Hi

The crankshaft position sensor (POS) is located on the cylinder
block rear housing facing the gear teeth (cogs) of the signal plate at
the end of the crankshaft. It detects the fluctuation of the engine rev-olution.
The sensor consists of a permanent magnet and Hall IC.
When the engine is running, the high and low parts of the teeth
cause the gap with the sensor to change.
The changing gap causes the magnetic field near the sensor to
change.
Due to the changing magnetic field, the voltage from the sensor
changes.
The ECM receives the voltage signal and detects the fluctuation .
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 10.5V with igni-tion
switch ON.

The sensor is right by the passanger side drive shaft, where it goes into the transmission. Its right above the shaft. Single black connector with 3 wires coming out of it. Good luck changing it. Those are pretty tough to replace. I replace them from the top.

Replaced camshaft and crankshaft position sensors in my 2005 altima also the o2 seneor car still will not run. error code 335 What else could be the problem?


DTC P0335 - Crankshaft Position Sensor A Circuit Malfunction
The crankshaft position sensor (CKP) measures crankshaft location and relays this information to the PCM (Powertrain Control Module). Depending on the vehicle, the PCM uses this crankshaft position information to time the spark properly or on some systems it is only for misfire detection and does not control spark timing. The CKP sensor is stationary and works in harmony with a reluctor ring (or toothed ring) that is attached to the crankshaft. As this reluctor ring passes in front of the CKP sensor, the magnetic field created by the CKP sensor is interrupted and this creates a square wave voltage signal that the PCM interprets as crankshaft position. If the PCM detects that there are no crankshaft pulses or if it sees a problem with the pulses on the output circuit, P0335 will set.

A P0335 "check engine light" code could be caused by:
Damaged CKP sensor connector
Damaged reluctor ring (missing teeth or not turning due to sheared-off keyway)
Sensor output open
Sensor output shorted to ground
Sensor output shorted to voltage
Failed crank sensor
Broken timing belt
Failed PCM

Where is the crankshaft and camshaft sensor located?


Here's some pics of my 2003 Altima Crankshaft Sensor. Often mistaken by the Camshaft Sensor because both are identical sensors. They are each located in different locations. I've seen diagrams with the WRONG labeling. Again, this is so confusing for even a mechanic to understand because both sensors carry the same part number which is rare. http://x.nissanhelp.com/forums/members/digitaldxing-albums-2003-nissan-altima-crankshaft-position-sensor-picture331-2003-nissan-altima-crankshaft-position-sensor.html

Where crank shaft and camshaft?


The camshaft position sensor is located on the timing cover, near the top of the motor. The crankshaft position sensor is located on the same timing cover near the crankshaft. Just a side note, more than likely the crankshaft position is your issue and it's under a recall from Nissan and they will replace it for free.

CANNOT FIND THE CRANKSHAFT POSITION SENSOR


cerebral_eni: The crank position sensor is located at the back of the engine block just below the cylinder head. It actually projects into the bell housing and reads the teeth on the flywheel where it references TDC for #1 cyl and RPM's of the crank. It's a "Hall effects generator". Unless you are into electronics and have a lab scope to look for a square wave pattern, I will continue with my other input.
Nissan has a recall campaign on the crank angle sensors.
The campaign # is 07V527000:ECM update for stalling;
NHTSA07V527000 NOV 07,
The symptom was brief malfunction of sensor causing the engine to quit running which could potentially put the vehicle at risk for a collision. The sensors would ultimately fail. There was also a voluntary recall on the reprogramming of the ECM's due to stalling problems. TSB# NTB07-081, Campaign ID#R0712
I hope this information is of some assistance to you. You may be able you get your car repaired under warranty! Good Luck!
