so today i had my all trac act up on me. When i start her there is no code but when i gun her she kind of bobs and then picks up and then throws a code. Shes not pulling as hard either. Shes throwing code 42 which is vehical speed sensor unit. Now mind you, when i turn her off and back on i have no check engine light on. Shes also throwing 54 at me but i dont know wut that is.
code 54 isn't in there. I read somewhere it could be a knock sensor code. Does that mean i have a freakin knock?
http://www.celicatech.com/imagearchive/ ... /FI/FI.htm so code 42 is defeantly the speed sensor signal. Would that cause my problems? fix? code 54 is intercooler water sensor, thx mafix.
i suppose so but that doesn't explain my symptoms. I pulled the efi fuse and havn't had a problem since so idk, my car sucks.
your speedo controls the VSS and your intercooler level might have been low. sometimes the ecu doesn't use the VSS but you still need it.
