Hi.
.
There is an error on the diagram.
The correct scheme looks different.
Here is the manual (DTC P0400) :

Hi.
The main problem is related to the faulty signal of the crankshaft sensor.
This, in turn, is due to a damaged signal disk.
The reduced voltage on the camshaft sensor is due to the fact that when the starter is running, the on-board voltage has decreased.

Here is 5FS, which starts normally.

Just an opinion. There may be not one, but several malfunctions. One - is the wrong ratio of crankshaft - camshafts. This can be argued - based on the errors that are available immediately after starting the engine. The second - is the lack of engine start. . The easiest way to determine this, is to...

After starting the engine, a PWM signal appears on the control valve, that is different from the control PWM = 10%. When controlling approximately about PWM = 40%, a shift towards late is obtained. The shaft occupies the same position equal to 110 degrees on the scanner. But this is subject to the n...

Hello. . If there are serious errors in the engine management system, the velvetronic system is turned off. The electronic throttle system is activated. The engine starts working with discharge in the intake manifold. That's why there is a difference in compression. . Since both phase regulators hav...

Hello.
Here You go :

Hello.
The duration of the injector pulse after entering the idle mode is clearly underestimated .
Possible cause - leaky intake.
Or - incorrect readings of the air flow meter.
That's about how it should be with a hot start :

Hello.
The code P1174 is not related to the crankshaft sensor - camshaft sensor pair.
The code is related to the need to reset the ECU adaptations.
Try resetting adaptations with the scanner.
