DIAGNOSIS AND TESTING
I
The block heater can be connected to an external Throttle body
power supply, which will pre-heat the engine
i coolant contained within the cylinder block. The
' heated coolant will radiate heat to the fuel rail,
which will warm the contained fuel. Sufficient
warmed fuel is stored in the fuel rail to allow the
engine to start and continue running correctly, until
the engine combustion generates sufficient heat
to maintain correct operating conditions.
Fuel rail
The throttle body on Ethanol E85 vehicles is the
same as non Ethanol E85 variants. This is a fully
electronic controlled and monitored component.
The PCM adapts to the wear characteristics of the
throttle plate. If a new throttle body is installed, it
is necessary to teach the values of the new throttle
body to the PCM. If installing a new throttle body,
follow the initialization procedure.
REFER to: Throttle Body
(303-04C, Removal and
Installation).
The fuel rail on Ethanol E85 vehicles is the same
' as non Ethanol E85 variants. The fuel rail function
is to supply a reservoir of fuel at equal pressure
for all four fuel injectors.

The intake manifold for both Ethanol
E85 and
standard unleaded fueled vehicles is the same
construction.
Built into the intake manifold, are the
IMRC throttle
plates and IMT swirl plates.
Under low demand throttle conditions, the air
charge is delivered to the cylinder head intake ports
through the primary air intake chambers. The clean
flow of the air charge is disturbed by the IMT swirl
plates to assist in the mixing of the air fuel mixture
at the fuel injectors.

2. Visually inspect for obvious signs of mechanical
or electrical damage.

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.
