So since i bought the car back in 2010 it had the constant DTC p1336 crank position sensor POS. , it never really was a problem in the past, since the engine ran good, it had a hard start but always started up every time, and other than the DTC i never had a problem. Well i decided to reseal the oil pan since i was passing it on to my son who is going away to college i figured if i do more work on it, the less he has to do to it when it comes time to fix it.

I resealed the oil pan and when i removed the pan low and behold i see my problem is the signal plate that is attached to the flywheel.

The kid i bought it from had the transmission and clutch replaced so when i got it the clutch was new so i had no reason to replace it , and if i had it long enough i am sure i would have had to replace it eventually. .

 

You can see the signal plate is damaged on the FW , i just wanted to share what i found just in case anyone has the same type of DTC and everything else checks out

 

And my beloved 2000 Maxima

 

As long as it got fixed, thats whats important. I knew it wasn't the ECU because i did all of the electrical checks according to the FSM so the only thing left that was not verified was the flywheel signal plate , which i found when i resealed the upper oil pan.
