Just to make sure, you are using the tool to align the crank pulley as well correct? 303-1550

Yes I used that tool as well. I double checked the timing and everything looks good.

Something must be off with the timing. Do you have a scope, if so attach a picture of the waveform. I assume you are using the timing tools for this engine?

Yes I’m using the correct timing tools to set the timing. I’m going to check the waveform today and send a picture.

Just a wild guess but is it possible that the sensors are plugged in back wards. If it sets the codes right away maybe why.

What do the timing PIDS indicate?

Eddy, the cmp/reluctor pulses should have 2 wider pulses and 2 narrow pulses.

Great job posting the waveforms. As Ray said you can see something is not right on what should be the 2nd narrow pulse. My next move would be to look at the reluctor for damage.

By “as soon as vehicle is turned on” do you mean as soon as the key is turned to the run position and the engine is off, or do you mean as soon as the engine starts? P0340: Camshaft Position Sensor A Circuit Bank 1 or Single Sensor P0344: Camshaft Position Sensor A Circuit Intermittent Bank 1 or Single Sensor Both codes are loss of signal, intermittent or shorted from camshaft sensor A You…

Are you leaving the crank pulley bolt loose when you pull the pin on the tensioner? The crank pulley must be allowed to spin when timing belt tensioner is released

I want to thank everyone for their help. I didn’t get a chance to reply to everyone but I tried everything that was suggested. I verified the timing one more time and it was good. The last thing i did was switch the bank 1 and bank 2 Cmp connectors and got a code for bank 2. We replaced the intake camshaft and that solved the problem.
