Now, if after the test the P0034 code returns, then follow this test procedure:

• You will need to perform a pressure test on the intakes system between the turbocharger/supercharger and intake throttle valve. This will help you to check if the pressure is low or high against the manufacturer’s specifications.
• Now if the pressure is low, you will need to check for cracks or damage in the intake hoses, intercooler, pipes and clamps. If you find them to be in best condition then check the bypass valve to determine if it is open (slightly or completely) allowing boost pressure to escape.
• In case you find that the pressure is in the normal range, then pressure sensor is faulty and needs to be replaced.
