Yes,either above the A/C compressor or the altrnator(front of engine)
First make sure it's actually a 88 and not a 87. On a 87 it has two sensors on the bellhousing, the one on the engine is diagnotic only. On a 88 it has a sensor either above the A/C compressor or the alternator.
The Crankshaft sensor is located behind the Harmonic Balancer on the front-passenger side
The location of the crankshaft position sensor depends on which engine the car has. If it is the 2.5L 4 cylinder engine the crankshaft position sensor is behind the ignition module. If it is the 2.8L V6 engine the crankshaft position sensor is on the side of the engine nearest the firewall and just above the pan rail in about the center of the block.
Looking at the engine, all the way to the back of the block, on the left side. Right behind the air filter. It should be a black cap. That's where it is on my 88' 535i
You have to remove the Vibration Damper first, then you will have clear access to the Crank sensor. Make sure when you reinstall it, the wires don't get caught in the Damper assembly and you have clearance where the sensor mounts. Easy fix.
OEM BMW Batteries are always the best to reinstall into a BMW.

1997olds 88 the brake chime will not shut off where is the sensor so i can disengage it
Hard Set the parking brake, and block the rear tires. Jack up the right front chassis enought to remove the tire and wheel. Put safety jack stands under that area and lower the jack . Remove the plastic inner wheel well covers to gain access to the front of the engine. There you will see the bottom most engine pully (crankshaft dampner)on the serpentine belt system. At three o'clock you will see the crankshaft sensor and it's mounting bolts. The sensor extends into the metal fins on the back side of that pully. If the sensor is busted up you should remove the pully and check for bent fins. There is close clearance between the sensor and the fins and when you install a new one it has to be close and center between the fins - but not too close and the pully fins have to pass thru the sensor gate grooves without touching them.
