I have the P0335 code on 02 maxima for the crank sensor and Ive been reading online about replacing the cam sensors whenever you replace the crank sensor. Is this necessary? Also when I have been looking online at the cam sensors I see some that are angled and some that are straight, is one for bank 1 and the other for bank 2? My biggest concern is finding out where the crank sensor is located. Ive looked online and cannot find good pictures of where it is located.
