12 Nꞏm (105 in. lbs.).
5. Attach electrical connectors to fuel injectors.

2. Disconnect electrical connector at top of fuel pump module. To disconnect electrical connector: Push upward on
red colored tab to unlock. Push on black colored tab while removing connector.
3. Disconnect necessary emission vent lines from leak pump and EVAP canister (4) and/or (5).
4. Disconnect fuel supply line (2) from fuel pump module (1).
5. Disconnect necessary emission vent lines from check valves (3) and/or (7) at top of tank.

FILTER - INLET
REMOVAL
The fuel pump inlet filter (strainer) is located on the
bottom of the fuel pump module (1). The fuel pump
module is located inside of fuel tank.
1. Remove fuel tank. Refer to Fuel Tank Removal/In-
stallation.
2. Remove fuel pump module. Refer to Fuel Pump
Module Removal/Installation.
3. Remove filter by carefully prying 2 lock tabs (2) at
bottom of module with 2 screwdrivers. Filter is
snapped to module.
4. Clean bottom of pump module.
INSTALLATION
The fuel pump inlet filter (strainer) is located on the bottom of the fuel pump module. The fuel pump module is
located inside of fuel tank.
1. Snap new filter to bottom of module. Be sure o-ring is in correct position.
2. Install fuel pump module. Refer to Fuel Pump Module Removal/Installation.

SENSOR-CRANKSHAFT POSITION
DESCRIPTION
3.7L V-6
The Crankshaft Position (CKP) (2) sensor is mounted
into the right rear side of the cylinder block. It is posi-
tioned and bolted into a machined hole.
4.7L V-8
The Crankshaft Position (CKP) (1) sensor is mounted
into the right rear side of the cylinder block. It is posi-
tioned and bolted into a machined hole.

5.7L V-8
The Crankshaft Position (CKP) (4) sensor is mounted
into the right rear side of the cylinder block. It is posi-
tioned and bolted into a machined hole.
OPERATION
3.7L V-6
Engine speed and crankshaft position are provided
through the CKP (Crankshaft Position) sensor. The
sensor generates pulses that are the input sent to the
Powertrain Control Module (PCM). The PCM interprets
the sensor input to determine the crankshaft position.
The PCM then uses this position, along with other
inputs, to determine injector sequence and ignition
timing.
The sensor is a hall effect device combined with an
internal magnet. It is also sensitive to steel within a
certain distance from it.
A tonewheel (targetwheel) (1) is bolted to the engine
crankshaft. This tonewheel has sets of notches (2) at
its outer edge.
The notches cause a pulse to be generated when they
pass under the sensor. The pulses are the input to the
PCM.

REMOVAL
3.7L V-6
The Crankshaft Position (CKP) sensor is mounted into
the right rear side of the cylinder block. It is positioned
and bolted into a machined hole.
1. Raise vehicle.
2. Disconnect sensor electrical connector.
3. Remove sensor mounting bolt (1).
4. Carefully twist sensor (2) from cylinder block.
5. Check condition of sensor O-ring (3).
4.7L V-8
The Crankshaft Position (CKP) sensor is located at
the right-rear side of the engine cylinder block. It is
positioned and bolted into a machined hole in the
engine block.
1. Raise vehicle.
2. Disconnect CKP electrical connector at sensor.
3. Remove CKP mounting bolt (2).
4. Carefully twist sensor (1) from cylinder block.
