I went for engine wash and upon starting the van, it starts with fluctuations in idling but lacks acceleration and low engine power. Codes after scanning are p2110, p2104, p2107, p2112, po220, po708, p1200.I then bought a new pedal, a used throttle body. The vehicle now start with stable idle but no acceleration and now left with codes p2112 and p2104. If I put on the ignition without starting and press the accelerator pedal the throttle plate opens according to how I press but immediately I start it it went back to close position and I was told adequate fuel is not entering the injectors. The throttle wrench light is showing on the dash board.I have used another PCM from the same model, it start but cannot accelerate. Please help me out from this limp home mode. Thanks

Put your old pcm back as you cannot exchange these units. It has to be flashed to your specific vehicle.
Did you remove the battery cable to clear the memory for the pcm?
I am concerned that your used throttle body is the issue here.

Thanks a lot.I have fix back my own pcm and I used my scanner to clear the codes p2112 and p2104 but they keep coming back but I dont know how to clear the codes using the battery method but I always remove the battery head evryday I also find out that enough fuel is not getting into the injectors the code Po193 use to appear frequently before but when I checked the fuel pressure sensor and plugged it in well the code dissapeared ever since or what could make enough fuel not get into d injectors and why will the throttle plate open at ignition on and remain closed after starting the engine. Thanks

Everytime you turn on the key, the fly by wire system tests itself. Thats why you see the throttle plate move.
If there is an issue with one of the motors on the throttle body, it will code. It is a common failure. The pedal sensor is also an issue. We always recommend replacing both together when issues like this come up. I would look at these first before moving on to the fuel control issue.

Thanks. Now that the TB seems to have no problems if I get you right, what can be hapenning to the fuel issue since it is confirmed that enough fuel is not entering to the valve or injector and was told it is lack of current. What could be done?Even when I touch the

Are you sure the throttle codes are gone? Have you road tested it for a complete drive cycle to confirm?

No, the p2112 and p2104 codes are very much present. What I am saying is that what is actually the problem?Where else should I try after checking lots of things and no solution. Is it the lack of enough fuel entering into the injectors that can bring this codes or the PCM is reducing the fuel supply or what do you think is the real cause of this. Thanks

What happens is the throttle actuator has a problem and shuts down closing the butterfly so the engine doesn't go on its own.

Here is a guide and some diagrams (below) on how to fix the van by replacing the throttle actuator.

and

Clear the codes once completed.

Please let us know what happens.

Cheers, Ken
