Throttle body
The fuel supply for all petrol fueled variants is
equipped with a return-less fuel system. This
means that the fuel delivery pressure at the fuel
injectors, is monitored and controlled by the fuel
tank module. This control is achived by switching
the fuel pump on and off.
The fuel pump module for both the Ethanol E85

E85 variant is sealed. This is not the only
differance, both fuel pump modules have different
(
Fuel composition monitoring fuel level sensor resistor card values.
The quantity of Ethanol E85 in relation to the
quantity of unleaded fuel contained in the fuel tank
at any one time is not monitored at the fuel tank.
The Ethanol percentage volume can only decrease
from its maximum 85% (pure Ethanol
E85), to zero
(1 00% unleaded fuel).
The fuel charging system compensates for the
changes in fuel composition using the signal
received by the power train control module (PCM)
from the
H02s. The PCM adapts the fueling and
ignition calibrations to suit the current fuel tank
content composition.
Cold start
To overcome the problems relating to cold start
inherent with Ethanol E85 vehicles (temperatures
down to -29 degrees centigrade), a block heater
has been installed into the engine coolant system.
The block heater is located to the rear of the engine
under the exhaust manifold. The block heater is
fitted with a dedicated harness which terminates at an external plug connector fitted into the radiator
grill.
