[quote=”rolando80″ post=64004]Can that be the problem causing this issue..

yes, that is the problem. or the wiring/connector. way less likely the computer or damaged “reluctor ring” on the crankshaft or whatever. and it’s probly not the timing belt (since your car has a timing chain.) look for oil in the connector maybe, too. idk.

get your hands on a manual and a multimeter and you can at least test the resistance of the sensor. also, if replacing, consider purchasing from the junk yard or an online parts store like Rockauto. cheaper that way probably.

i think to test the resistance you just test each combo or pairs of pins in the connector (1 and 2, 2 and 3, 1 and 3) and you’re looking for any resistance other than zero or infinite on each pair. so a reading of zero or infinite would indicate need for replacement. confirm that with a manual and/or use the same test on a new one.

looks like polarity might matter when checking resistance.

and here’s a cheap multimeter if you dont have one

sensor is on the front side of the motor, maybe in the oil pan. idk. 3 wire connector. one little bolt holding it on. just remove bolt and pull sensor firmly. not sure if oil will drain tho. might be good time to change oil. do not over tighten and snap that bolt off when reinstalling!

[quote=”college man” post=64012]also replace the cam position sensor.which is recommended
by Nissan. [/quote]

why would you replace the cam position sensor? and where does Nissan recommend that?

i see
