Service Vehicle Soon
I know that the information is on this site, but my search attempts have not been fruitful.
I've been getting the "Service Vehicle Soon" message for a good while now on my 98. When I had it in the shop for some other work they told me that the problem was with the Steering Position Sensor. I believe that could be the problem because I have had the steering column off before (don't remember why...when I replaced the rack maybe?) so my guess is that when I put it back together I got it close enough that it didn't report this error...until now.
Anyway, I'm looking for instructions on how to adjust or maybe removal and replacement procedures for the Steering Positon Sensor. Can anybody point me in the right direction?

Steering Wheel Position Sensor Centering
Removal Procedure
Important
Identify the type of steering wheel position sensor from the illustrations below BEFORE removing the sensor from the steering column. Once you have identified the steering wheel position sensor, follow the instructions listed in the removal procedure.
Verify the type of steering wheel position sensor.
From the technicians point of view, the FRONT of the sensor (1) connector will be on the right.
Important
If reusing the existing sensor, you do not have to align the sensor before removal. Centering is not required when it is time to reinstall.
Remove the connector from the sensor.
Remove the sensor (1) from the adapter and bearing assembly.
To install the sensor, proceed to step 1 in the installation section.
From the technicians point of view, the FRONT of the sensor will have:
foam ring (2)
pin hole (1) for centering pin (note location of pin hole)
flush rotor flange cuff (4)
Important
If reusing the existing sensor, you must make an alignment mark on the rotor flange cuff (3) before removing the sensor. Failure to do so will cause misalignment when installing the sensor. A new sensor will be required if misaligned.
Make an alignment mark on the flush rotor flange cuff (3).
Remove the connector from the sensor.
Remove the sensor from the adapter and bearing assembly.
To install the sensor, proceed to step 5 in the installation section.
From the technicians point of view, the FRONT of the sensor will have:
raised rotor flange cuff (3)
alignment mark (2) on rotor flange cuff (3) for installation
pin hole (1) for centering pin (note location of pin hole)
Remove the connector from the sensor.
Remove the sensor from the adapter and bearing assembly.
To install the sensor, proceed to step 9 in the installation section.
From the technicians point of view, the FRONT of the sensor will have:
raised rotor flange cuff (3)
alignment mark (2) on rotor flange cuff (3) for installation
pin hole (1) for centering pin (note location of pin hole)
sensor clip in FRONT of the sensor
Remove the connector from the sensor.
Remove the sensor clip from the sensor.
Remove the sensor from the adapter and bearing assembly.
To install the sensor, proceed to step 13 in the installation section.
From the technicians point of view, the FRONT of the sensor will have:
flush rotor flange cuff (3)
pin hole (1) for centering pin (note location of pin hole)
alignment mark (2) on flush rotor flange cuff (3) for installation
Remove the connector from the sensor.
Remove the sensor from the adapter and bearing assembly.
To install the sensor, proceed to step 17 in the installation section.
From the technicians point of view, the FRONT of the sensor will have:
flush rotor flange cuff (4)
pin hole (2) for centering pin (note location of pin hole)
alignment mark (3) on flush rotor flange cuff (4) for installation
foam ring (1)
Remove the connector from the sensor.
Remove the sensor from the adapter and bearing assembly.
To install the sensor, proceed to step 21 in the installation section.
Installation Procedure
Important
If reusing the existing sensor, no centering of the sensor is required.
If installing a new sensor, it will come with a pin installed in the sensor. Do not remove the pin until the sensor is seated.
From the technicians point of view, the FRONT of the sensor (1) connector will be on your right. From the technicians point of view, the BACK of the sensor (2) connector will be on your left.
Looking at the FRONT of the sensor, align the sensor with the steering shaft and install into the adapter and bearing assembly.
Install the connector to the sensor.
From the technicians point of view, the FRONT of the sensor will have:
foam ring (4)
pin hole (7) for centering pin (note location of pin hole)
flushed rotor flange cuff (6)

1st thing: check your codes. Turn the ignition to on but don't start the car. Hold the option button and with it held in, press the fuel button 4 time within 10 seconds. The codes will start scrolling on the digital information center or you can manually scroll through them with te options button. The codes will look something like Pxxxx C or H. An h means it is a history code and C means it is current. Post your codes on here and usually you will find someone on here who has dealt with that code.

Did this start right after you had the rack out of the car? If so you may have reconnected the steering shaft 360 degrees out of synch with where it should have been. A number of people have had this problem since they didn't know the steering wheel couldn't be turned when it wasn't attached to the rack. When the shaft is turned 1 or more turns and then reattached to the rack the sensor indicates the steering is at some angle other than where the wheels are actually pointed. After a certain drive time the sensor readings will trigger the Service Vehicle Soon message.
Your problem may be fixed by just disconnecting the shaft from the rack and properly re-attaching it after turning it to the proper orientation. The car isn't a 60 Chevy.
