Super problem Ford Focus

Hello, if I have scanned the car, it throws the significant codes:

P0553 - Address pressure switch (PSP) of the PSP PCM signal input sensor circuit is a continuous monitoring. The test fails when the signal is shortly with power. PSP Damaged Sensor
SIGN RTN In short circuit to
VREF power in short circuit to power
the signal of the PSP sensor short circuit to the
damaged PCM
The code indicates that the PSP sensor circuit is short -circuit with power.



P0340 - Camsus position (CMP) of the malfunction sensor circuit The test fails when the PCM can no longer detect the CMP sensor signal. CMP Open circuit
CMP Short circuit A GND

CMP

DTC PCM unit have recently been cleaned


force tool . maintenance. P2004 Admission Collector Runner Control Stuck Open - Bank 1, Failure Indicator Lamp (Mil) with Problem Diagnostic Code (DTC)




Tell me, what do I do, do I need to change the 2 sensors? The camshaft and the direction pressure?

Hello, I would cancel all the codes and check if any cable or connector or possibly any air depression hose has been discounted, check if the accounting works you, the P1000 code ignores you now now and focus on the codes I will say after the test.-

Who helps me want to change the external voltage regulator the one that has 4 IASF lines but the one I want to put is a nippopondenso of 6 lines, but this does not indicate which one can help me ..

greetings
