ANTI-POLLUTION
Pet rol vapors re-aspiration
OPERATING PRINCIPLE
The communication of the t ank with t he
atmosphere is done through the carbon can. The petrol vapors are retained when they are
passing through the active carbon from the carbon
can. By means of a purging valve controlled by a
RCO signal issued by UCE injection, the petrol
vapors are re-aspired through piping by the intake
manifold.
The flow section of the purging valve is
variable, subject to the balance given by the
magnetic field created by supplying the purging
valve coil and the power of the spring ensuring
the valve closing.
RE-ASPIRATION CONDITIONS
The can-purging valve is controlled by pin
4 of the UCE injection, in the moment when:
-w ater tempera ture > 20 ° C;
- air temperature > 10 ° C;
- engine is running over a certain im-
posed charge; -valve potentiometer is not in the posi-
tion acceleration pedal not pressed.
By using the CLIP tester, it is possible the
reading of the RCO value (opening cyclic
ratio).
The purging valve is closed for a value
smaller than 0.7%. OPERATION CHECKING OF THE
CAN PURGING VALVE
A defective operation of the petrol vapors
re-aspiration system, may lead to an unstable
idling or even to the engine stopping. First of all, check:
-circuit conformity (see the operating
diagram)
-piping condition between the can and
the fuel tank (sealing, circuit clogging).
The (B) piping coming from the tank shall
be clogged.
Connect a manometer (-3…+3 bar) at the
(M) connection for communication with the
atmosphere and check at idling if there is
depression. Is there depression?
YES – Set conta ct off. Usi ng a
vacuum pump, apply a 500 - mbar depression
at the (A ) piping connection of t he purging
valve. The value of the red depression must
not have a variation more than 10 mbar
wi thin 10 seconds.

Diagnostic – General
This document is presenting the diagnostic for the injection computers SIRIUS 32, which have
nr.program E1 and Diag.variant 10.
In order to perform the diagnostic of this injection system, it is necessary to use the following
elem ents:
-D iagnostic Technical Note
-F unctional electric diagram of the respective vehicle
-CLIP technic al tester, 90 ways terminal (ELE 1497).
DIAGNOSTIC PE RFORMING STEPS
- CLIP tester connection to the diagnostic socket for identification of the SIRIUS 32 computer
type, of the “E1” program and the diagnostic variant “10”.
- Informati on identification in the document “Diagnostic” corresponding to the injection system.
- Reading and observing of the working instructions presented in the diagnostic documentation.
- Reading of the failures memorized by the injection computer, by means of the CLIP tester and
caus es identification by means of chapter “ Failures interpretation”
DO NOT ERASE T HE MEMORIZED FAILURES BEFORE RE ADING THEM BY MEANS OF THE CLIP TESTER
Write the memorized failures, after having previously red by means of the CLIP tester, in order
to be taken into consideration and treated, if these are to be themselves erased.
1. Treat all existent failures.
2. Memorized failures:
Perform the operations mentioned in “Recommendations” corresponding to each failure, in order
to confirm the failure.
If the failure is becoming present, then it must be treated.
3. For vehicle provided with OBD.
If the failure is memorized and the OBD indicator is on, read the failure context remarks, the
co rres po nding state at” OBD indicator lighting requesting”, in order to establish if this is the cause
for i ndicator lighting.
In such case, treat the failure as being present.
REMARK : the state “ OBD indicator lighting requesting” may be YES or NO and may be
co nsulted by selecting menu “ FUNCTIONS”, then OBD INDICATOR LIGHTING”.
Perform the conformity checking (evidencing of eventually disturbances not yet declared by the
system self-diagnostic). Validate the reparation performing (failure cause elimination).
Take benefit of the information from the failure-locating tree, in case the problem is persisting.

Before perform this checking, check the lines corresponde nce on the
electric diagram adequate to that vehic le.
Ch eck that choke sensor is in operating condition
M end the choke sensor if necessa ry.
Ch eck the continuity between ways 1 and 3 of the choke sensor.
If there is no continuity, repla ce the choke sensor.
Ch eck, under starter operation, the prese nce of the +12 volts at way 3 of t he choke sensor connector.
If there is no +12 volts, restore in function the line from way 3 of the choke sensor to pole 5 of the fuel
pump relay.
Ch eck the wiring condition and the mass presence at the fuel pump.
Ch eck the wiring insu lation and cont inuity :

M end if necessary.
If the incident is persisting, repla ce the fuel pump.

The operation of the engine fan is controlled by the UCE injection, as follows:
1. For vehicles without air conditioning –cooling engine fan cooling is starting when water temperature is over 99°C;
– cooling engine fan cooling is stopping when water temperature is lower than 96°C.
2. For the vehicles with air conditioning. -cooling engine fan cooling is starting on first step when water temperature is over 99°C;
- cooling e ngine fan c ooling is start ing on second step when water temperature is over
104°C; - cooling engine fa n cooling is switching from second step to first step, when water
temperature is lower than 101°C; -engine fan cooling is stopping when water temperature is lower than 96°C.
