p0434 is an o2 sensor code (P0434 - Heated Catalyst Temperature Below Threshold Bank 2) i will assume you mean p0340
my p0340 was caused by a bad alternator voltage regulator/diode. this caused radio frequency interference that disrupted the cam sensor signal. i rebuilt my alternator and problem was solved. you could try having a parts store run a test on the alternator to see if it is good or not.
