Due to security reasons concerning the presence of throttle bodies the fuel pumps and injectors of cylinder bank 1-6
are supplied by relays controlled by LIE 7- 12 control unit and vice versa.
The pumps are stopped:
• If the engine speed drops under 350 rpm approx.;
• After a certain time (about 3 seconds) with the key to MAR position without starting up (timed enable);
Self-learning strategy
Self-learning only affects the optimum air percentage for the idle speed (0 to 60 seconds). The strength is kept constant with the target strength (value requested by the system under that particular operation condition).
The range of operation of the pre-catalytic oxygen sensor (linear) is 0.8 to 1.20.
If the value is below 1.00, the system is RICH; otherwise, the system is POOR.
The self-learning values of the linear oxygen sensors are always saved in the control unit during normal
operation.
