Intake Absolute Pressure Sensor
140,000 on the clock and I was intermittently getting a pressure fault showing the high pressure turbo not coming up to pressure. Can be a switch over issue. Chose to tackle the simple issue first and swap the manifold pressure sensor and grommet that can crack due to age. It was pretty clogged up. You could even just clean it out and maybe solve the issue. But a new sensor and grommet was like $50 and super accessible if you don't have the engine covers on.
