ICP Sensor Rust Jacking

These Camshaft Position sensors from 6.0L Power Strioke diesel engine show what happens when an engine block rusts under the sensor and pushes it slightly out of the block. This creates weak CKP signals and no start conditions. Technicians skilled in using an oscilloscope can easily diagnose this. If you cant see it, the sensor on the left is bent at the mounting base up top.
