perryg114 Posted January 19, 2010 Share Posted January 19, 2010 Does anyone have the install proceedure for the throttle position sensor? I would assume those slotted mounting holes are slotted for a reason? If I had to quess I would say that you adjust so the sensor is at the beggining of travel as soon as you open the throttle plate in the throttle body. The car is a 96 Legacy wagon (not the outback) with the 2.2 liter AWD automatic. Perry Link to comment Share on other sites More sharing options...
Bdubs Posted January 19, 2010 Share Posted January 19, 2010 There should be alignment marks on the slotted holes put on at the factory. If not, you may be able to see where screws were fastened before, and you'd fasten it exactly at the marks. Link to comment Share on other sites More sharing options...
perryg114 Posted January 19, 2010 Author Share Posted January 19, 2010 Well I am installing a new sensor. I am getting an error code on the original sensor. Perry Link to comment Share on other sites More sharing options...
perryg114 Posted January 24, 2010 Author Share Posted January 24, 2010 Does anyone have a factory shop manual for a 96 subaru legacy wagon. Any Legacy with a 2.2L would probably work close to this year. Usually you set the output voltage to something like 5V with the throttle closed.

subikid90 Posted January 25, 2010 Share Posted January 25, 2010 I have the Haynes Manual and all it was is "when installing the throttle position sensor, be sure to align the socket locating tangs on the sensor with the throttle shaft in the throttle body", then says "installation is the reverse of removal." I dont see anything about setting the voltage to 5V. I hope this helps. -Subikid90 1997 Legacy GT 5spd & EJ251 w/EJ25D heads ~10.5CR 1998 Legacy GT Limited waiting for EJ22T hybrid swap Link to comment Share on other sites More sharing options...
perryg114 Posted January 25, 2010 Author Share Posted January 25, 2010 I got subarupartsforyou.com to send me the page out of the factory shop manual. I bought the part from them. The manual says rotate the TPS until the voltage with the throttle closed is .45 to.55V on the the output side of the TPS. I am assuming that 12V goes in and .5V is coming out with the throttle closed. When you open the throttle the voltage will go up towards 12V. I ment to say .5V before not 5V. It says to remove connector B84 on the ECM and measure voltage on pins 24 and 25 with the key on using a volt meter. I would think you could pic the voltage off of the TPS at the plug using a stick pin stuck in the lead wires etc. Some OBD-II readers may also be able to measure the voltage. Now at least I have some calibration to shoot for. This is why I always get factory shop manuals whenever possible. The aftermarket manuals don't tell you the fine points of how to test a sensor and what the nominal values are. Perry Link to comment Share on other sites More sharing options...
