SENSOR-THROTTLE POSITION
DESCRIPTION
3.7/4.7/5.7L
The 3-wire Throttle Position Sensor (TPS) (2) is
mounted on the throttle body and is connected to the
throttle blade shaft.
The 5.7L V-8 engine does not use a separate TPS on
the throttle body.
8.3L - SRT-10
The TPS (1) is mounted on the passenger side of the
throttle body. The sensor connects to the throttle blade
shaft. The TPS is a variable resistor that provides the
Powertrain Control Module (PCM) with an input signal
(voltage).

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
3.7L V6
The Throttle Position Sensor (TPS) (1) is mounted to
the throttle body.
1. Remove air resonator tube at throttle body.
2. Disconnect TPS electrical connector.
3. Remove 2 TPS mounting screws.
4. Remove TPS.

4.7L V-8
The TPS (2) is located on the throttle body.
1. Remove air duct and tube at throttle body.
2. Disconnect TPS electrical connector.
3. Remove two TPS mounting bolts (screws).
4. Remove TPS from throttle body.
5.7L V-8
The 5.7L V-8 engine does not use a separate Throttle Position Sensor (TPS) on the throttle body.
8.3L - SRT-10
The TPS is attached to the throttle body.
1. Disconnect the TPS electrical connector.
2. Remove the TPS mounting screws.
3. Remove the TPS.

INSTALLATION
3.7L V-6
The Throttle Position Sensor (TPS) (1) is mounted to
the throttle body.
The throttle shaft end of throttle body slides into a
socket in TPS. The TPS must be installed so that it
can be rotated a few degrees. (If sensor will not
rotate, install sensor with throttle shaft on other side of
socket tangs). The TPS will be under slight tension
when rotated.
1. Install TPS and retaining screws.
2. Tighten screws to 7 Nꞏm (60 in. lbs.) torque.
3. Connect TPS electrical connector to TPS.
4. Manually operate throttle (by hand) to check for
any TPS binding before starting engine.
5. Install air cleaner tube to throttle body.

4.7L V-8
The throttle shaft end of throttle body (5) slides into a
socket in TPS. The TPS must be installed so that it
can be rotated a few degrees. If sensor will not rotate,
install sensor with throttle shaft on other side of socket
tangs. The TPS will be under slight tension when
rotated.
1. Install TPS and two retaining bolts.
2. Tighten bolts to 7 Nꞏm (60 in. lbs.) torque.
3. Manually operate throttle control lever by hand to
check for any binding of TPS.
4. Connect TPS electrical connector to TPS.
5. Install air duct/air box to throttle body.

8.3L - SRT-10
The TPS is attached to the throttle body.
The throttle shaft end of the throttle body slides into a
socket in the TPS. When indexed correctly, the TPS
can rotate a few degrees to line up the mounting
screw holes with the screw holes in the throttle body.
If the sensor will not rotate into place, install the sen-
sor with the throttle shaft on the other side of the
socket tangs. The TPS has slight tension when rotated
to align the mounting holes.
1. Install TPS and mounting screws.
2. Attach electrical connector to the TPS.
