service CHRYSLER VOYAGER 1996 Service Manual

The speed sensor generates 8 pulses per sensor
revolution. These signals, in conjunction with a
closed throttle signal from the throttle position sen-
sor, indicate a closed throttle deceleration to the
PCM. When the vehicle is stopped at idle, a closed
throttle signal is received by the PCM (but a speed
sensor signal is not received).
In addition to determining distance and vehicle
speed, the output from the sensor is used to control
speed control operation.
SPEED CONTROLÐPCM INPUTS
The speed control system provides five separate
inputs to the PCM; On/Off, Set, Resume/Accel, Cancel,
and Decel.. The On/Off input informs the PCM that
the speed control system has been activated. The Set
input informs the PCM that a fixed vehicle speed has
been selected. The Resume input indicates to the PCM
that the previous fixed speed is requested.
Speed control operation will start at 50 km/h±142
km/h (35±85 mph). The upper range of operation is
not restricted by vehicle speed. Inputs that affect
speed control operation are vehicle speed sensor and
throttle position sensor.
Refer to Group 8H for further speed control infor-
mation.
DIESEL PCM RELAYÐPCM INPUT
A 12 volt signal at this input indicates to the PCM
that the Diesel relay has been activated. The Diesel
relay is located in the PDC. The PDC is located next
to the battery in the engine compartment. For the
location of the relay within the PDC, refer to label on
PDC cover.
This input is used only to sense that the Diesel
relay is energized. If the PCM does not see 12 volts +
at this input when the Diesel relay should be acti-
vated, it will set a Diagnostic Trouble Code (DTC).
FIVE VOLT POWERÐPCM OUTPUT
This circuit supplies approximately 5 volts to
power the Accelerator Pedal Postion Sensor, Mass Air
Flow Sensor, and A/C Pressure Sensor.
ENGINE COOLANT GAUGEÐPCM OUTPUT
Refer to the Instrument Panel and Gauges group
for additional information.
ENGINE OIL PRESSURE GAUGEÐPCM OUTPUT
Refer to the Instrument Panel and Gauges group
for additional information.
GLOW PLUG LAMPÐPCM OUTPUT
The Glow Plug lamp (malfunction indicator lamp)
illuminates on the message center each time the igni-
tion (key) switch is turned on. It will stay on for
about two seconds as a bulb test.If the PCM receives an incorrect signal, or no sig-
nal from certain sensors or components, the lamp
BLINKS. This is a warning that the PCM has
recorded a system or sensor malfunction. It signals
an immediate need for service. There are only 5
HARD faults that can turn on this lamp to make it
blink.
SPEED CONTROLÐPCM OUTPUTS
These two circuits control the fuel quantity actua-
tor to regulate vehicle speed. Refer to Group 8H for
Speed Control information.
AIR CONDITIONING RELAYÐPCM OUTPUT
This circuit controls a ground signal for operation
of the A/C clutch relay. Also refer to Air Conditioning
(A/C) ControlsÐPCM Input for additional informa-
tion.
The A/C relay is located in the Power Distribution
Center (PDC). The PDC is located next to the battery
in the engine compartment. For the location of the
relay within the PDC, refer to label on PDC cover.
FUEL TIMING SOLENOIDÐPCM OUTPUT
The fuel timing solenoid is located on the bottom of
the fuel injection pump (Fig. 10).
This 12+ volt, pulse width modulated (duty±cycle)
output controls the amount of fuel timing (advance)
in the fuel injection pump. The higher the duty-

DESCRIPTION AND OPERATION
POWER STEERING PUMP OPERATION
Hydraulic pressure for the operation of the power
steering gear is provided by a belt driven power
steering pump (Fig. 1). The power steering pump is a
constant flow rate and displacement vane type pump.
The power steering pump used on all applications is
the Vane-Submerged remote reservoir style power
steering pump.
The remote reservoir type pump (Fig. 1) has the
pump housing and internal components combined
with the fluid housing. But it has a remote reservoir
for the power steering fluid supply.
DIAGNOSIS AND TESTING
POWER STEERING PUMP FLOW RATE AND
PRESSURE TEST
The following procedure can be used to test the
operation of the power steering system on the vehi-
cle. This test will provide the flow rate of the power
steering pump along with the maximum relief pres-
sure. This test is to be performed any time a power
steering system problem is present to determine if
the power steering pump or power steering gear is
not functioning properly. The following pressure and
flow test is performed using Pressure/Flow Tester,
Special Tool 6815 (Fig. 2).
Fig. 1 Vane Submerged Remote Reservoir Power
Fig. 2 Power Steering Pump Flow/Pressure Tester
NSSTEERING 19 - 9

POWER STEERING PUMP FLOW AND
PRESSURE TEST PROCEDURE
(1) Check power steering pump drive belt tension
and adjust as necessary.
(2) Disconnect power steering fluid pressure hose,
at power steering pump. Use a container for dripping
fluid.
(3) Connect Pressure Gauge, Special Tool from kit
6815 to both hoses using adapter fittings. Connect
spare pressure hose, to power steering pump pres-
sure hose fitting.
(4) Completely open valve on Special Tool 6815.
(5) Start engine and let idle long enough to circu-
late power steering fluid through flow/pressure test
and get air out of fluid. Then shut off engine.
(6) Check power steering fluid level, and add fluid
as necessary. Start engine again and let idle.
(7) Pressure gauge should read below 862 kPa
(125 psi), if above, inspect the hoses for restrictions
and repair as necessary. The initial pressure reading
should be in the range of 345-552 kPa (50-80 psi).
The flow meter should read between 1.3 and 1.9
GPM
CAUTION: The following test procedure involves
testing power steering pump maximum pressure
output and flow control valve operation. Do not
leave valve closed for more than 5 seconds as the
pump could be damaged.
(8) Close valve fully three times and record high-
est pressure indicated each time.All three read-
ings must be within specifications and within
345 kPa (50 psi) of each other.
NOTE: Power steering pump maximum relief pres-
sure is 9653 to 10342 kPa (1400 to 1500 psi.).
²If power steering pump pressures are within the
specifications but not within 345 kPa (50 psi) of each
other, then replace power steering pump.
²If pressures are within 345 kPa (50 psi) of each
other but below specifications, then replace power
steering pump.
CAUTION: Do not force the pump to operate
against the stops for more than 5 seconds at a time
because, pump damage will result.
(9) Open test valve. Turn steering wheel to the
extreme left and right positions until against the
stops, recording the highest indicated pressure at
each position. Compare pressure gauge readings to
power steering pump specifications. If highest output
pressures are not the same against either stop, the
steering gear is leaking internally and must be
replaced.
SERVICE PROCEDURES
POWER STEERING SYSTEM FLUID LEVEL CHECK
WARNING: FLUID LEVEL SHOULD BE CHECKED
WITH ENGINE OFF TO PREVENT INJURY FROM
MOVING PARTS. DO NOT USE AUTOMATIC TRANS-
MISSION FLUID IN THE POWER STEERING SYS-
TEM. DO NOT OVERFILL THE POWER STEERING
SYSTEM.
Wipe reservoir filler cap free of dirt. Then check
fluid level. The dipstick should indicate COLD when
fluid is at normal ambient temperature, approxi-
mately 21ÉC to 27ÉC (70ÉF to 80ÉF). In all pumps add
fluid as necessary, use onlyMopar Power Steering
Fluid, or equivalent. DO NOT USE ANY TYPE
OF AUTOMATIC TRANSMISSION FLUID.
POWER STEERING PUMP INITIAL OPERATION
CAUTION: The fluid level should be checked with
engine off to prevent injury from moving compo-
nents. Use only MoparTPower Steering Fluid. Do
not use automatic transmission fluid. Do not over-
fill.
Wipe filler cap clean, then check the fluid level.
The dipstick should indicateFULL COLDwhen the
fluid is at normal temperature of approximately 21ÉC
to 27ÉC (70ÉF to 80ÉF).
(1) Fill the pump fluid reservoir to the proper level
and let the fluid settle for at least two (2) minutes.
(2) Start the engine and let run for a few seconds.
Then turn the engine off.
(3) Add fluid if necessary. Repeat the above proce-
dure until the fluid level remains constant after run-
ning the engine.
(4) Raise the front wheels off the ground.
(5) Start the engine. Slowly turn the steering
wheel right and left, lightly contacting the wheel
stops.
(6) Add power steering fluid if necessary.
(7) Lower the vehicle and turn the steering wheel
slowly from lock to lock.
(8) Stop the engine. Check the fluid level and refill
as required.
(9) If the fluid is extremely foamy, allow the vehi-
cle to stand a few minutes and repeat the above pro-
cedure.
