Need location of cranshaft sensor on 2004 cadillac

Located just after the catalytic converter.

Your crankshaft sensor b is bad this will automatically shut down a vehicle and not allow it to start

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.

It's listed on this drawing.

The check engine light doesn't have to come on with a bad crank sensor ,your vehicle has two , one for lower rpm an one for higher speeds . A&B
The two crankshaft sensors are located on the front bank (BANK 2) of the engine block between cylinders 4 and 6. Crankshaft position A sensor is located in the upper crankcase and crankshaft position B sensor is located in the lower crankcase. Both sensors extend into the crankcase and are sealed to the engine block with O-rings. The crankshaft position sensors are not adjustable.

The crankshaft sensor is an important sensor for regulating spark and fuel injection pulsing.

I don't know what an 'engine sensor' would be besides the crankshaft sensor, specifically.

Engine sensor is a general term.

crankshaft sensor is and the hormonic balance pulley and cam sesoor should b and the front of the motor toward the top. But to b sure u should get a book for u vehical

Its possible that the ignition control module may be faulty,or the crankshaft position sensor.I would suggest that you try to replace the crankshaft sensor first.The crankshaft sensor is located in the front of the engine near the ac compressor.The ignition control module is located on the back of the engine mounted above the rear valve cover underneath the coil packs.

Maybe this will help . although this is from a 1997 Caddy.
