On this vehicle, the Crankshaft Position Sensor is located on the side of the engine closest to the windshield, towards the bottom of the engine. Best access will be from under the vehicle, working upwards. Keep in mind, after the sensor has been replaced, there is a re-learn procedure that will need to be done. This will require the use of a scan-tool that can interact with the on-board computer. I've wrapped up the sensor location and replacement procedure into a PDF file.

thanks that's help alot. also if you know, buick mec said there is special relearn procedure for this part. can you or if you know how this procedure works. thanks again
Expert:  Ron Z. replied 1 year ago.

Correct- As stated above, after the sensor has been replaced, there is a re-learn procedure that will need to be done. This will require the use of a scan-tool that can interact with the on-board computer. If the re-learn is not done, engine performance issue can occur.

do i take it in or how can i do it if possibal.
Expert:  Ron Z. replied 1 year ago.

If you do not have access to a scan-tool that can interact with the on-board computer, then it cannot be done. There is no procedure to accomplish the re-learn without the scan-tool. You will need to find a shop that has the correct scan-tool.
