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.
