Service
Perform intake system pressure test to detect leaks in the intake system as follows:
-
Separate intake hose from Mass Air Flow Sensor (MAF) assembly.
-
Remove crankcase ventilation hose from PCV valve and close off crankcase side of valve with plug (white arrow), hose, and clamps (supplied
with Turbocharger Tester, see Required Parts and Tools).
Tip: This will disconnect the engine crankcase from the intake system.
-
Insert Air Pressure Adaptor (black arrow), see Required Parts and Tools into intake hose between MAF sensor and intake system (clamp using
existing hose clamp).
Tip: Hose at throttle assembly will stay connected during the test.
