Hi Trevor ,
When my TPS went bad, had a code, I wanted to know what happened to this thing. So I made a 2" x 3" piece of plywood and mounted the tps in the corner with an arm attached to it. Then I marked off equally spaced angle marks about 2' from the center of rotation. I was able to put it back in the same exact position and check readings. I also cleaned it several times and checked to see if that worked. I also checked the new sensor the same way on the board. They wear out. I think the conductive plastic is not very thick and the wear makes it thinner. Take care of that SVX, John

ok ok i get it it cannot be cleaned it will just have to be reset for now and I will look for a possible source for replacement for the rx TPS as new will break the bank. your walkthrough was superb trevor "THANK YOU " is cool to see all the help one can get for not just svxs, but also our other cars, of course subarus, thank you all for the help. it has been reset and is running better just not as good as I hoped guess I better start looking REAL hard for a tps for aa 86 rx turbo ( with 195/80/14 tires in it , for snow of course)

Hi William
I dont know much about the older gen of subaru, althought I used to own a 91 loyale stick 4WD. Is the TPS on your RX turbo same as EA18? If so, the junk yard at IL side of river has some older subarus. Dont know if you want to go that route? PM me if you like

Just for reference. The TPS is an input for both the ECU and TCU. If turned all the way foward to say 2.0v... It will basically lock the clutch packs in the tranfer assembly and cause serious binding and will also play games with your shifting patterns. This is really bad for your transmission

Quite a long time ago I posted the following without result. I now wonder if you could be the man to do some experimenting, provided that you have a faulty TPS on hand. Tip For Checking the TPS As a result of a thread involving a faulty throttle position sensor, a possible handy man method of a reliable fault finding method has come to mind, but experimentation is required. Many will have been annoyed by audio gear which has a noisy volume control. Has the penny dropped ?????!!!!! As most will be aware the TPS comprises a potentiometer, consisting off a conductive plastic insulating element around which traverses a wiping contact. Dirt on the surface can interrupt contact, as can a faulty element or inadequate pressure. It can be difficult to detect intermittent contact as the wiper is turned, due there being little time to register a measurement. The response time of a typical ohmmeter or voltmeter is inadequate. A meter with a bar graph or an oscilloscope is required. The handyman does not normally have access to this sort of gear. Hook up the TPS with a capacitor of a few mfds in series with a torch cell, and stick the output across the input of an audio amplifier. Anything will do, guitar amp, walkman, whatever. In fact even headphones without amplification may work. Turn the TPS and listen to the music ?! A nice rushing sound as the unit is turned will be good music. Nasty static will be bad news. This is simply an idea at this stage and requires experiment by a keen member who has a TPS on hand. I feel that the effort is worthwhile, Any takers ? What do you think?

the rx has a 1.8 turbo obviously it is a 1.8 however i am unsure if it is an ea18 motor how would one go about finding out is the question as a salvage yard part might be the way to go as it is cheaper more risky but cheaper I will see if I can get the dirt and oil off the sensor and get a part #

Now that is an interesting way to test for a fault. I take it as this is just a theoretical test that has not been done before. As I have never checked mine I just may do this some day, you know just to see if it (audio test) works.
