Guest 94LegacyL Posted June 25, 2002 Share Posted June 25, 2002 Hi, This is my first time posting but I have a question, although it might be a dumb one. Today I was cleaning my engine bay, I took off the dust cover, which is in the middle and has MPFI and etc on it. Then I realized how dirty it was. I saw the TP Sensor and it was covered with dirt. I removed the screws, and took off the sensor. I only used a clean rag and no chemicals. Then I lined up the white marks which were there before, plugged everything back in and the CEL came on. I pulled the codes and it was the TP Sensor. I tried moving it barely in every direction but to no avail. I havent tried testing the voltage because I dont have a tester but does anyone have any suggestions? Thanks Quote Link to comment Share on other sites More sharing options...
Guest Legacy777 Posted June 25, 2002 Share Posted June 25, 2002 Shouldn't have pulled that guy off without knowing exactly where to line it up. I'm assuming you have a 94 Legacy L......correct? To fix it, you will need a multimeter and a feeler gauge, one that has 0.028" and 0.035" The first gen legacies had the throttle on/off switch in the TPS. So that is the key one to get adjusted properly. I've got a pic I scanned from the FSM about how to adjust and set the sensor.....but I can't seem to find it at the moment. I may have posted it......but since the search engine still sucks I'll have to find it when i get home. Quote Link to comment Share on other sites More sharing options...
Guest Legacy777 Posted June 25, 2002 Share Posted June 25, 2002 Ok, found the scans www.main.experiencetherav...sting1.jpg www.main.experiencetherav...sting2.jpg The main thing you want to look at is on the second image, in the bottom right hand corner. It talks about setting the TPS so that the idle switch is positioned properly. Quote Link to comment Share on other sites More sharing options...
Guest 94LegacyL Posted June 25, 2002 Share Posted June 25, 2002 Josh... Thanks for the help.. I saw some testing equipment up at Lowes for a alright price. I will use that chart to test the lines and thanks again.. 94LegacyL Quote Link to comment Share on other sites More sharing options...
Guest megell Posted June 25, 2002 Share Posted June 25, 2002 Don't forget to clear the codes from the ECU when done...Megell Quote Link to comment Share on other sites More sharing options...
Guest Legacy777 Posted June 25, 2002 Share Posted June 25, 2002 All you really need to do is use this diagram Make sure you use the bottom idle stop screw like in the picture, not the top one. Quote Link to comment Share on other sites More sharing options...
Guest Scoobius Maximus Posted June 27, 2002 Share Posted June 27, 2002 I have adjusted the throttle screw. It did nothing. Why does Subaru always say do not adjust?? What happens when you do? I have, and everything is still okay! What does this mean?? OMG WTF Maximus!! Quote Link to comment Share on other sites More sharing options...
Guest Legacy777 Posted June 27, 2002 Share Posted June 27, 2002 what have you adjusted? There are two throttle stop screws. One "can" be adjusted, that's the one up top, the one at the bottom where the pic says to put the feeler gauge in.....do not touch that screw. Really you shouldn't have messed with the top one either...... You gotta adjust the TPS according to those instructions. If you can not do this, you need to take it to someone that can.
