Ford Repair Questions? Ask a Mechanic for Answers ASAP
The vehicle is running fine there is just no power? Is this correct?
It will shift harder if it isn't building any boost. If there are no exhaust leaks I would suspect you have faulty map sensor or a restricted map sensor hose. I would also make sure the impeller vanes aren't damaged at all.
The only way to eliminate the map sensor is to swap it out with a known good one. Do you have a test light and we can see if it's getting power?
This turbo is fixed. Without the turbo operating this vehicle has trouble just to get up to 25 mph. Since the turbo is fixed the only thing that will affect it are exhaust leaks or air leaks. The map sensor of course. I will try and get the correct diagram for the map sensor. It's been a long day but I believe it gets 5volts from the PCM.
Make sure all exhaust manifold bolts are loose if they are loose you can lose boost? Is the turbo you used an own replacement?
On this vehicle messing with fuses shouldn't affect power. All sensors are a 5v reference.
I don't see anything wrong with any of the photos. Are all charge air cooled tubes still in tact and tight?
The only way to test the wires is with a multi meter. If you had a scan tool to monitor manifold pressure to see how much boost is actual building. Low fuel pressure can cause this concern.
It very well can be producing low fuel pressure so it seems like the turbo isn't working correctly.
That can do it. If you were unaware of it had a programmer installed ever it very well could be the issue.
