Checking Pressure And Temperature Sensor

NOTE:

Reading out of oil pressure can take place first after the diagnostic trouble code (DTC) has been deleted. Therefore frozen values should be printed and saved before deleting takes place.

Test of pressure sensor.
- Ignition on.
- Press the VCT2000 (Volvo Scan Tool) symbol.
  HINT: Correct pressure shall be 0.00 +/- 0.08 MPa.
- Engine idling
- Press the VCT2000 (Volvo Scan Tool) symbol.
  HINT: Correct pressure shall be 0.38 +/- 0.08 MPa.
Test of temperature sensor.
- Ignition on.
- Press the VCT2000 (Volvo Scan Tool) symbol.
  HINT: Normal value for ambient temperature when the vehicle is cold and (+20 to +50 °C) when the vehicle is driven.

If wrong value is read out, then diagnostic trouble code shall be erased and the sensor changed. After changing sensor, repeat the test procedure again.

NOTE:

There are two types of sensors, an 80 bar and a 40 bar. Differential electronic module (DEM) has hardware number 30759701, 30785483, 30759682, 30783198, 30735844, or 30783018, an 80 bar pressure sensor shall be installed. If Differential electronic module (DEM) has another hardware number than above, a 40 bar sensor shall be installed.

HINT: For reading out of hardware number, see VIDA (Volvo Scan Tool)/DIAGNOSTICS/NETWORK/DEM.
