When the FMI is 10 , it means the signal isn't completely dead (which would trigger an FMI 03 or 04 for voltage out of range). Instead, the ECU is seeing a signal that skips, drops out rapidly, or fluctuates in a way that is physically impossible for a mechanical crankshaft, pointing to an electrical or physical reading error. Primary Symptoms of ECU 636.10
Constant heavy-duty use can crack the internal solder joints.

Before buying replacement sensors, check the physical environment. Locate the crankshaft position sensor and the high-pressure fuel pump connection area. Search the wiring harnesses for signs of rubbing against the engine block, cracked insulation, or pinch points. Unplug the sensor connectors and look for green oxidation or water intrusion. 2. Check for Accompanying Codes
. While "ECU" in automotive contexts usually stands for "Engine Control Unit," in this specific search hit, the "63610" identifies the unique story ID in the DOTmed news database. Bruno Lempernesse
In rare cases, it isn't the sensor's electronics acting up, but rather physical timing. Wear on the camshaft gear, a loose timing chain/gear, or problems with the high-pressure fuel pump (on common-rail injection systems) can cause the sensor to read irregular rotational speed.
