Will not start with p0340 code.

Question

Replaced head gaskets on 2004 Mazda 6s 3.0 v6. Now will not start with p0340 code. Replaced both cam sensors and timing chains w/ tensioners. Any ideas ?

Answer 1

The left and right side camshaft timing gear are the same for either side, but the camshaft is different from left to right, you may have to check the camshaft being in its proper place for the left or the right. Plus if there is a no start a camshaft code is always set
