I replaced my vechical speed sensor twice, and that did not help my problem. One of the mechanic told me that it is probably my plug off my wireharness, and that it is eroded because he saw some white stuff. Is there any possible way i can purchase the plug by itself, or i will have to buy a whole new wireharness ?

 

What kind of car? Just go to the junk yard and take the plug off another part of the engine. Only speed sensor I had to replace was on an accord automatic, and I noticed that a few things in the engine bay share that harness.

 

Are you getting a CEL?

 

rip one of a car like quadnie said. thats your best bet
