Crank sensor problems

juld0zer · 05-10-2014, 01:13 PM

thats really bizarre because the way the sensor is designed, it can only be secured in one position give or take a few degrees at most. and im
willing to bet that the tip of the sensor will produce the same signal irrespective of whether it is bolted in the intended position or glued in place rotated X degrees from the bolt hole

If I had to guess it would be a broken wire in the engine wiring harness. Why you ask? Because I have fixed several Nissan vehicles with this problem that would cause chronic codes to pop up. Good luck finding someone with the skill set to fix it.

You can get pretty cheap basic oscilloscopes these days that would help in this situation. Assuming everything electrically checks out you're left with a faulty ECU or mechanical fault, such as the reluctor device becoming loose or stretched timing chains

Has anyone solved this issue on their Z? My car is experiencing the same thing. Any insight would be helpful...I have replaced both the cam and crank sensors. Uhg... HELP!

I recently had a similar issue. My car only started with the cam sensor unplugged and drove around fine in limp mode. The dealership closest to me has repeatedly screwed me over, so I decided to repair the car myself.

The issue was that my timing was off quite a bit (-30* bank 1, -22* Bank 2). I had to use a snazzy Snap-On diag computer and some time. After a quick search, I discovered that my cam phasers were seized. I changed the cam phasers and set the timing back to spec (10hr job and those fu#^ers are expensive new). The service manual is also a huge help. Now the car starts right up, as it should. I hope this helps.
