I’ve been reading every forum I can find and watching videos on YouTube and I feel that I have a good understanding but would like a second input.
to start I have a ccsb 04.5 6.0 auto 4x4
I’ve been chasing cel so I can smog and reg it and get it back on the road.
current issues I’m running into are
P0113
P0237
P0488
P0603
P1000
P1102
I started by setting my edge cts2 in the engine bay so I can read diagnostics.
Map was at 14 psi KOEO so I blew through the hose and I could get up to 16 psi. I still took off the sensor a cleaned it and now it’s stuck at 3 psi and will not move. I replaced the hose while I was there.
After that I pulled my air box to get to my EBP sensor and tube, I cleaned them both but they are stuck at 0 psi KOEO, driving, and idling.
Baro sensor is reading correctly
I inspected my CAC boots and they are oily and look to have micro cracks.
Have not yet tested vgt solenoid but will be doing soon. Vgt % stays at 0 KOEO driving and idling.
My current plan is to install new Map sensor, Ebp Sensor, CAC boots, fuel filters, filter cap, IAT sensor and pigtail, battery terminals.
I have installed Icp sensor, Ipr valve, batteries, and fresh oil change/filter.
Anything else I should be checking or replacing? And way I can load test the sensor pigtails to see if they are grounding out anywhere?
Ideally I will be getting oem motorcraft parts off rock auto and other parts from riffraff.
Truck fires up quickly and as far as I can tell it sounds fine. I don’t have loss of turbo but it surges on acceleration until fully warmed up.

 

Since the VGT %Duty Cycle is a command only, I do not believe your CTS is giving you the correct VGT %DC reading. 0% is not a valid command.

 

Lots of open circuits short to power short to ground codes DTC etc..

I don’t believe all those sensors went bad so it’s a roll of the dice to change them

a lot of these codes are sensor:actuator that share vref circuitry check that and signal return circuitry

 

The EBP can be reported in "GAUGE" pressure or "ABSOLUTE" pressure.

You need to know which PID you are looking at to know if it is an issue or not. The EBP_G (gauge pressure) SHOULD read "0" at KOEO. The EBP_A (absolute pressure) should read atmospheric pressure at KOEO (same as Baro). The MAP sensor is by definition reading "ABSOLUTE" pressure (same as Baro at KOEO).

IMO the codes indicate a possible v-reference short at the MAF sensor. Wiring, bent pin, etc. This can impact the MAP sensor if the signal return circuit (common circuit) is damaged.

The MAP and EBP sensors share the same v-ref circuit.

 

Here’s a diagram
i can’t get another schematic to load

 

I was able to use a snap on scanner, my ebp psi is at 14.9 and my ebp v is at 0.94 KOEO.
