About how much is it to replace crankshaft sensor

My info says it is located above the starter motor. Info says to remove the starter.

The info also says you have to do a crankshaft variation relearn procedure. I can't help you with that procedure.

I have the same problem with my 2002 grand am and its the oil sensor sending unit it has a straight stream coming out. It sits right above the starter and saturates the starter with oil. It looks you could be leaking oil in many different spots. It looks like an oxygen sensor and very easy to change. If the threads are frozen from heat spray it with wd40 and let it sit for a while before loosening the sensor. Some oil will come out, I suggest draining the oil and disconnecting the battery because the starter is so close to the sensor before doing this job. I hope this helps you.

The crankshaft sensor is located on the driver side of the vehicle, above the differential housing. The bottom of the sensor sits above the drive plate.
Drivers side just above oil pan just behind differential

1. Disconnect the negative and positive battery cable.
2. Remove the battery.
3. Unlock and disconnect electrical connector from crankshaft position sensor.
4. Remove sensor mounting screw. Remove sensor

the oil pressure swicht collapse and pressure line leak out from the sensor .cheap to replace ,fill up the oil level after .

I am thinking that you mean crankshaft sensor. The sensor is located on the front of the engine block right above the starter you need to drop the starter and oil filter to remove the sensor. Joe

2002 Oldsmobile Aurora V8-4.0 Replace Crankshaft (Sensors) A and B This car has 2 sensors 1- Raise and support car. 2- Remove the oil filter adaptor. 3- Remove crankshaft sensor electrical connector. For specific CKP sensor identification. 4- Remove the crankshaft sensor retaining bolt. 5-Remove the crankshaft sensor. NOTE= Inspect the CS sensor o-ring for wear or damage, if problem is found replace it also. 6- Lube O-ring with clean engine oil. 7- Install theretaining bolt TIGHTEN to 10 N.m (89lb in) 8-Install the CS sensor electrical connecror. 9- Install oil filtor adaptor. 10- Lower car. 11- Operate engine and inspect Cs sensor for oil leaks 12Perform the CKP system variation learn procedure.

oil pan, or rear mainseal housings are common leaks on these... also if 4wd, diff runs thru oil pan..

crankshaft seal,and don't overfill oil level

2-0L-2.4L I-4 crankshaft sensor mounts to the engine block, behind the alternator, just above the oil filter. 2.5L V-6 crankshaft sensor mounts to transaxle just below the distributor.

the crankshaft pos. sensor is just above the oil filter. take out starter and oil filter and make sure buy a new oilfilter or just make sure that you dont destroy the one on the car . remove plug and then replace with new sensor. and make sure all rubber rings if any avalable are replaced as well. then reinstall starter and oil filter and start car
