Hoping to grab some assistance regarding an issue pertaining to the Loss Of Signal from the Secondary Speed (Camshaft) Sensor

This is a stretched frame Day Cab - Toterhome that we built entirely from the ground up .
This is the last issue I have before I can send the truck down south to have the body built .

I have confirmed there are no shorts to ground , no resistance inside of the harness & The pin out is correct .
The sensor was swapped with a replacement to no avail.

I popped the peanut cover off and confirmed the cam gear is timed correctly , popped cam gear out and confirmed there is no damage to the tone ring side of the gear .

I am hoping that someone has had a similar issue and they can share what worked for them. Thanks in advance

Looking for some assistance regarding an EGR Cooler Temperature Issue , engine is an MX13

EGR cooler spikes in temperature the second truck starts rolling

While stationary, With wide open throttle never passes 270 degrees without cooling itself off

While stationary, During regen never passes 270 degrees without cooling itself off

When the truck is loaded and rolling, the temperature in the EGR cooler spikes rapidly and peaks at around 500 Degrees . The second you let off the throttle, the Temperature drops rapidly, when throttle is applied, it spikes again.

I have already done a significant amount of diagnostics and have not found the fault.

So far the data on the temp sensor was checked and verified, swapped with a test sensor regardless, EGR valve ECU request and actual are on par with each other, regardless Valve was replaced with a test unit, the cooler was removed , inspected and cleaned, I popped the thermostat housing and made sure both thermostats weren’t fucked up .

Would appreciate any suggestions, this is a rather odd issue . Thanks in advance
