Hello, does your scan tool monitor any data at all? Like EBP, map, or mgp?

When driving what is the highest the map reading goes up too?

Ask Your Own Ford Question
Customer reply replied 2 years ago
14 psi range just atmospheric pressure
Customer reply replied 2 years ago
The map really doesn't go up or down from idle to wot
Ford Mechanic: James, Ford Technician replied 2 years ago

I would remove the map sensor hose going to the intake manifold. Look to see if it is plugged up with carbon. I would also double check the CAC tube connections to make sure they are secure and not leaking.

Ask Your Own Ford Question
Customer reply replied 2 years ago
Already did both no change
Ford Mechanic: James, Ford Technician replied 2 years ago

does your scan tool show VGT learn? If the MAP isn't building past 14PSI there is a large air leak somewhere. do you have another map sensor you can try incase it has failed for some reason.

Customer reply replied 2 years ago
Ive replaced the intake gaskets,map and the vgt on the turboThe truck will make boost if the map is unhooked
Ford Mechanic: James, Ford Technician replied 2 years ago

When the work was done was the battery disconnected. The reason I ask is the 03 has a turbo relearn procedure. It usually lets the vehicle sit outside and idle for about an hour.

Ask Your Own Ford Question
Customer reply replied 2 years ago
tried that too
I've even unhooked the batts a second time over night and let it idle
Customer reply replied 2 years ago
I'm going to check some of my other ideas today
Ford Mechanic: James, Ford Technician replied 2 years ago

Sounds good. Does this have a programmer installed by chance?

Ask Your Own Ford Question
Customer reply replied 2 years ago
Nope never needed or wanted one
Customer reply replied 2 years ago
Could it be the PCM ?
Ford Mechanic: James, Ford Technician replied 2 years ago

It's possible. If you rev the engine to 3500rpm in

Ford Mechanic: James, Ford Technician replied 2 years ago

In park what does the EBP read?

Ask Your Own Ford Question
Customer reply replied 2 years ago
Nothing reads blank
Ford Mechanic: James, Ford Technician replied 2 years ago

That can be the reason you aren't building boost. Does it read anything with key on engine off. With should be within 1psi of the map psi

Ask Your Own Ford Question
Customer reply replied 2 years ago
Nothing
Any time
Ford Mechanic: James, Ford Technician replied 2 years ago

If the EBP isn't working that explains why you don't have any boost. I would double check the sensor connections and replace if needed to repair the concern.

Ask Your Own Ford Question
Customer reply replied 2 years ago
The connection are showing voltage and a signal
And I've tried two sensors no change
Customer reply replied 2 years ago
Now why would it make boost with the map unhooked ?
Ford Mechanic: James, Ford Technician replied 2 years ago

You building boost when you unplug the map sensor?

Ask Your Own Ford Question
Ford Mechanic: James, Ford Technician replied 2 years ago

if your getting a reading with a meter then the scan tool can't see it for some reason. If unplugging the map sensor builds boost it can be a defective map sensor. If these parts weren't replaced with motorcraft parts it makes a difference as well. Off brand parts have high failure rates on powerstrokes.

Ask Your Own Ford Question
Customer reply replied 2 years ago
I've tried two maps
One ford and a off brand
Same thing
Ford Mechanic: James, Ford Technician replied 2 years ago

Something is incorrect. What voltage reading do you get key on engine off.

Ask Your Own Ford Question
Customer reply replied 2 years ago
Voltage on the map ?4.96 volts
Ford Mechanic: James, Ford Technician replied 2 years ago

When you unplug the map sensor what does the scan tool show for psi?

Ask Your Own Ford Question
Customer reply replied 2 years ago
I haven't checked that since i got my scanner to read right
For boost never goes more then a psi or so
Ford Mechanic: James, Ford Technician replied 2 years ago

Correct I'm wondering if the map sensor is defaulting when unplugged to read a high pressure

Ask Your Own Ford Question
Customer reply replied 2 years ago
2.8 map minus 11.8 boost
Ford Mechanic: James, Ford Technician replied 2 years ago

Unplugged you get 11psi of boost?

Ask Your Own Ford Question
Customer reply replied 2 years ago
Negative 11psi so vacuum
Ford Mechanic: James, Ford Technician replied 2 years ago

That is odd. You shouldn't have boost if that is the case. I would recommend updating the PCM if you had a chance.

Ask Your Own Ford Question
Customer reply replied 2 years ago
A reflash?
How would i know if its been done ?
Ford Mechanic: James, Ford Technician replied 2 years ago

There have been so many updates over the years. If it hasn't been to a dealership in the last year. Most likely it hasn't been done. If you have a scan tool that could pull the PCM part number it could tell you as well.

Ask Your Own Ford Question
Customer reply replied 2 years ago
I dont see how a reflash would help a no boost problem
Ford Mechanic: James, Ford Technician replied 2 years ago

Ok.. Well this isn't something I am able to repair without physically being there. I will opt out and maybe someone else has an idea.
