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.
1. Test of pressure sensor.
- Ignition on.
- Press the VCT2000 symbol.
Hint: Correct pressure shall be 0.00 ± 0.08 MPa.
- Engine idling
- Press the VCT2000 symbol.
Hint: Correct pressure shall be 0.38 ± 0.08 MPa.
1. Test of temperature sensor.
- Ignition on.
- Press the VCT2000 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/DIAGNOSTICS/NETWORK/DEM.

Fault-tracing information
Use the following information and general checks during fault-tracing.
Note! Check that the fuses are intact. For locations, see the instruction manual, cover for fuse box, fuse ratings or similar.
1. Check, if possible, relevant functions in the vehicle using buttons/controls/test drives to determine the status of the fault.
Note! If the vehicle does not show any of the given symptoms in the diagnostic trouble code information (DTC), this may mean that the fault is intermittent or that the control module is not detecting the fault at this moment.
2. Use the diagnostic trouble code's frozen values, status identifiers and counter to determine the operating conditions when the fault was detected, the fault's current status and any degree of intermittence of the fault.
3. Check and fault-trace according to the fault causes that are specified in the diagnostic trouble code (DTC) information.
4. Use VIDA Vehicle communication. Read off the parameters, activate components and functions, carry out quick tests and checking routines for the diagnostic trouble codes to identify the fault.
5. Check relevant components according to Component specifications.
6. Check relevant signals using wiring diagram, signal specification and breakout box.
Note! More information is available in Design and function.
Remedy as necessary.
