Engine rpm sensor has a fault. Likely stall guard will not function.

Thanks. Is it something I can fix or do I have to take it to a dealer?

If it just a sensor then it is not too difficult.

Could it be the tachometer cable became disconnected or broke? Does it even have have a tachometer cable? Where is the sensor located?

No tach cable. All electric. I will have to look at mine but I think the tach sensor is on the front of the injection pump. Check for loose connectors.

You are right. It goes in the block just ahead of the IP.
