It involves turning the crankshaft with a wrench counter clockwise then until you reach 0 degrees and then go another 10 to 40 degrees then reverse the turn back to 0 degrees and stop there. The markings are on the belt pulley and the front plate of the engine slightly to the right of center. The cam position center can be inserted but align the drill hole on the drive wheel with the notch on the sensor housing first. Then insert into the hole in the head aiming to have the hold down bolt to be in the center of the sliding adjustment slot on the sensor.
Tighten down the bolt in the middle of the range and then follow the procedure for engine timing which involves warming up the engine to operating temperature, jumpering T1 to E in the diagnostic block, using a timing strobe light then turning the cam sensor housing to align the mark at 10 degrees. Tighten down the retaining bolt (12mm) then recheck the timing to make sure it hasn't drifted during the tightening. Removing the electrical wire jumper from the diagnostic block should allow the timing to rise above 10 degrees especially when reving the engine.
What about it?
On a 1990 Toyota Supra 3.0 Turbo, the crankshaft position sensor is located on the engine block, near the rear of the engine, adjacent to the flywheel. It is typically mounted on the bell housing of the transmission. To access it, you may need to remove some components, so ensure the vehicle is safely lifted and secured if you're working underneath it.
The 1990 Toyota speed sensor is located on the back of the transmission. There also is a speed sensor on the front passenger wheel.
That is usually a problem with the map sensor or air flow meter, depending on the model engine in said Supra. www.driftmotion.com

Not my instructions - but I have used them, and they are correct (can't verify strut part # though). http://gallery.sanitylapse.com/v/supra/Hatch+Strut+Install+5-29-05/DSC_2385.jpg.html
On a 1987 Toyota Supra non-turbo, the knock sensor is typically located on the engine block, near the cylinder head, usually on the side of the engine. It's positioned towards the rear of the engine, making it somewhat difficult to access. This sensor monitors engine vibrations to detect knocking or pinging, allowing the engine control unit to adjust timing accordingly.
The blowoff valve on the Toyota supra is fairly simple to install. You will need the following items.. 1. Tools 2. Toyota Supra manual and repair guide Now, read through manual until you find the spot where it says how to "install the blowoff valve". Next, and this is important. READ that part carefully. After reading the manual, decide what tools you are going to use. Personally, I have a preference for wrenches, pliers, and ladders. Use your tools (see list item 1)and begin repairs. Thanks and good luck.
the knock sensor is located on the driver side of the engine right under the intake it is about 1 in. it is connected so you will have to unplug it and then just screw it off
