Huh?

 

Left the battery off over night but still got the error?

 

Speed sensor is working fine however as the readout on my infometer shows the correct speed all the time from the ecu.

 

Anyone else had error 14?

Hmm looks like its not going away, battery left off for 12 hours and it still getting the error. Speed still reading ok though?

 

Someone must have had error 14?

Thats an odd one.

 

If your speedo is working and the Informeter is reading the speed from the ECU then the Speed sensor circuit from the Gearbox to the Clocks, to the ECU must be fine.

 

If your PAS working ok ? Hicas light coming on ?

 

It does'nt put the car in safety mode of anything like that so you dont have to worry there, the only concern would be with the PAS and HICAS but if they are fine too.....

Pas seems fine, my hicas is reamoved and so is the bulb

 

since I last put my clocks in my speedo has been intermittant at times, however the informeter was still reading correctly from the ecu

 

just odd how the code is still there after clearing the ecu and not even starting the car, maybe my clocks are causing it, speedo and informeter still working fine at the moment tho.

Try turning the ignition on and off 50 times to see if it clears the code but dont start it obviously or youl just screw something up.

Yeah might try the ignition 50 time then see if the code clears

 

I'm thinking its a fault on my clocks

 

Does the signal go from the speed sensor to the clocks then the ecu then?

 

As my ecu was still reading fine while my speedo was reading 0 so i just thought it was the needle acting up etc

Turning the key 55 times didnt help

 

But driving home tonight I saw that my speedo was saying 20mph and my gps and ecu were saying 45mph. Then the speedo suddenly jumps upto 45.

 

So the signal must go from the speed sensor to the ecu, then clocks then back again?

>> So the signal must go from the speed sensor to the ecu, then clocks then back again?

 

no, the speedsensor provides the signal for the clocks, the clocks convert the signal (to a pulse signal) and send it to the ecu...so the ecu is last in line.

So if you have a persistant code 14, my first suspect would be the clocks.

even if the informeter or whatever diagnostic tool reads the speed correct, there still can be an abnormal/stagnating signal from the clocks to the ECU.
