Default 2005 Freestar P0340 code and hesitation

I had a squealing sound which I thought was a belt issue but turned out to be the Cam synchronizer. I replaced this part (it came with a new sensor as well) and then the van spit out the P0340 code. So far I have replaced the cam sync/TPS and cleaned the mass air flow sensor. The van runs fine but on acceleration at around 40 kmh and 100kmh it starts to bog down and lose power. I have cleared the code and it came back with the same P0340 code. Is there any way to tell if the sensor that cam with the sync is faulty?
