Faulty Signal

Faulty signal

Checking the component
- Check the boost pressure sensor connector. Check for contact resistance and oxidation.
Read of the boost pressure and the atmospheric pressure with the ignition on. Check the difference between the pressure readings. The difference must not be greater than 140 hPa.
If the difference between the pressures is greater than 140 hPa, try using a new boost pressure sensor.

Hint: Normal atmospheric pressure is approximately 1013 hPa. This value varies depending on other circumstances. The atmospheric pressure sensor is integrated in the engine control module (ECM). The atmospheric pressure sensor cannot be replaced individually.

Remedy as necessary.

Hint: After carrying out the repair, check that the fault has been remedied.








- Ignition off
- Reinstall the connectors, components etc.
- Ignition on.
Read off the boost pressure and the atmospheric pressure.
Check the difference between the pressure readings. The difference must not be greater than 140 hPa.

Information

Fault-tracing information
The fault should have been detected and remedied. As this is not the case fault-tracing has failed.
Exit fault-tracing for this diagnostic trouble code (DTC) or make another attempt.

Do you want to exit fault-tracing?

Yes - Exit Fault-Tracing

No - Attempt New Test
