hi, so i was taking a drive the other day in the rain and i got the powertrain warning light turning on and off and a beeping noise, there has been no prior issue in my time of owning it but when i used an OBD a P1934 VSS (validated fault has been present during this drive cycle) error came up which i thought could be the cause of the powertrain light?

other than that i have not had any issue with the power feeling reduced (limp) or any transmission issues other than it struggles to go into reverse sometimes but i think thats just a old abused car thing hahaa. 

if anyone's got any ideas that would be really helpful

just want to get it fixed and even if htat means just take it to the mechanic because we cant fix it at home then so be it. i also believe that there could potentially be a wire that has snapped or been chewed through as we had that problem with the alternator plug. thanks people! 

the car specs incase you cant see them from my profile:

ford fiesta 2006 
5 door 1.4TDCi durateq
 

P1934 is a speed sensor fault so get the ABS sensors check on the wheels
