Engine speed sensor code

[AO299D]

Hello I have a engine that brings up code 190-8 since it was rebuilt I put a new senser on and that didn't help attached are some graphes that might be helpful

It's on a cat TL1055 telehandler
S\N TBM00416

Engine number is 292-5307

Might it be a grounding issue?

See if the attached gets you anywhere. You may also need an electrical schematic.

Have you tried to pull the sensor out and pass a metal object in front of it while watching the graph? If the sensor works well you could check to see if the sensor is too far away from the crankshaft gear and is not getting good detection of the gear.
