I recently became a owner of my first Subaru. But it has problems. Its throwing 2 codes. P0500 and P1101. Ive got the 1101 taken care of, in so much as i have the correct part. now when it comes to the 0500, which i'm told is the speed sensor, I have a couple of questions. I went the auto parts store and they told me that my car has 3 sensors. After a couple of days I opened my repair manual and started reading and the manual tells me that I have 2 sensors. One in the transaxle and the other is somewhere behind the instument panel. Who should I follow the store or the book. And how do I know which one the change. or do I have to change all of them. The car dies all the time, even when driving down the highway. The speedodometer works fine. So I believe the one i need to change is the one in the transaxle, if I am following the book. Please help trying the get as much knowledge as possible when it comes Subaru. Like I said i'm a newbie.
