Injection system
CHARACTERISTICS
• Electronic control unit (UCE injection) with 90 pins SIEMENS.
• Sequential multi-poin t injection.
• Controlling one injector each time.
• Static ignition with a double ignition coil.
• Canister purging valve controlled in opening duty cycle.
• Idling regime correction subject to:
- climate maintenance (air conditioning);
- battery voltage.
• Maxima l regime:
- 6200 rot/min for first, second and third speed;
- 6000 rot/min for fourth and fifth speed.

Connect the 90 ways terminal box instead of the injection computer then check the insulation,
continuity and absence of the parasite resistance on line 32 of the injection computer.

On the vehicles equipped with refrigerant fluid pressure
transducers, the injection computer is recalculating the value of the
RE COMMENDATIONSPR 044 parameter: Compressor absorbed power, starting from the
values of the refrige rant fluid pressure.
In case of the paramete r PR027 deviation from normal values, the
value of the PR044 parameter might be wrong.
