I have a equinox 2015 with the 2.4 liter flex engine. I just recently had the engine overhauled as it snapped a connecting rod. Well everything is brand new now. I got the code of P228D which says it is fuel pressure/sensor/regulator. I replaced it. Im getting the same code all over again. The timing is correct as it has been re-checked 5 times. I replaced the crankshaft positioning sensor, the camshaft sensors on both sides of the cylinder head, the intake and exhaust solenoid sensors. Now. I still get the same code! Im totally stuck here and really need some help . Also Im getting correlation code from sensor B bank 1.. Please. Any ideas or input on this matter would be so greatly appreciated. Im stuck guys. And this car is breaking my wallet fast.

 

Could be you have a bad MAP "manifold absolute pressure", not the MAF.(mass airflow sensor) They don't go out often, but like anything, they can go south.

 

I will replace that too now that you mentioned it and I no exactly what that is. I will check into new tone rings today also. The crankshaft tone ring was good ans I replaced the crankshaft also when having the engine totally overhauled. . Yes, thank you for your idea! Could be a simple fix and save me lots of time and money too. Really Thank You! If this fixes the issue, I will repost that it was issue. When I get replacement. Again I appreciate all input here. Thank You!
