Trying to map the EGT PID sensor numbers for the 3rd gen ED with physical location, to monitor with Torque Pro. TP shows 4 EGT PIDs. I get temp readings on 1-3, but a constant -40F on 4. Got the Rebel on my lift and took some pix of exhaust sensors. Pic1, 2 sensors on the exhaust pipe between turbo and DOC/DPF. I believe one is the upstream NOX sensor, the other EGT1? Pic2 of DOC/DPF part shows 4 sensor ports. Two of these are sensors for DPF delta pressure, one in middle and other at EGR return T. Is there also an EGT in the middle, EGT2? What sensor would be in the port in front of the DOC (top of pic2)? Pic3 sensor is post-DPF. Most info I see says this is EGT3, the indicator of an active regen with temp>1000F. Pic4 shows 2 sensors post SCR, downstream NOX, the other?
Can someone help pin this down?
