I’ve been having this issue with my crank sensor. Car has new hitachi cam sensors and maf and a new denso magnetic crank sensor. I’ve replaced it twice to no change. Car runs fine but had a acceleration issues 3rd gear and up. My lower O2 sensors aren’t connected and the wires are hanging. Today I got a new code after my car went into full limp mode. I reset the ECU with the pedal dance and car got out of limp mode and I could make it to work. I only got the power supply code when the car went into limp mode it’s gone after the ECU reset. My question is could the O2 wires be shorting out the crank sensor circuit. I plan on testing it all with a reader today after work. I’m just looking for more insight on the true cause or if any else happen to have the same issue or not.

 

I'd swap out that Denso crank sensor for a Hitachi one. Also inspect the harness to make sure it's not damaged.

 

I had a Hitachi one in before the denso but it was a voltage issue to the sensor I fixed it now.
