Subaru45895 Posted May 11, 2005 Share Posted May 11, 2005 I own a '90' Subaru Legacy. I checked the codes on the transmission. The Speed Sensor and Solenoid C codes appear. Is it possible if the Speed Sensor is bad that I would get a false code for the solenoid? What is the easiest way to check the Speed Sensor 2? Thanks, Dan Link to comment Share on other sites More sharing options...
Legacy777 Posted May 12, 2005 Share Posted May 12, 2005 Hey Dan, It's very possible the speed sensor could have caused the duty c solenoid code. What symptoms/problems are you getting? Or just that those codes are displayed? If you're not having any problems, I'd just clear the codes, pull the egi/tcu fuse, and just keep an eye on things.

Subaru45895 Posted May 12, 2005 Author Share Posted May 12, 2005 Hi Josh, The car has an automatic transmission. Sometimes it would hold in third gear to long. That would happen only when car was first started. Then I noticed while turning right that the right back wheel wanted to drag around the corner. After all of this happen, then I got a flashing power light on dash after starting car. I checked the codes and that is when I got code 24 & 33.

Legacy777 Posted May 14, 2005 Share Posted May 14, 2005 The TCU holds the gear in 3rd when trans temps are very low, so the fluid heats up faster. So this is normal during the winter time when temps get really low. Link to comment Share on other sites More sharing options...
Subaru45895 Posted May 14, 2005 Author Share Posted May 14, 2005 That is good to know when it is cold out. What is the easiest way to check speed sensor 2? Link to comment Share on other sites More sharing options...
Legacy777 Posted May 14, 2005 Share Posted May 14, 2005 You can tie into the VSS2 signal at the ECU or TCU. it should be an oscilating 0 to 5v Here's the pin out for the ECU & TCU http://www.main.experiencetherave.com:8080/subaru_manual_scans/FSM_Scans/ECU_I-O_page1.jpg http://www.main.experiencetherave.com:8080/subaru_manual_scans/FSM_Scans/TCU_I-O_page2.jpg Link to comment Share on other sites More sharing options...
