Golf IV 1.4 AKQ - Sensor error G28, fires after a long shooting.

Question

Generally, I have a problem with the error 00513 engine speed sensor G28 03-00 No signal.
I understand that it is about the shaft sensor, the sensor mentioned, the beam checked.
There is nothing disturbing about ECU.
If I give the signal from the generator in parameters, should I see the engine speed? Or is there a block corresponding to the value from the input of this sensor?

I had a similar case, replacing the sensor did nothing, helped to grip the sensor mounting so that it went deeper into the gearbox - but this solution lasted 3 months, later it was necessary to remove the gearbox and replace: sealing collar with ring impulse transmitter and auto rides.

This is how it looks:

The sensor is easy to check:
sensor description
1 + 5V
2 signal
3 GND

With a 5V resistor in series LED to Pin No. 2, as you turn the starter it has a LED blink.

Yes
The symptom is as if this lace has degaussed itself.
There was no way to magnetize. I was already combining the neodymium magnet with a sensor socket and turning the starter without candles, but there is very little space

Well ok, but if it's the fault of the collar, I understand that despite the new sensor the diode will not show anything like that? and then only replacing the collar with the transmitter?
Returning to the ECU how to check if the ECU is functional, having them on the table without any accessories?

kortyleski · Answer

On the table, what about immo? But you can fasten the power supply, tester and generator. The revolutions should be visible.

spinacz · Answer

Immo emulator and the error of the blocked controller disappears, ok tomorrow generator podepne.

Added after 34 [minutes]:

Ok, I connect the generator and the lime, I can not see the rotations or when I give a signal to the shaft sensor or to the shaft sensor.
I do not have cars in front of me to check if the computer can see the speed when it starts in safe mode.
The question is still regarding the lace from which the shaft sensor reads or are there all the teeth are the same whether a window is made eg the lack of two teeth?

Added after 8 [minutes]:

I am surprised that the error pops up immediately after switching on the power. There is no reaction, i.e. a change in error when I make a permanent entry with +5 or mass.

panstalin2 · Answer

There is a break for 2 teeth in the crown at the sensor. Attach the sensor to the Led Diada and wave the magnetized screwdriver in front of it - as an efficient sensor blinks.

spinacz · Answer

And how will it be the fault of the lace I understand that the symptom will also be a lack of blinking diode?

kortyleski · Answer

buy it. Maybe the helm is released ...

panstalin2 · Answer

And comes to the 5 V sensor after ignition? There is some resistance between pin no. 2 and GND in the plug from the sensor? Check whether it has a transition from the controller to the sensor.

spinacz · Answer

5V, the beam ok, the rudder on the table does not react to either a short to ground or power supply, the error does not change. I also suspect the driver.

panstalin2 · Answer

From the sensor the middle pin according to pulses makes mass through npn.

spinacz · Answer

Is the mass or impulse + 5V given to the input of the helm? Added after 26 [minutes]: Colleagues, or how will the transfer in this ECU eeprom be immo shifted?

panstalin2 · Answer

The middle pin sensor massages to ground. You must have the ECU with the key from the ignition - just immo put it from the key to the old key.

spinacz · Answer

What are you saying nonsense? Immo put only the stone from the key? And pairing ecu with clocks? And pairing the pit with clocks? In the same way, this impulse is impulses to the 5V mass of a square wave.

spinacz · Answer

I close the subject, however, the ring on the sealer does not give a signal, the ECUs are replaced, the sensors are checked, the error is still, however, the ECU does not immediately see the mistake of the previous one just after the filming.

spinacz · Answer

Replacing the transmission ring has helped.
