i have been going crazy trying to fix this car! got 3 codes (po334,335,660) replaced crank sensor but got same 3 codes right back. please help. thanx

 

PLEASE don't post in multiple sections with the same question. Give us some time to answer.

P0334 is knock sensor
P0335 is crank sensor
P0660 is intake manifold tuning valve control circuit open bank 1

So since you already did the crank sensor (is it installed PROPERLY? adjusted as necessary?) time to look at the knock sensor and figure out what that last code means. Now it took me a total of 1 minute to actually find the info I've just posted. Searches are wonderful tools.

 

sorry ,first time posting, wont happen again.
