Oil level and timing sensor codes

Scanned the vehicle, and got a p0011 code, which was surprising to me. A camshaft A advance code.
I did check the engine oil, it was so low, just on the L mark.
I intend to check the phaser, solenoid sensors on the timing chain cover, ...
- not typically related on the VK45DE engines
- you should still keep an eye on your oil level though. These engines are unforgiving when run low for extended periods of time.
- a little more likely, although not common. Remove the sensor, wipe off any grime on it and also check the cleanliness of the pickup on the VTC sprocket.
- most times, this ends up being a bad sensor. However, since I don't like spending money I don't have to, I favor cheap troubleshooting steps.
- switch the sensor from the left bank to the right bank and see if the P0011 code goes away and P0021 appears, which would indicate a bad sensor.
- if the code doesn't change despite relocating the sensor, then you can dig deeper.
Hi edboy! Dont know if i should create another thread, or just continue updating in here though.
Some updates on my car today:
1. Carried out continuity test on the power and ground wire harnesses on both the cam and crank sensors, and discovered that there seems to be short to power on the wires.
I did this test with the ECU unplugged, and each of the connectors tested. Surprising, i got the wires shorting to ground, which i think is absord.
How i understand testing for power on the power wires on the cam/crank to work is, ignition ON, with sensors unplugged, and probing the positive power wire on the connector harnesses with the positive probe of my meter and connecting the ground lead to ground or chassis.
The results should be battery power. But in my case, I'm getting positive battery power on the power and grounds points of the cam/crank sensors.
2. With the ignition OFF, i still keep getting battery voltage on the power and ground wire harnesses of the sensors.
There's also continuity of the power wire harnesses of the sensors to chassis, which is not supposed to be so.
I'm of the opinion that the power wire harnesses are not supposed to have continuity with ground/chassis, but only the ground wire harness side of the sensors that are supposed to have continuity with chassis?
The signal wires, don't have issues, cos they are not shorted from my tests.
PS: i think my hypothesis is that, because of the short to power or ground that I'm getting now, could be the reasons why the cam/crank sensors burned out probably, because from my tests today, it appears the sensor harnesses circuits, were always on HOT, so this may have destroyed my sensors, and not to cause the car to start, with the hardstart I'm experiencing?
Prelude to this has been, engine cranks for a LONG time, and it attempts to starts, as it starts, and rpm is at 1000, the engine shuts down.
When i checked for spark on one of the ignition coils, spark was not bright (hard to see), before it eventually totally went out.
