Engine Control Module (ECM)

The ECM controls all turbocharger control functions. The ECM monitors information from various sensor inputs that include the following:

• Accelerator pedal position sensor.
• Engine coolant temperature (ECT) sensor.
• Mass air flow (MAF) sensor.
• Manifold absolute pressure (MAP) sensor.
• Vehicle speed sensor (VSS).
• Transmission gear position or range information sensors.
