Re: Opel Zafira B 2006 Z22YH cam crank waveform

Hi.
Here's for you.
Quite a high mileage car.
But the engine is working fine.
No error.
The vacuum in the receiver is fine.

Re: 2013 2.5 Hilux injector comparison on frp

I have done that but cant see a deviation If we are talking about the fuel equipment DENSO, namely it is used on TOYOTA, the deviation of the fuel pressure when the injector is triggered at idle is almost invisible. You can see the pressure deviation only when the rpm increases when the SCV valve c...

what discrepancies I should look for in future?
Hi.
You should notice all the details.
Sometimes some subtleties are not visible in the scanner log.
The main thing is the value of pressure and time.

Re: Merc E220 bluetec 2015

Hi. Only-the opinion. It is possible, that without SCN coding, you will not finish the repair. There were cases-similar to Yours. But they belonged to the early releases of models with the SCR system. The problems with SCR after repair, could only be solved by SCN coding the ECU. If you see the curr...

Re: M278 long crank position of intake camshaft fault

Hello. If the camshaft disc has a backlash on the shaft, then this would be seen on the waveform or in the scanner values. In the waveform shown - there is no backlash. Perhaps this can be seen on the oscillogram of the starter scroll. M278 VS M278.PNG The parameters of the camshaft base position sh...

Re: CAN Bus wave pattern for 2007 Jeep GC WK?

What is the source of your information? Can you share a link? All this is in the schematic diagrams (MOD). Perhaps they have inaccuracies. But this does not change the meaning, there is no activity on the CAN DIAGNOSTIC line in the absence of the scanner-gateway dialog. On the CHEVI SUB connector, ...

Re: CAN Bus wave pattern for 2007 Jeep GC WK?

There is a fundamental difference in the connection on the diagnostic connector DLC 16. DLC 16 Chevrolet: 6 pin - high speed GM Lan BUS+ 14 pin - high spe...

Re: BMW 116i N45B16 Crank Sensor Signal

Support opinion.
The crankshaft sensor signal on this engine should look different.
Like this example.
If Your question is about the shape of the signal at high RPM,the tooth signal really becomes triangular.
