I’ve got a p1336 code otherwise known as a 0905 crank position sensor (POS)
This is the sensor on the tranny bell housing.

The car runs fine, and starts up fine (with the exception that I believe I have a leaking injector and am losing fuel pressure when the car is turned off....another issue, but not related and im not even positive that this is true). I have no issues with it running.

Here is what I have done:

1. SEARCHED....
2. Checked and followed the FSM
3. Checked the continuity in accordance with the FSM
4. Checked the POS sensor.....replaced (didn’t solve and was never busted anyone need a good used one?)
5. Re arranged harness at ECU according to this Technical Service Bulletin http://www.jatan.net/tsbs/041938.pdf btw…this is a pain in the #$@

The result....none of the above have fixed the issue.

I HAVE:

1. Reset the ecu each time and every time the code comes back THE THIRD TIME THE CAR IS STARTED after each reset.
2. Turned the screw all the way back to its proper location.
3. tested to see what would happen if the sensor was unplugged....the car doesn’t start at all.

The only thing left that I can think of is the flywheel sensor ring itself....

Does anyone see anything I have overlooked? And if it is the POS ring on the flywheel, will the sensor ring that is on the flex plate of an auto tranny work? I know the manual = bolt on sensor ring and auto/flexplate = rivet on. I know the rivet have to be drilled off to remove it, but is it still possible to bolt this to the manual flywheel? - edit i found out this would not work.

 

bump....from page 7 with no replies...

 

raised from the dead... I was wondering if one of my injectors is leaking and making the engine not want to start the first time would cause the 1336 code because it isnt turning over at the correct RPM. What do you think? I dont know if I have a leaking injector...but its the only other thing i can think of that would cause it not to start the first time.

 

alittle help guys.....i have searched and still no avail. Do you think it could and anything to do with the fact that i have to turn my car over twice before it starts?

 

Yes, and I know that you know this, the fsm is pretty clear on this, short of inspecting all of the teeth on the sensor ring you've done everything else. You could always remove the sensor and have an assistant turn the crank by hand while you shine a light and make sure you don't have any issues going on with the ring.

 

fwi....the problem here was that part of the through out bearing broke off (the clip that holds it to the fork that the slave cylinder press against) and it was flying around inside the bell housing. it bent one of the teeth on the timing ring. thats what was making the code go off.

 

ouch same ring that i changed a few weeks ago hard to find got to remove the tranny because it goes bolted to the flywheel good luck

there is a place called king nissan in CA that sell it for around $70 don't have the link right now

 

I do have a stock flywheel for sale with the ring gear in good condition. PM me if you're interested.

 

I'm sure he probably bent it back, it's not that hard to do in most cases. Just out of curiousity, did you find this by taking my advice of shining a light w/sensor removed while an assistant turned the crank?

 

if it were like mine that got 6 teeth stripped i don't think so

 

woah how come i had that p1336 come up and its an o2 sensor
