Speed Sensor A Fault

[nengelbrecht6]

Been getting the following fault code from the IID and finally deciding to do something about it:

 

P0501-62 (E8) Vehicle Speed Sensor A range/performance - Algorithm based failure - signal compare failure

 

This is accompanied with "Engine System Fault" and "Cruise Control not Permitted" messages.

 

I am assuming this is pointing to a fault in one of the wheel speed sensors, but which one is "Speed Sensor A"?

My speed sensor failure told me which wheel, but it also shut down a bunch of systems. I had no speedo, air suspension, or traction control

I'll check with our rover software tomorrow and get back to you with an update.

That's a bit odd - I haven't seen an 'A' sensor before.  Usually it tells me LF, LR, etc

I don't lose any functionality when I get the error. Only thing I lose is the ability to use cruise control. And I get the annoying "Engine System Malfunction" warning message that continually appears.

 

 

Yesterday on the way home I got the same "Engine System Malfunction" message, so I plugged in the IID. This time, no speed sensor fault. Not sure now if the warning message is being caused by something else, but I don't have any faults coming up on the IID. And I haven't lost any functionality. Just the annoying message.

Justin,

 

Pulling up an old thread, but can you check this out and let me know? Still getting the same error code from time to time.

 

Thanks,

Nick
