Crankshaft sensor i repleced the crankshaft sensor on my 02 altima because of this code p0335 and after replacement it came up with a new code after reseting the computer, code p0725 what can i do

6. CHECK CKP SENSOR (POS) INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT 1. Disconnect ECM harness connector. 2. Check harness continuity between ECM terminal 14 and CKP sensor (POS) terminal 2.continuity should exist. Refer to Wiring Diagram. 3. Also check harness for short to ground and short to power. OK or NG OK >> GO TO 7. NG >> Repair open circuit or short to ground or short to power in harness or connectors. 7. CHECK CRANKSHAFT POSITION SENSOR (POS) Refer to EC-326, "Component Inspection" . OK or NG OK >> GO TO 8. NG >> Replace crankshaft position sensor (POS). 8. CHECK GEAR TOOTH Visually check for chipping signal plate gear tooth. OK or NG OK >> GO TO 9. NG >> Replace the signal plate. 9. CHECK INTERMITTENT INCIDENT Refer to EC-147, "TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT" . >> INSPECTION END Component Inspection UBS002UJ CRANKSHAFT POSITION SENSOR (POS) 1. Loosen the fixing bolt of the sensor. 2. Disconnect crankshaft position sensor (POS) harness connector. 3. Remove the sensor. 4. Visually check the sensor for chipping.

is it a no crank or crank no start?
Possible causes for code P0335
- Faulty crankshaft position sensor
- Crankshaft position sensor harness is open or shorted
- Crankshaft position sensor circuit poor electrical connection
- Signal plate may be damage
- Starter motor may be faulty
- Starting system circuit
- Dead or weak battery

Hi Todd,here's a link on your code P0725,here's code P0335.Here's a link to your speed sensor.Here's the crankshaft position sensor.

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

Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer. Thank you for using Fixya, and have a nice day.

Did you do a crank relearn ? Could be a wiring issue , control module problem etc... Testing electrical circuit first , video's on youtube , all you would need is a DVOM - digital volt ohm meter . P0335 Kia Crankshaft Position Sensor Circuit c Replacing Crankshaft Position Sensor Code P0335

I need solution for this dtc p0335

If it has a code for loosing the crankshaft position sensor signal, I would certainly start looking at that before venturing into the fuel system. Cam and Crank sensors are a common failure item for Nissans of that era. Nissan actually redesigned the sensor and i think they performed a recall on some vehicles. They are fairly inexpensive and easy to replace. I believe they run about $40 each. Because most people don't have access to a powerful scanner or a digital storage oscilloscope to verify the failure I recommend replacing the cam and crank sensors at the same time.

P0335 is fault code for crankshaft position sensor

In the kit there are two sensor that look identical. The one for the crankshaft has a white paint mark on it near the bolt hole. Make sure that it is in the right location.
