Ignition off
Check the connector on boost pressure sensor 1. Check for contact resistance and oxidation according to Contact resistance and oxidation
Reinstall the components, reconnect the connectors etc.
Ignition on
Read off the signal from the boost pressure sensor 1.
Check that the signal is correct. The reading must be approximately 1000 mbar. The value varies according to other circumstances dependent on the air pressure.

If the signal is now OK, the fault was caused by poor contact in the connector.
