Cost To Replace Buick 3800 Crank Position Sensor

Hello? I have 2001 Buick LeSabre. I want to replace the crankshaft position sensor. Do you know how much does it cost in terms of labor?

Which engine do you have in your Buick?

V6 3800. It seems it has two CKP sensors, 7x and 24x. I am guessing the 24x is bad.

There is only one crank sensor. It produces two different signals. It is located behind the harmonic balancer. It has to be removed to install a new sensor. At a dealership you are looking around 2 hours of labor at what ever rate they charge. For an example, at my dealership it would cost you about $250 just in labor.

So the labor for this replacement is $125 per hour at your dealership?


Harmonic balancer = vibration balancer, is that right?

I’ve never heard it called a vibration balancer, but yes.

Thank you very much for your expert help !

Is the intake air temperature sensor located on the intake tube of a 1998 Buick Lesabre?

What engine do you have in your Buick?

3.8L Series 2.

Thank you for that information. The intake air temperature sensor on your car is part of the Mass Airflow Sensor that is bolted in right before the throttle body in the intake path. You would have to change the entire part even if you just need the intake air temp sensor.

Thanks for the info.


Can a 1993 buick lasabre run with out a thermostat and if so for how long?

Yes, you can run the engine without a thermostat, but i would not advise. it. Depending on the temperatures, this can atually cause the engine to overheat. And, when the weather turns cold, you will not have any heat in the car. It the engine is getting too hot, and this is the reason for your question, you need to get the problem fixed, not just try to remedy by taking out the thermostat.
