Output Signals - Fuel Injection

The MPFI and SPFI control units process information from the input sensors and sends appropriate voltage control signals to the following engine controls:

• Air Control Valve (Emission)
• Air Regulator Control (Idle Speed)
• Auxilary Air Control Valve (1.8L MPFI - Idle Speed)
• By-Pass Air Control Valve (1.8L SPFI & 2.7L - Idle Speed)
• Canister Purge Control (CPC) Solenoid (Emission)
• "CHECK ENGINE" Light (Self-Diagnostics)
• Detonation (Knock) Sensor (1.8L Turbo & 2.7L - Timing)
• EGR Control Solenoid Valve (Emission)
• Exhaust Gas Sensor Heater Control (California - Emission)
• Fuel Injector(s) (Fuel Control)
• Fuel Pump Control (Fuel Delivery)
• Power Transistor & Ignition Coil (Ignition)
• Pressure Regulator Control Solenoid Valve (Fuel Delivery)
• Self-Diagnostics (Self-Diagnostics)
