Dodge Neon 2.0 SOHC P0340 Fix

i recently worked on a 2005 Dodge Neon 2.0 Sohc. the car had come from an tow auction that my friend devin had purchased it was a non running car at that time no key. so after getting a key made for the car it started right up without a problem. we had noticed that someone had installed a new clutch. they had also replaced the starter, they also had installed a new timing belt.  the car would run for about 2 minutes then the check engine light would come on. the only code was P0340 Camshaft intermittent signal. i replaced the Camshaft sensor and it didnt fix the problem. i proceed to check wiring from the ecu to all of the engine sensors there was a problem i also replaced the cam magnet n that did not fix the problem i tired all the fixes that are present thru the forums for neon's n pt cruisers and stratus's. i decided to check mechanical timing. i rented a Harmonic balancer puller, pulled the harmonic balancer off. removed the engine mount plate aka front plate. removed the 2 bolts at the bottom of the timing belt cover. removing the timing belt cover i noticed something was wrong, i have worked on a lot of these 2.0 sohc engines. i hand cranked the engine to TDC on the crank shaft n thats when i noticed the camshaft sprocket was 2 teeth advanced. loosened the timing belt tension-er.  after retiming the engine, i put the harmonic balancer back on and started the engine. after about 2 minutes i decided to check for codes with my scanner. the P0340 code was finally gone no more random bogging or stalling past 2300 Rpm. so if you have recently performed a timing belt replacement and this code comes up almost instantly recheck your timing marks to confirm nothing moved.
