RELAY - FUEL PUMP
DESCRIPTION
The 5–pin, 12–volt, fuel pump relay is located in the Power Distribution Center (PDC). Refer to the label on the PDC
cover for relay location.
OPERATION
The Powertrain Control Module (PCM) energizes the electric fuel pump through the fuel pump relay. The fuel pump
relay is energized by first applying battery voltage to it when the ignition key is turned ON, and then applying a
ground signal to the relay from the PCM.
Whenever the ignition key is turned ON, the electric fuel pump will operate. But, the PCM will shut-down the ground
circuit to the fuel pump relay in approximately 1–3 seconds unless the engine is operating or the starter motor is
engaged.
REMOVAL
The fuel pump relay is located in the Power Distribu-
tion Center (PDC) (2). Refer to label on PDC cover for
relay location.
1. Remove PDC cover.
2. Remove relay from PDC.
3. Check condition of relay terminals and PDC con-
nector terminals for damage or corrosion. Repair if
necessary before installing relay.
4. Check for pin height (pin height should be the
same for all terminals within the PDC connector).
Repair if necessary before installing relay.
INSTALLATION
The fuel pump relay is located in the Power Distribution Center (PDC). Refer to label on PDC cover for relay loca-
tion.
1. Install relay to PDC.
2. Install cover to PDC.

1. Remove air duct and air resonator box at throttle
body.
2. Disconnect electrical connector (2) at throttle body.
3. Remove 4 throttle body mounting bolts (4).
4. Remove throttle body from intake manifold.
5. Check condition of throttle body O-ring (2).
6. If the throttle body has been changed, the following
procedure must be performed:
a. Disconnect negative battery cable from battery.
Leave cable disconnected for approximately 90
seconds.
b. Reconnect cable to battery.
c. Turn ignition switch ON, but do not crank
engine.
d. Leave ignition switch ON for a minimum of 10
seconds. This will allow PCM to learn throttle
body electrical parameters.

6. Remove cable housing at APPS bracket by pressing on release tab with a small screwdriver.To prevent cable
housing breakage, press on tab only enough to release cable from APPS bracket.
INSTALLATION

2. Push cable housing into rubber grommet and through opening in dash panel.
3. From inside vehicle, install clip holding cable to dashpanel.
4. From inside vehicle, slide throttle cable core wire into opening in top of pedal arm.

Scan Tool to erase any APPS Diagnostic Trouble Codes (DTC’s) from PCM.

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.
