Power Output
- Turn ignition on. Disconnect turbocharging pressure sensor vacuum hose from intake manifold. Connect voltmeter to terminals "PIM" and "E2" (pressure sensor) of ECU connector and measure output voltage under ambient atmospheric pressure.
- Attach a vacuum pump to turbocharging pressure sensor vacuum hose and apply vacuum in specified stages. See Fig 1. Measure and record voltage readings for each stage of applied vacuum. See VACUUM/VOLTAGE SPECIFICATIONS table. Replace sensor if readings are not within specifications.
