Question about 1994 Toyota Previa
Up to 1994 Previa's the cam sensors are located in the distributor, there is one for each cam. labeled G1 & G2 which are the center 2 of the 4 wires to the distributor, if you want to test them first.
Also, top wire is crank sensor, bottom is ground.
I believe you will have to replace the whole distributor.

WHEN YOU STAND ON THE FRONT OF THE CAR YOU ONE IS RIGHT BELOW OF THE INTAKE WHICH IS BANK 2 OR THE ONE CLOSE TO FIREWALL , BANK 1 ONE IS ON SAME SIDE NEXT TO THE RADIATOR BUT THEY BOTH ON THE CAM RIGHT SIDE OF THE ENGINE, THE EASIEST WAY TO IDENTIFY THEM IS THAT THEIR CONNECTOR IS GREEN, ONCE YOU LOCATE THEM THE CLIP NEEDS TO BE PUSHED DOWN TOWARD THE SENSOR FOR THE CONNECTOR TO BE RELEASED, ONCE YOU REMOVE THE CONNECTOR THERE WILL BE ONLY A 10MM SCREW HOLDING THE SENSOR PULL IT OUT , THE SAME SETTING THE NEW ONE PUSH IT ALL THE WAY IN , THIGHT THE 10MM SCREW, CONNECT IT BACK AND YOU'RE DONE,BUT FOR THE ONE ON THE BACK SOMETIMES MIGHT BE NECESARY FOR YOU TO TAKE THE INTAKE OFF....HOPEFULLY IS NOT YOUR CASE....
Good luck!!! and if you need the crank for hard starting on hot/warm, it is located on the botton middle section on the transmission is the only cable that goes down to a small piece of metal and it is held by a 10mm screw only to protect the sensor, you will se the sensor once you remove that small about 6-8 inches piece of metal. Then you'll be able to unescrew the 10mm screw that holds the crank position sensor. when you pull it off you'll be able to see the fly wheel inside the transmission...
you all enjoy your rides out htere!!!

SOURCE: location of cam position senor
Not a bad job to replace the cam position sensor, it took about two hours cost about $150.00 with oem parts. First remove air filter box,remove plastic spark plug cover. Jack up engine about an inch remove engine mount. Now you can access sensor through a convenient cover that mounts around engine mount bracket extending from engine block.( one ten millimeter bolt) Remove accessory drive belt for a little extra room and replace with new one while you are in there. Just between the two cam gears you will see a torx screw that aligns the switch when in installed. DO NOT REMOVE THIS Just above the torx screw is a reverse torx screw (6 millimeter) Put a shop rag in the access hole to catch the screw just in case you drop it ,( so it does not fall into timing belt cover) Put something "sticky" in the 6 millimeter socket such as gasket sealer to keep from losing screw. remove. Pull switch up from inside spark plug cover and install new one through the same. reinstall 6 millimeter bolt. Switch is self aligning. Reinstall belt, engine mount, air box. Doing this myself probably saved me about $150.00 to $200.00 dollars
