Help with Camaro 2012 3.6 LTE- CHECK ENGINE LIGHT, errors - p0018, p0021, p0346
I have a Chevrolet Camaro 2012 and I have three error codes - p0018, p0021, p0346.
It appeared 2 years ago after I swapped engine it appeared immediately and I took 2 years and a lot of money and I still can't fix it.
Recently trying my last- I have changed ECU and programmed it, all 4 camshaft sensors, crankshaft sensor and all 4 oil valve solenoids and the issue was not fixed. It might be wiring issue as my wires look bad. Do you think I need to change engine wiringharness? It's a hard job and I want to know for sure. Thank you

I hope you haven't changed your wiring harness!
All 3 of your DTCs are pointing to a Bank 2 Intake camshaft timing issue. They are all essentially saying that yes there is a valid camshaft position signal but it's not where it should be. There are different faults that would set to say if you had a wiring / circuit issue.
The two possibilities I could see are the Bank 2 Intake cam being out of time or the cam actuator being faulty (the actual gear at the end of the camshaft) But either way it is pointing to a mechanical problem rather than electrical. First thing I would do is check the timing on all of the cams to compare.

That consists of an oil control valve (OCV), also called a solenoid valve and other components. This source says it best: The camshaft position (CMP) actuator is controlled by the powertrain control module (PCM) through a high control circuit and a low reference circuit. The high control circuit carries a 12 volt pulse width modulated (PWM) signal from the PCM to the CMP actuator solenoid in order to control the amount of engine oil flow to the cam phaser. The low reference circuit is used as a return circuit. The PCM has the ability to monitor the functionality of the high control and the low reference circuit. If the PCM detects an open, a short to ground, or a short to voltage, DTC P0013 sets. The "B" camshaft refers to the exhaust, right, or rear camshaft (looking at the engine from the drivers seat). Bank 1 refers to the side of the engine that contains cylinder # 1
