If there is a fault with one of the components listed below, the computer enters "defect mode", which means
that replacement values are used to ensure engine operation.

CONDITION FOR BLEEDING THE CANISTER ( D7F
engine)
• Coolant temperature greater than+ 15 °C
•Air temperature greater than +10 °C.
• No load position not recognised (if there is a
fault in the throttle potentiometer sensor, the
condition of no load position not recognised is
replaced by an engine speed condition
R > 1500 rpm.).
It is possible to visualise the cyclical opening ratio
for the canister bleed solenoid using the
XR25
and #23. The solenoid is closed if #23 = 0.7 %
CONDITION FOR BLEEDING THE CANISTER (E7J
engine)
During richness regulation
Coolant temperature greater than 50°C.
Air temperature greater than 15°C.
No load position not recognised (if there is a fault
in the throttle potentiometer sensor, the
condition of no load position not recognised is
replaced by an engine speed condition
R > 1500 rpm.).
Outside richness regulation
•Coolant temperature greater than 50°C.
•Air temperature greater than 15°C.
•Full load position recognised (function of
engine speed and manifold pressure).
If there is a fault in the oxygen sensor, bleeding is
permitted outside of no load conditions.
It is possible to visualise the cyclical opening ratio
for the canister bleed solenoid using the
XR25
and #23. The solenoid is closed if #23 = 0.7 %
(minimum value).

ANTIPOLLUTION
Exhaust gas recirculation (EGR)
14
The EGR is controlled by the computer via an
ON/OFF solenoid valve.
The operation of the
EGR solenoid valve is de-
pendent upon the following parameters :
- the air temperature,
- the coolant temperature ,
- the altitude,
- the position of the load lever ,
- the vehicle speed ,
- the engine speed .
The EGR function is cut if :
- the air temperature < 16°C or
- the coolant temperature < 45°C or
- the engine speed/ load potentiometer value is
greater than a certain threshold .
The EGR is cut after operating at idle speed for 40
seconds (at zero vehicle speed).
Once the vehicle speed > 25 mph (40 km/h), the
EGR is operational again. It will be cut again after
40 seconds of operating at idle speed at zero ve-
hicle speed.
XR 25 bargraph 14 RH is illuminated if the EGR
function is permitted. In order to determine if the
EGR is actually controlled, use #24. if the value is
different from 0, the EGR is activated . F8Q Engine
