Default Electronic throttle control light

My electronic throttle control light has been on a few times....the lightning bolt in a plenum symbol on the dash. Seemed to be related to the alternator, a bad battery, and poor connection from alternator charging wire.

This time, driving along I got a chime and check engine light along with a blinking throttle light and a "hickup" at that moment.
Kept going fine, no power loss, and a restart cleared the throttle light.
Haven't checked the code yet. Research shows 106 is common.

Now, I know there's no "throttle" so I take it this refers to the apps...?
Unless its something to do with that valve dohickey on the egr circuit..? Which is unplugged for the delete.

Anybody delt with this?
New apps in my future??

You need to pull codes, there are actually quite a few things that can turn that light on.

192 says rail pressure sensor "A"circuit low voltage
Haven't had any other performance issues since changing the lift pump a few months ago.
I would think I cleared codes after that, but can't say for sure.
652, low voltage at the #1 sensor supply circuit.
I'm sure I have not cleared codes since the alternator and battery issue, so it could be a leftover I suppose.
63D Alternator input high
62C Vehicle speed performance
61A Level 2 torque performance

Another episode last Friday.
P0192...voltage
P0652...voltage
P1011...low rail pressure. (I did stand on it a little that morning & the check engine light came on)

Changed the battery cable end and cleaned and sealed the alternator and solenoid wires to the passengers battery.
We'll see what happens...

Definitely an issue with the fuel rail pressure sensor or wiring to from the engine ECM to the sensor. You may want to try wiggling the wiring at the rail pressure sensor connector. That sensor connector seems to have a high failure rate, alot of times the inside of the connector will have a brown dusty appearance. If it does I would suggest replacing the sensor and the pigtail. The Cummins part # for the pigtail is 3164101

The 5v reference for the fuel rail pressure sensor also feeds the cam sensor, crankcase breather pressure sensor, and intake air temp/pressure sensor, so a chaffed wiring harness to any one of the those sensors could cause problems too. In my experience the issue is usually at the fuel rail pressure sensor, but the engines I work on also have the gear case at the opposite end of the block lol.
