backyard mech Posted October 19, 2009 Share Posted October 19, 2009 I get a tcu code 33 and the cruise control doesnt work. Any ideas? I know the code is vehicle speed sensor #2. how hard is it to fix. I rebuilt the transmission a year ago and it seems to have always read this code. 90 legacy ls 2 wheel drive automatic.

johnceggleston Posted October 19, 2009 Share Posted October 19, 2009 (edited) the speed sensor is on the passenger side of the trans where it meets the engine near the firewall. it has a cable coming off of it running to the speedo. it could be disconnected, the cable could be broken, or the sensor could be bad, or maybe the "drive" gear in the differential is bad. take a look.

backyard mech Posted October 19, 2009 Author Share Posted October 19, 2009 the only cable is the speedometor cable. Is there a wire there ? didnt see one , the speedometer seems to work ok . I feel like im missing something. Link to comment Share on other sites More sharing options...

I feel like im missing something. how did you read the code? are you sure it's a 33? a tcu code is different than a ecu code for a check engine light. but you are probably just using the wrong term. what all did you do when you rebuilt the trans? it kind of sound like it's looking for the other speed sensor that ti would have if it was AWD. check the wire connector that plugs in the trans to the car harness, on bell housing above speed sensor. look for bent pins? i just double checked, an ECU 33 means the same as a TCU 33, VSS #2.

backyard mech Posted October 21, 2009 Author Share Posted October 21, 2009 I get a code 33 from both the ecu and the tcu. the pins are fine in the plug. vss2. I was told it was in the instrument panel but not sure where. Is the speedometer cable the vss2? There is no wires where the speedometer cable plugs into the transmission Link to comment Share on other sites More sharing options...
