Hello everyone.

A few months ago í posted error log about my 2016 2.2D skyactive CX-5

Since then I have replaced the PCM, engine wiring harness (Only the big connection), tested new pair of injectors, replaced fuel filter and MAF sensor. All without any luck. I still live by the P2150 error. - - Fuel Injector Group B Supply Voltage Circuit Low. COM 2 ground short Ground short upstream of cylinders no. 2, 3 injector circuit (So injectors on cyl 2&3 do not get any feed from the PCM)

Most sensors have been checked with oscilloscope, crank showing perfect signal.

Here is the error log. Is it time to scrap the car or is there a magic solution.............

Thank you for taking time to go over this error log

 

Anyone that might have an idea of what could be causing this error?

 

Has it had any accident damage or repairs carried out in the previous 6 months?

 

No accident. But previous owner said that petrol went through the system when he accidentally filled with petrol but not diesel.

 

Has the fuel rail pressure been tested against spec? Petrol thru the high pressure pump usually ends in disaster.

 

Yes full pressure there.

What is weird that there is electrical error, not mechanical.
