OPERATION
The 5.7L V-8 engine does not use a separate Throttle Position Sensor (TPS) on the throttle body.
The 3-wire TPS provides the Powertrain Control Module (PCM) with an input signal (voltage) that represents the
throttle blade position of the throttle body. The sensor is connected to the throttle blade shaft. As the position of the
throttle blade changes, the output voltage of the TPS changes.
The PCM supplies approximately 5 volts to the TPS. The TPS output voltage (input signal to the PCM) represents
the throttle blade position. The PCM receives an input signal voltage fromthe TPS. This will vary in an approximate
range of from .26 volts at minimum throttle opening (idle), to 4.49 volts atwide open throttle. Along with inputs from
other sensors, the PCM uses the TPS input to determine current engine operating conditions. In response to engine
operating conditions, the PCM will adjust fuel injector pulse width and ignition timing.
The PCM needs to identify the actions and position of the throttle blade at all times. This information is needed to
assist in performing the following calculations:
Ignition timing advance
Fuel injection pulse-width
Idle (learned value or minimum TPS)
Off-idle (0.06 volt)
Wide Open Throttle (WOT) open loop (2.608 volts above learned idle voltage)
Deceleration fuel lean out
Fuel cutoff during cranking at WOT (2.608 volts above learned idle voltage)
A/C WOT cutoff (certain automatic transmissions only)
REMOVAL

SENSOR-CAMSHAFT POSITION
DESCRIPTION
The Camshaft Position Sensor (CMP) on the 5.9L diesel engine is located below the fuel injection pump. It is bolted
to the back of the timing gear housing.
OPERATION
The diesel Camshaft Position Sensor (CMP) contains
a hall effect device. A rotating target wheel (tone-
wheel) for the CMP is located on the camshaft gear.
This hall effect device detects holes located on the
back side of the camshaft gear. As the camshaft gear
rotates, the holes pass the tip of the CMP.
When the leading edge of the hole passes the tip of
the CMP, the following occurs: The interruption of
magnetic field causes the voltage to switch high
resulting in a signal of approximately 5 volts.
When the trailing edge of the hole passes the tip of
the CMP, the following occurs: The change of the
magnetic field causes the signal voltage to switch low
to 0 volts.
The CMP (1) provides a signal to the Engine Control
Module (ECM) at all times when the engine is running.
TheECMusestheCMPinformationprimarilyon
engine start-up. Once the engine is running, the ECM
uses the CMP as a backup sensor for engine speed.
The Crankshaft Position Sensor (CKP) is the primary
engine speed indicator for the engine after the engine
is running.
REMOVAL
The Camshaft Position Sensor (CMP) on the 5.9L die-
sel engine is located (1) below the fuel injection pump.
It is bolted to the back of the timing gear housing (7).
1. Disconnect electrical connector at CMP sensor.
2. Remove sensor mounting bolt (6).
3. Carefully twist and pull the sensor from timing gear
housing.
4. Check condition of sensor O-ring.

SENSOR-CRANKSHAFT POSITION
DESCRIPTION
The Crankshaft Position Sensor (CKP) on the diesel engine is attached at thefront/leftsideoftheenginenextto
the engine harmonic balancer (crankshaft damper).
OPERATION
The Crankshaft Position Sensor (CKP) (5) is the pri-
mary engine speed indicator for the engine after the
engine is running.
The CKP contains a hall effect device. A rotating,
notched target wheel (tonewheel) for the CKP is
located behind the engine harmonic balancer (2). This
hall effect device detects notches located on the tone-
wheel. As the tonewheel rotates, the notches pass the
tip of the CKP.
When the leading edge of the tonewheel notch passes
the tip of the CKP, the following occurs: The interrup-
tion of magnetic field causes the voltage to switch
high resulting in a signal of approximately 5 volts.
When the trailing edge of the tonewheel notch passes
the tip of the CKP, the following occurs: The change of
the magnetic field causes the signal voltage to switch
lowto0volts.
The Camshaft Position Sensor (CMP) also provides a
signal to the Engine Control Module (ECM) at all times
when the engine is running. The ECM uses this CMP
information primarily on engine start-up. Once the
engine is running, the ECM uses the CMP as a
backup sensor for engine speed.

3.CHECK THE THROTTLE POSITION SENSOR OPERATION
Ignition on, engine not running.
With the scan tool, under Transmission Sensors, monitor the TPS voltage inthe following step.
Slowly open and close the throttle while checking for erratic voltage changes.
Did the TPS voltage change smooth and consistent?

Theory of Operation
The temperature sensor is used to sense the temperature of the transmission fluid. Transmission fluid temperature
can affect shift quality, torque converter operation and when or if some diagnostics are run. A failed temperature
sensor could affect the OBD diagnostics. If a problem occurs in the transmission temperature sensor circuit, trans-
mission temperature will be based on a calculated value.

NOTE: Engine and Transmission should be at normal operating temperature before performing this proce-
dure.
1. Start engine and apply parking brake.
2. Connect scan tool and select transmission.
3. Select sensors.
4. Read the transmission temperature value.
5. Compare the fluid temperature value with the chart.

FLUID/FILTER SERVICE
NOTE: Only fluids of the type labeled MoparATF+4, Automatic Transmission Fluid, should be used in the
transmission sump. A filter change should be made at the time of the transmission oil change. The magnet
(on the inside of the oil pan) should also be cleaned with a clean, dry cloth.
NOTE: If the transmission is disassembled for any reason, the fluid and filter should be changed.
1. Raise vehicle on a hoist. Place a drain container with a large opening, under transmission oil pan.
