This is my first post so hopefully I am in the proper area. This post was in another group but may have been in the wrong place, sorry if duplicated.
My 2007 G35 VQ35 (HR) is my everyday driver that is not drivable at this time. Story is, I started the engine and when I put it into drive,,, it died and would not start again. The cadence of the cranking sounds a little
off. From reading online, some are saying try cam and or crank position sensors. My question is, how many part numbers are out there for the cam sensors? Is the bank A one number and bank B
another number? Are they the same number for both banks? Looking at parts online I see HR & DE sometimes use the same, I see HR only or DE only, I see left side. I can type in description and get only one number, so I'm getting confused on the information that I find and don't find. I want to get the correct parts the first time. So finally, I thought that I could come here on the forum and show my ignorance and get answers.
Thanks

 

VQ35HR only get Denso for cam and crank positions sensors. They are expensive but are the best for the HR engine. Here, check out my thread about Long and rough warm or hot restarts post #27 is where i start to measure the Hitachi and Denso sensors. If you look at the beginning of this thread, you'll see what i've replaced AFTER i've replaced my cam sensors with those Hitachi ones from RockAuto. So, take a chance OR do it once, the right way..

The VQ35HR has 1 crank sensor part# 23731-JA10C and 4 camshaft sensors part# 23731-JA11B. Buy from the dealer to avoid fake ones.
