Did a little research and found this from the 1996 manual I had squirrelled away (digitally) and found.
Exhaust Back Pressure (EBP) Sensor
The exhaust back pressure (EBP) sensor is a variable capacitance sensor that, when supplied with a 5 volt reference signal from the powertrain control module (PCM) (12A650), produces a linear analog voltage signal that indicates exhaust back pressure.
The powertrain control module uses this signal to control the exhaust back pressure device when needed.
Thats it, thats all I guess, least according to the '96 manual. I thought it would be peddle position that would determine on/off (as well as EOT) of the EBPV, referred to as the back pressure device above.
I know on my white/silver stock truck it comes on (EBPV) now that it's cooler out, laughed out loud the other day as I had totally forgotten about this "feature". It wouldn't come just after startup or idle but when I had depressed the peddle a bunch like at 40 kms (30mph) almost seems to stay on at too high an RPM. Anyways when I get time will be "modifying this feature" right off the engine....EBPV, actuation cylinder, piston assembly too and related keerap.
