GENERAL DESCRIPTION
MULTIPORT FUEL SYSTEM (MFI) 13A-2
GENERAL DESCRIPTION
M2132000100172
The control functions are basically the same as those
for the 2.0-liter turbocharged engine of the previous
ECLIPSE (D32A, D33A). In addition to the improve-
ments already adopted on the 2.4-liter engine of the
ECLIPSE (D52A), the following improvements have
been made:
IMPROVEMENT/ADDITION REMARK
Clutch pedal position switch Reduces the amount of hydrocarbon (HC) discharge by making fuel
injection volume corrections during shift changes.
Charge air cooler water spray
control Improves output performance during high-load operating conditions
by spraying water on the charge air cooler, which cools the intake air
(if the AUTO mode is selected).
Fuel pump discharge volume
switching control Reduces the discharge of fuel vapors when the load on the engine is
low by decreasing the fuel pump speed, which decreases the fuel
return volume. (This function is basically the same as for the 3.0-liter
turbocharged engine of the 3000GT.)
Fuel level sensor 2 Along with the adoption of the saddle type fuel tank, a fuel level
sensor is provided in each of the main and sub chambers of the fuel
tank. The engine control module (ECM) determines individually
whether fuel level sensor 1 or fuel level sensor 2 has become stuck.
