Hello chaps keep getting engine warning light come up so this morning done a check using clip on TE1 and E1 in diag port and got code 42 again ever since having the car she keeps throwing code 42 up and have checked what code means and it is:

 

42=No 1 Speed Sensor Signal Circuit

Open or short in no. 1 speed sensor circuit

telltale light RH (LH)

no.1 speed sensor

ECU

 

I have no idea why keep getting this code as the car runs great and have reset the ecu twice now and code goes away for while then comes back, could anyone please explain why and how to stop the engine code keep coming back?:(
