These tips will save people thousands. I bet if you go to a dealership, they would have replaced the entire GSA for couple of thousand dollars and reinstalled the old sensors because it is no longer available. Your car still wouldn’t move and you have no choice to pay for the GSA to get you car back.
One time I was driving and all of a sudden car won’t lower the gears I had to turn it off and unplug the battery to make it work again. Would it be the same problem with my car to change that part ?
Leaking o-ring in the GSA is a common issue that leads to the sensor going bad. At a minimum, do a visual check of the connector to the sensor to see if it is wet with SMT/brake fluid. If you want to go further, you can do a resistance test with a volt meter. You do not have to remove the sensor to do the test. New sensor is no longer available so the price of used ones have gone up to $250. Try to confirm the issue is with the sensor before spending $$. You can also ask your question with other SMT Spyder owners on the forum called Spyderchat.com. People on this form are more knowledgeable than a Toyota dealer.
If you feel comfortable getting under the car, check to see if the position sensor is wet with SMT fluid. For a quick check, you do not have to remove the sensor, just visually see if the wire/plug to the sensor is wet. If it is wet, then your sensor is starting to get contaminated with SMT fluid. In the video, 4:47 mark shows you where the sensors are located. Another possibility is your SMT fluid level is low or dirty. To check this, you will have to remove the air box. I just posted a video on how to change the SMT fluid. You can also go to SpyderChat.com, a forum for MR2 Spyder owners. You can search or post your question. There are active members that are very familiar with SMT issues.

Toyota dealers cannot buy new GSA units anymore. They will not rebuild the GSA either. Do not take a broken SMT spyder to the dealer!
Really nice video!
Would you like to purchase replacement seals and o-rings to rebuild your GSA?
How do you eventually fix the leak?
How many miles are in your SMT Spyder?
