- body position potentiometer ( 1)
- atmospheric pressure sensor (2)
- step-by-step engine (3);
- air temperature sensor( 4)
Disconnect the fuel supply ducts (supply and return)
Disconnect the petrol vapors re-aspiration hose from the inlet manifold.
Uncouple the body control lever and remove the valve body.
Dismount the attachment nuts and screws of the inlet manifold.
Extract the inlet manifold .

DISMOUNTIN G
Disconnect the battery.
Dismount the air filter.
Disconnect:
- pipe 1 for fuel supply;
- pipe 3 for fuel return;
- pipe 4 of the pressure controller.
REMARK:
For EURO 00 and EURO 96, the
pre ssure c ontrol ler and return pi pe are

Dismount the attachment screws ( 2) o f the
fuel ramp. Dismount the ramp. In order to dismount an injector, re trieve
the clip 5, and then extract the injector.
R EMOU NT I NG
Replace the annular gaskets from the
injectors bottom; if t he injector has been
dismounted, the gasket from the injector’s
head will be also replaced.
In order that petrol fuel supply and return

There is no need to erase the “adaptive values” memoriz ed by the injection computer.
In order to check the correct reparation of the system, the following conditions must be

REPARATION - No more electrical failures;
- All “adaptive values” to be memorized by the injection computer;
- Warm engine (minimum 75°C);
- Run at idling, all consumers being in use for 20 minutes (1 minute DF110);
- If the failure is again occurring, repeat the dia gnostic.

Perform the steps for memorizing the adaptation values by the injection
computer.
Erase the computer memory. A t warm, when idling adjustment, observe the se paramete rs :
- If one of t hese parameters is moving towards the minimal limit, there is not sufficient petrol or there
is t oo much air.
- If one of the se paramete rs is moving towards the minimal limit, there is too much petrol or there is
not sufficient air.
(See chapter “ Enriching adaptive correction) for the exact limit values)
Ensure the cleaning condition and the good operation of :
- fuel filter
