i have a 94 accord ex and when ever i turn the car on in the morning to drive it to work the speedo just jumps irraditically all over the place and as soon as the it shifts into second when im driving the code goes off for tcu code for which i believe is speed sensor not gettting the right info from the speddo but i have changed the speed senor and the problem still insits so my question would be is it the speedo itself or is it something else also i owned two accord before this all 94's and i could've sworn they all had cables sensors and this one does not so a liitle confused there but i could be wrong
