hi my check engine light goes on .

Question

i scan it and gave me two different codes (po340) (p0344) what do the codes mean ?

Answer 1

the codes are for Camshaft Position Sensor. If your battery and charging system are good replace the Camshaft Position Sensor. The codes are for bank 1 sensor but I would replace both bank 1 and 2 to avoid the problem which will come soon since they usually good out at the same time.
