P0122, P0101, P0245

Hello guys,
I have the following DTC and my vehicle is in a limp mode with a highest rev of 3000RPM
P0122, P0101, P0245 OBD2 generic codes

Mercedes Benz sprinter 2007

I have swapped the pedal with another pedal and problem persists. I have swapped the N75 wastegate solenoid with another and problem persist

The pedal is a 6 wire sensor and this is what I’ve done so far
1. 5v
2 Signal 1
3 0.03v sensor ground
4 0.01v. Ground 2
5 Signal 2
6 0.01v

I have a SRS dashlight that I’ve not cleared, wondering if this could cause all these codes.

How do I attack these DTCodes

Warm regards

Update

There are 2 (5v) reference circuits on the APPS

1. 5v Red/yellow wire
6. 0.03v White wire
3. Yellow/brown sensor ground 0.03v
4. Brown/white (ground 2) 0.03v

So I guess I have a 5v reference short to ground on pin 6 the white wire
My question is can I just run another wire directly from back of the ECU harness, since the sensor is directly connected to the ECU. I can’t find any wiring diagram showing how many sensors sharing this 5v reference wire. My plan is to cut the wire into two at the ECU harness connector if I can find my 5v there and then run a direct wire to the APPS, more or less cutting off the trouble part of the wire. I would appreciate any help on this.pls note my TPS and MAF both have 5v

I don’t think I have the time and energy to chase a shorted wire.
See pix below

I still have the P0245 and P0101, but let me start with the P0122

Hope to hear from this wonderful community

So I went to back probe the ECU and got these readings

Note I’m back probing the wires I believe are the two 5v reference wires of the APPS

1. Yellow/red 4.99v. C2 connector pin 15
6. White 0.01v C2 connector pin 12

I even did white and red for TPS and got 4.99v

How do I address the 0.01v on the white wire at the ECU. Note the reading at the APPS connector KOEO of the 5v reference wire is giving 0.01v

I did a short to ground ohms test and got OL when my meter was set to 20M, and 76.5 when my meter was set to 200M

What’s the way forward guys
Need your help

Update: I have back probed the ECU and also cut into 2 the white wire to take my reading Incase of a short farther down the connector and it’s still reading 0.01v

The wiring diagram shows no other sensors are sharing the 5v

Anyone willing to help on this pls?
