Im working in reading right now TB so could be a challenge but its not a bad idea (its very handy having you close by I must try not to abuse the service ). I guess its possible that I've just been unlucky and had 2 failures.....

It would prove for def if the code occasionally needs to be cleared after reapir.


As for the 20 starts thing, when my crank sensor let go, immediately upon replacing it, it reverted to a 31 (the only diag tool I had then was a paperclip), so I think it should show as fixed instantly.

I've never had a 31 out of mine, even before the sensor failed :-/ :-/

unplug lpg ecu and see what happens then?

Ooh... That's an idea. Why didn't I think of that

I know the sensor was starting to fail before I fitted the LPG so that definitely isn't the cause but could be why the code's still showing

The only thing the lpg might do is to introduce some electrical noise due to switching of injectors. Worth eliminating but unlikely I'd say.

RPM signal is an output from the main ECU and not connected to the crank sensor signal, which is a high resolution tooth pattern rather than a "once per bang" pulse.

I love it when we can get such accurate description so quickly!

Worth eliminating but, as you rightly say, unlikely to be the cause.... This one's got me a bit baffled :-/ :-/

Nor have I. Engine off, ignition on, paperclip in 12 12 12 19 19 19 and repeat....
