Car not starting Codes P0638 and P1523

Hi Ken
Thank you. I have tried starting it with the accelerator pushed down at various levels. With no joy. (Once again it its very close to starting.) The butterfly in the throttle body does not move and remains shut. The only time I have the butterfly move is when I first turn the key to on and the butterfly gives a very small flutter back and forward as the ECU goes through its check.
The information you have provided is great. However, are you able to have another look for me to see if you can locate the wiring schematics for the particular model I have? It is a 2003 2.0 liter turbo four door. The Engine is a B207 Vin number is YS3FD49S631029231.
The ones you have provided would be awesome, but they are not for the model I have and are not really usable. For example the throttle body actuator on the car has 8 pins. The schematic on your email shows it as having 10 pins. The wiring color coding is completely different.
I do not have to have them but it will make what is going to be a tedious job tracing the wires back to the ECU just a little bit easier.
Would really appreciate anything you can come up with.
At this stage I can see that I have three of the eight wires that are hot going to the actuator. Running approximately five volts.

Cheers

Thanks Ken
Those schematics match the car. I do have the problem in that I see no way that the ECU plugs will split apart to reveal the connections within the plug. I can trace the wires by using a probe in the pin holes of the plug. But if I find I have a bad connection and there is no physical damage to the length of the wire (The wires all look like they are in good condition now I have unwrapped the insulating tape) I still have no way of re-soldering or repairing the joint that is within the plug. There must be a way as to have to replace that section of wiring harness for the sake of a loose or damaged plug connection seems an extreme measure.

Hi Ken
I've managed to sort the throttle body out. The motor that drives the spindle shaft that turns the butterfly was jammed shut for some reason. After spending a few hours chasing the wiring to from the throttle body motor back to the computer I determined the wires all had continuity and were connected to the ECU. I pulled out the throttle body and tested the connections to the motor. I could identify the pins because of the wiring diagram you sent. I then connected 5V to them and could only get a very slight movement on the butterfly.
But just to make sure this was the problem that was causing the engine not to run and I hadn't screwed the timing up when I put the engine back together (You start to doubt yourself when looking at the problem too long and the cams and cam gears have no timing marks on this engine so not easy to get right without the cam lock tools which I didn't have). As the throttle body was removed I made a plate to swivel over the throttle body opening on the inlet manifold and gave it a small opening so the engine could breathe and turned it over on the starter. It fired up and ran straight away although it was idling all over the place because the throttle body intake and and intake sensor could not be connected across the plate I had made. Anyway whilst I was doing all this I had the throttle body plugged into its plug and it was sitting on the valve cover.
After switching off the engine the throttle body butterfly had somehow done a reset and was working properly. Crazy. Bolted it back on and now it is working perfectly.
Next problem I have is the alternator is not charging the battery. Has a message come up on the dash. Put a volt meter on it and it definitely isn't charging checked all the plugs on the alternator and they are OK so I will have to pull it out and have a look. It might be the regulator diodes? Or I might need another one.

Cheers
