Where can I get illustration and instructions to install crankshaft position sensor?

This answer covers 1999-2005 Cadillac Deville, Eldorado & Seville.
Example Engine:
2002 Cadillac Seville STS 4.6L SFI DOHC HO 8cyl.

This engine has (2) Crankshaft Position (CKP) Sensors: the Upper sensor is CKP sensor B, and the lower sensor is CKP sensor A (this is included for the OBD-II DTC codes - P0385 references Sensor B = upper CKP sensor, whereas P0335 references the lower CKP sensor (sensor A)).

Both crankshaft position sensors are located in the front of the engine just above the oil filter adapter. To access both CKP sensors, jack up vehicle on the passenger side, remove the oil filter, and the oil filter adapter, including the Engine Oil Pressure (EOP) switch. See illustration.

The ARROW points toward Front of Car.
1. Upper Crankshaft Position Sensor (B).
2. Lower Crankshaft Position Sensor (A)
3. Engine Oil Pressure (EOP) switch
4. Engine Oil Level switch
The Oil Filter is the can-type object below the oil filter adapter, which includes the EOP switch. Recommend: remove oil filter with an oil filter socket/strap wrench, since it's close to the oil pan.

For the 3.0 Vulcan 12 valve engine, it's on the front of the engine, just up to the left of the crankshaft pulley. One illustration indicates about the 11:00 o'clock position relative to the pulley, and may be obscured by waterpump

The crankshaft position sensor is located in the lower front of the engine, near the motor mount. Pretty good video of this job at the link.

could be crank sensor or possibly the auto shutdown relay. use a test light to check for voltage at the coil. Hook the test light clip to ground and back probe the dark green/orange stripe wire at the coil connector. With the key on, the light should light. If not, swap the relay with another similar one--say the horn relay and try again. If still no voltage, interrogate the relay socket per instructions here: http://www.fixya.com/cars/r6022358-relay_check .
If there is power at the dark green wire, check the connector on the crankshaft sensor. I have pasted your wiring diagram as well as instructions for checking and replacing the cranks sensor below. Please let me know if you have questions.

Crankshaft Position Sensor TESTING On the 2.5L engine, the Crankshaft Position (CMK) sensor is located near the outer edge of the flywheel (or starter ring gear). On other models it is fitted to the right side of the engine block.
The only test you can perform without a DRBII scan tool, or equivalent, is a basic check of the sensor only.

1. Disconnect the sensor harness connector from the main wire harness connector.
2. Place an ohmmeter across terminals 1 and 2 (see the illustration). The meter reading should be open (infinite resistance). If a low resistance is read, replace the camshaft position sensor.

REMOVAL & INSTALLATION

All Except V-10 Engine

1. Remove the air cleaner assembly if necessary for access to the sensor.
2. Disconnect the pigtail harness from the sensor.
3. Remove the nut holding the sensor wire clip to the fuel rail mounting stud.
4. Remove the sensor mounting hardware, then the sensor.
5. Remove the clip from the sensor wire harness.

To install:

1. Install the sensor flush against the opening.
2. Install and tighten the bolts or nuts, as applicable.
3. Install the electrical connector.
4. Install the clip on the sensor wire harness.
5. Install the clip over the fuel rail mounting stud. Install the clip mounting nut.

CRANKSHAFT POSITION SENSOR - 2.5L
REMOVAL
Remove speed control servo from driver's side strut tower.
Remove crankshaft position sensor retaining bolt Crankshaft Position Sensor
Pull crankshaft position sensor straight up out of the transaxle housing.
(Disconnect crankshaft position sensor electrical connector from the wiring harness connector.
INSTALLATION - ADJUSTABLE
All vehicles will be equipped with an adjustable crankshaft position sensor. This can be identified by an elongated mounting hole in the sensor.

NOTE: If the removed sensor is to be reinstalled, clean off the old spacer on the sensor face. A NEW SPACER must be attached to the sensor face before installation. If the sensor is being replaced, confirm that the paper spacer is attached to the face of the new sensor Crankshaft Position Sensor and Spacer

Connect crankshaft position sensor electrical connector to the wiring harness connector.
Attach connector to heater tube bracket.
Install speed control servo. Tighten nuts to 9 N·m (80 in. lbs.) torque.

Hi!!

here are illustrations of the CKP (crankshaft position) sensor in 2.3L and 3.0L.

Note: In the bottom of the 2.3L drawing says Trottle Position (TP) Sensor, this is wrong, It should say CKP Sensor.


2.3L Engine


The Crankshaft Position (CKP) sensor is located to the left of the crankshaft pulley.

Fig. Crankshaft Position (CKP) sensor location-2.3L engine


3.0L Engine


The Crankshaft Position (CKP) sensor is located just behind the crankshaft pulley on engine block.

Fig. Crankshaft Position (CKP) sensor location-3.0L engine

The cost of the sensor is $23 bucks at AutoZone.
