Does anyone know what the specs are for a good crank position sensor. Im doing and ohms/resistance test on mine and prong 1-2 and 1-3 are reading 690-704 but 2-3 is at 02-03. Sorry if im explaining this wrong. I have 11-12 volts going to the sensor so i pulled and it and did this resistance test. Thanks for any help guys! I have tried to look everywhere online for specs or someone explaining in detail what to do, but i have found nothing.

 

Its not as easy as testing resistance between pins. You need to put a supply voltage on the correct pin (I think it’s 12volts, might be 5volts) ground the ground pin, put a volt meter on the sensor pin and ground and then swipe a piece of metal across it and you should see a voltage change on the volt meter.

Why are you questioning your Crank Sensor?

 

I'm testing it cause my car is hard to start, takes like 12 minutes sometimes for it to start. I have replaced the sensor and made no difference, so i reinstalled my old sensor and now i have a P0335/ crank sensor CEL. I have tested the voltage to the sensor, I was advised to ohm test the sensor itself out of the car.

 

Sounds good …

What brand of sensor did you put in the car? What year is your z?

You likely have a bad cam shaft sensor and/or a bad crank shaft sensor…It is wise to replace all three sensors and only replace them with OEM Nissan sensors bought from the dealership or Hitachi Brand from a TRUSTED local autoparts store. Dont buy them online as many distributors say that they are OEM or hitachi and they are really not.

Clean your mass air flow sensor too.

I think if you replace all three sensors and clean your MAF your starting issues will go away.

inspect your wire harnesses too … make sure you dont have any broken/damaged/compromised wires in any of the connectors.

 

Will do, its got new OEM cam sensors, I bought a hitachi crank sensor from Autozone but it made no diff and returned it. That's why Im testing the crank sensor, from Nissan it's 150 for the crank sensor with no option to return if not the issue lol so I would like to be certain it's the sensor, and not find out the hard way it's something to do with the wiring.

 

Good good … yea, alot of people put non OEM / non hitachi and they shoot themselves in the foot.

I typically buy mine from Advance Auto Parts and use their online promo codes and get them for $60 to $70 each (sometimes shipped to my place).

To be honest, you are going to replace the sensors at some point in time … you might as-well put new sensors in the car and check that off the list.

Depending on how in-depth you want to get with your car - you may realize how significant the crank shaft and cam shaft position sensors are to the optimal running of the engine. I think I have around 68k miles on my z and I’ve probably replaced the cam shaft position sensors a dozen times … albeit, sometimes arbitary if I am going to an race event / track day or going to the dyno to tune. It’s just the cost of owning a performance car.
