so i have this little problem with my truck.the speedo still isnt working and the check engine light is still on. i ran another obd-II diag. test on it and it said that the speed sensor is malfuntioning. heres the catch, i replaced the speed sensor about 3 weeks ago when i first ran the diag. test on it. could there be something wrong with the connection to my speed sensor? if so, how would i go about checking this. i have to get my truck smogged before the end of the month, and itwont pass ifthe check engine light is still on. please help me! this is getting really frustrating!</P>

try to find where the wires run from the sensor to the PCM and check for contenuity....did you check the connection at the sensor for dirt or corosion?

 

ok....so im dumb. when i replaced the speed sensor, i replaced the one on the tranny. not thinking to ckeck the one on the rear axle. it would make a lot more sense to replace that one though because my brake/abs lights are on. man am i slow. oh well....hopefully tomorrow all my troubles will be over!

 

When a fault code is given, it simply means that somewhere within that circuit, in your case the speed sensor circuit, it has fallen out of the acceptable range of operation. It is usually the sensor, but sometimes it's ,as said above, a bad or dirty connection or a wiring problem to or from the sensor.<img border="0" src=smileys/smiley2.gif border="0">

 

Disconnect the plug from the ABS computer and blow all the water out of both ends.

 

thanks for the help. i tried cleaning out the plug with some compressed air, but that didnt do it. its no biggie though, i talked to the service rep. at my local dealer and he said the part is only $35 and super easy to install. looks like ive got somewhat of a project for my day off work tomorrow.

 

aahhhhh....all better.....replaced the rear wheel speed sensor and all my problems are done with. what a relief.

 

glad to hear everything came out ok!
