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
TO maintain the same or similar power output to variant vehicle and the unleaded fueled vehicle are
that of the unleaded fuel vehicle, the fuel injectors
very similar, visual^ the only difference is the fuel
have been replaced with high flow fuel injectors. pump electrical connections which on the Ethanol
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.

DIAGNOSIS AND TESTING
The DTC is always a 5 digit alphanumerical
code, for example
"POI 00".
The first digit of a code (letter) identifies the
system which has set the code. Provision has
been made for a total of four systems to be
identified although only the
'PI code is required
for EOBD.
- 'B' for the body
- 'C' for the chassis
- 'P' for the powertrain
- 'U' for the network communications systems
All of the
"xOxxxW codes are standardized codes.
However, any manufacturer can use additional
codes over and above the standardized codes.
These will be labelled
"xlxxx"
The third digit of a code (numeric) identifies the
sub-system which has set the code.
- 'Pxlxx' for metering of fuel and air supply
- 'Px2xx' for metering of fuel and air supply
- 'Px3xx' for ignition system - combustion
misfires
- 'Px4xx' for auxiliary emission control
equipment
- 'Px5xx' for vehicle speed, idle setting and
other related inputs
- 'Px6xx' for trip computer and other related
outputs
- 'Px7xx' for transmission.
- 'Px8xx' for transmission.
- 'Px9xx' category to be determined
- 'PxOxx' category to be determined
When a concern occurs, the actions taken
include storage of the relevant information and
actuation of the MIL occurs in line with the
relevant legislation.
