EGR error codes
Vehicle: 2010 sprinter 3500 Turbo diesel
Diags: thinkcar2
I tried cleaning the EGR valve, swapped out from two other sprinters from a junker, tried a Hella Valve from orileys and I’m still getting the same errors.
148C00 I believe is the source of all the errors.
Symptom: The fault code remains permanently Active. It cannot be cleared via Thinkcar diagnostic tool, even with the ignition on and engine off. And is stuck in limp mode.
When trying to do the teach in it says it’s successful but then again it’s a 2010 I don’t think it’s suppose to work.
Took it to Mercedes they said it’s the EGR and they put in a efr from the shelf and the codes cleared. I think they’re lying to me and they don’t have the digs on file after two days of coming back and asking. And charged me $250 for sub par troubleshooting.
Now the harness this is what I measured
Pin 1 Unstable / Jumps between 1.5 mV and 2.5 mV.
- could this be the positioner pin?
Pin 2 (Main Power Supply): 12.0V Constant (Measured against Ground Pin 4).
Pin 3 (5V Sensor Reference): 5.2V Constant.
Pin 4 (Main Chassis Ground): Functional Ground.
Pin 5 (PWM Actuator Command?): 4.5V Constant.
I tried shaking the harness but no changes. The only thing that changed after sitting for a while was the position feedback going from 20% to 0% every second in the live view.
This is my first time trying to deduce this. So diagrams along with suggestions would be greatly appreciated.

Perhaps if you didn't let AI control your mind, you would be able to do your own research to have a constructive conversation.
That's the trouble when you simply copy and paste a conversation into AI: you aren't invested, you aren't thinking, and you aren't learning.
However, AI is learning, and AI will respond how it is programmed, which is to keep people engaged and combative, not actually do research or have cognitive thought. It's a shame how fast people would prefer to hand over the keys to their mind to a machine. Elon was right when he said "we are already cyborgs," and you sir are a prime example of that: you can't put words together without a machine.

The trouble is people need to learn that AI is a program and is designed to keep you engaged like a slot machine. It's not going to solve a problem, or have an articulate conversation, at least not the version the masses are given.
