Computerized Engine Controls: Notes

850 non-turbo models use a Bosch LH 3.2 multiport fuel injection system with a EZ129K electronic ignition system with knock sensor, and with self-diagnostic capabilities.

Vehicle uses an Electronic Control Unit (ECU) that receives input from engine monitoring sensors. These sensors include camshaft sensor, coolant temperature sensor, oxygen sensor, knock sensor, mass airflow meter/sensor and throttle switch. ECU uses these input signals to control air/fuel mixture for emission control, fuel economy and good driveability. Ignition control is provided by a separate ignition ECU.
