APPS/TPS in '04 3500 Ram problems...
 

I hope someone can help me! Apparently I have a rare APPS that mounts under the battery box on an '04 5.9L 24V common rail engine. I have been searching the web for hours and can't find one exactly like it. How do you test this type? It has six little, male, needle-like pins down in the plug cavity that I can barely see, let alone probe. I don't know which pins to probe to test the resistance, or what the typical resistance values should be. Does anyone know how to test, or where to find one of these elusive sensors? I'm kinda stumped here. Any help would be of great value. Thanx!
