GENERAL INFORMATION

The 3.3L and 3.5L engines use a sequential multi-

port electronic fuel injection system (Fig. 1). The
powertrain control module (PCM) operates the elec-
tronic fuel injection system. The PCM provides pre-
cise air/fuel ratios and ignition timing for all driving
conditions.

The PCM regulates the air-fuel ratio, ignition coil

dwell and idle speed. The PCM also operates the
high speed and low speed cooling fans, charging sys-
tem, speed control system and various emission con-
trol devices.

Various sensors and switches provide inputs to the

PCM. The PCM converts all inputs into signals and
regulates various systems based on the inputs. The
PCM adjusts the systems it controls to meet chang-
ing operating conditions.

Fuel is injected into the intake port above the in-

take valve in precise metered amounts through elec-
trically operated injectors. The 3.5L engine use
bottom feed injectors while the 3.3L engine uses top
feed injectors. The PCM operates the injectors in a
specific sequence. The PCM maintains an air fuel ra-
tio of 14.7 parts air to 1 part fuel by constantly ad-
justing injector pulse width. Injector pulse width
refers to the amount of time an injector operates.

The PCM adjusts injector pulse width by opening

and closing the ground path to the injectors. Engine
RPM (speed) and manifold absolute pressure (air
density) are the primary inputs that determine injec-
tor pulse width.

SYSTEM DIAGNOSIS

The powertrain control module (PCM) can test

many of its own input and output circuits. If the
PCM senses a fault in a major system, the PCM
stores a diagnostic trouble code in memory.

Technicians can display stored diagnostic trouble

codes by two different methods. The first is to cycle
the ignition switch On - Off - On - Off - On within 5
seconds. Then count the number of times the mal-
function indicator lamp (check engine lamp) on the
instrument panel flashes on and off. The number of
flashes represents the trouble code. There is a slight
pause between the flashes representing the first and
second digits of the code. Longer pauses separate in-
dividual trouble codes.

The second method of reading diagnostic trouble

codes uses the DRBII scan tool. For diagnostic trou-
ble code information, refer to the On-Board Diagnos-
tics section in this group.

CHRYSLER COLLISION DETECTION (CCD) BUS

Various modules exchange information through a

communications port called the CCD Bus. The pow-
ertrain control module (PCM) transmits the Malfunc-
tion Indicator Lamp (Check Engine) On/Off signal
and engine RPM on the CCD Bus. PCM receives the
Air Conditioning select input and speed control en-
gage inputs over the CCD Bus. The PCM also re-
ceives the air conditioning evaporator temperature
signal from the CCD Bus.
