pressure sensor
| Pressure sensor |
The pressure sensor is located on the right side of the condenser, seen in the travel direction of the car. The pressure sensor is a so-called linear pressure sensor and provides, together with the DICE programming, the following functions:
| 1. |
It allows the compressor to operate at temperatures down to ±0°C. The pressure in the system at this temperature is approximately 2 bar.
|
|
| 2. |
It starts the engine cooling fan (stage 1) at a pressure of 9 bar. When the pressure drops to approximately 7 bar, the fan cuts out again.
|
|
| 3. |
For cars equipped with a two-stage cooling fan, the second stage starts when the pressure in the A/C system exceeds approximately 18 bar. When the pressure drops to approximately 14 bar, stage 2 cuts out again. The cooling fan continues to operate at stage 1.
|
|
| 4. |
It opens the electric circuit to the compressor if the pressure exceeds 27 bar. When the pressure has dropped to approximately 24 bar, the compressor cuts in again.
|
|
| Diagnosis |
If diagnostic trouble code B2360 is generated in DICE for the pressure sensor, the A/C compressor will not cut out/cut in.
