hey,
i done a little research and found its something to do with the Engine RPM. Something to do with the signal.
I dont know how to fix it but thats what i found,
good luck fixing it,
Jamie

31 is non conclusive if engine not running.  If a V6, do test again with engine running. If no 31, then its OK, if the car won't start, inconclusive (v6 won't start without crank signal).

A 19 is the one that definately means knackered crank sensor

Not something I've seen before.  31 is no rpm signal. No rpm signal results in no spark or fuel on v6...

Change the sensor anyway...
