P1336- crank sensor replaced, and vibration continues

[_evilive_]

Hi all, my 1999 QX4 has a engine vibration and the check engine light was on, a code P1336 was shown- it says "crank position sensor" malfunctions. Last weekend it was replaced, and the engine runs smoothly for only one night. however next morning the P1336 comes back.

I would like to know if any one meets this before? Or some expert might be able to talk about it?

Thank you!

maybe the new sensor went faulty?

Did you replace the sensor yourself, or have a shop do it? If you consider yourself able to do this kind of thing, you should be able to do a procedure to test the sensor. I'll see if I can track it down in the FSM.
