Long thread is P0340 code correct? Sounds like the camshaft sensor is either defective or not getting common, 5, and 12 volt power.
This link show the process to get at it,
For a 2005 but about the same for your 2001, ha, been about 40 years since neoprene timing belts been around, had my fill of them, belts seem to be okay, but the tensioner and idler pulleys have extremely limited lubrication, they seize and the belt breaks, heaven help you if you have an interference engine.
Had problems with Ford variable valve timing circuit, not easy to work on, sure a bunch of stuff on top of the valve cover that has to be removed. The good news about variable valve timing is that the exhaust valves close early leaving burnt fuel exhaust in the chamber.
This eliminates the need for that very troublesome EGR valve that was required ever since they removed lead from gas.
1930's vehicles did not need lead in fuel, was there to prevent detonation and also to reduce combustion chamber temperature from 2,600*F down to a more reasonable 2,000*F. 30's vehicles didn't need lead because the maximum compression ratio was more like 4:1. If your valve timing is slow or your EGR valve quits working will first burn up your exhaust valves then even burn holes in your pistons.
Another example where solving the lead in gas problem that for some passes the brain blood barrier makes them aggressive and stupid, doesn't this sound like our politicians? But also made engine far more complex.
Did not like the way that guy in that video tested the power plug, and one pin hitting ground could short out the power supply and god knows what else.
If you go this far to replace the cam shaft sensor, can also be corroded connectors, replace the timing belt as well, and definitely lubricate or replace the tensioner and if you have one an idler pulley ball bearings. If it says Made in China, pitch those as far as you can throw, caused more grief in the automotive industry then anything else. But maybe not with Japanese vehicles even made in the USA. Japan and China been hating each other since WW II.
88 Supra still has a timing belt, belt, and bearings were all made in the USA, but you really have to search to find them.
Virus culminates all the crap we got from China, they have no natural resources so make their bearings out of recycled throwaway tin cans
