As expensive as the parts are, I would only recommend changing what is faulty.

P0725 NISSAN - Engine Speed Signal

The P0725 Codes is triggered when TCM does not receive the engine speed signal from ECM.

The Engine Control Module (ECM) monitors the engine speed through the Crankshaft Position (CKP) sensor with the engine running, and send signal to the Transmission Control Module (TCM).

Symptoms:
- Engine Light ON (or Service Engine Soon Warning Light)

Possible causes:
- Open or shorted CKP sensor circuit condition
- Poor CKP sensor electrical connection
- Check communication error between the ECM and TCM
- Failed CKP Sensor

Possible solution:
Very common problem with Nissan vehicles, usually replacing the Crankshaft Position sensor takes care of the problem.

Recall Number: 07V527000 Dates Manufactured: JAN 2004 to OCT 2006 Number of Vehicles Affected: 653910 Date Owners Notified On: DEC 2007 ON CERTAIN PASSENGER VEHICLES EQUIPPED WITH A 2.5L ENGINE, THE CRANKSHAFT POSITION SENSOR CAN OVERHEAT CAUSING A BRIEF INTERRUPTION IN THE SIGNAL OUTPUT FROM THE SENSOR. Consequence of Defect:
IF THE INTERRUPTION IN THE SIGNAL FROM THE CRANKSHAFT POSITION SENSOR IS SO BRIEF THAT THE ELECTRONIC CONTROL MODULE (ECM) LOGIC DOES NOT HAVE TIME TO DIAGNOSE THE CONDITION, THE ENGINE MAY STOP RUNNING WITHOUT WARNING WHILE THE VEHICLE IS DRIVEN AT A LOW SPEED INCREASING THE RISK OF A CRASH. Corrective Action:
DEALERS WILL REPROGRAM THE ECM FREE OF CHARGE. CERTAIN MY 2006 ALTIMAS WHICH HAVE BEEN PREVIOUSLY REMEDIED UNDER RECALL CAMPAIGN 06V223 (NISSAN R0606) ARE NOT INCLUDED IN THIS RECALL SINCE THE REPROGRAMMING FOR 06V223 ALSO INCLUDED THIS REPROGRAMMING. THE RECALL BEGAN ON DECEMBER 31, 2007. OWNERS MAY CONTACT NISSAN AT 1-800-647-7261.

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.

A camshaft sensor can cause a no start situation, so can a bad coil, or ignition control modual. You need further testing done.
A speed sensor does not cause a no start, that I'm aware of.

Crankshaft and Camshaft Position Sensors Camshaft Position Sensor Engine timing is determined from the relationship between the crankshaft and camshaft. This relationship is maintained by a timing chain or timing belt. The Engine Management System does not control engine timing but it does monitor the relative position and speed of these shafts by monitoring signals generated by sensors. The Engine Management System (EMS) uses signals generated by the camshaft position sensor to synchronize fuel injection to the valve sequence and for the on-board diagnostic procedure for misfire detection. The EMS energizes the injector at or near the time the intake valve opens. For misfire diagnosis, the EMS compares the number of camshaft sensor reference pulses and the number of crankshaft position sensor reference pulses received. If the EMS receives an incorrect number of pulses Diagnostic Trouble Codes (DTC’s) should be stored in the EMS.
If the camshaft position sensor or circuit is faulty most engines will start. Some engine management systems will then default to a pre-programmed injector firing sequence. All injectors may be energized simultaneously or all of the injectors on one bank may be energized at the same time. If the CMP data is required for misfire detection and reliable CMP data is not present misfire detection would probably be suspended.
Related Symptoms The following symptoms can be caused by an intermittent wiring connection or faulty signal to the EMS:

• Extended crank time with a cold engine
• Intermittent rough running
• Unstable idle
• Bucking
• Hesitation
• Stumble
• Chuggle
• Poor fuel economy
• Stalling on acceleration

Crankshaft Position Sensor Engine speed is a very important input to the Engine Management System (EMS). Crankshaft speed and position are the basis for many calculations made by the computer. Crankshaft position values are transmitted to the computer by pickup coils also known as Permanent Magnet (P/M) generators, hall-effect sensors or optical sensors. The Crankshaft Position Sensor (CKP) also known as engine speed sensor is located in close proximity to the crankshaft.
In addition the EMS uses minute variations in the CKP sensor data to determine engine misfire. The EMS uses this information in conjunction with the camshaft position sensor to perform misfire diagnostics.
Related Symptoms: No Start/Intermittent Start Condition – Can be caused by a faulty crankshaft position sensor due to loose connections, bad grounds, high resistance in the circuit, or opens in the circuit

the 2.5 altima's had a recall on that problem about 2-3 years ago. Go to edmunds or progressive find the recall letter and the dealer will fix it free. well here you go:

Summary: ON CERTAIN PASSENGER VEHICLES EQUIPPED WITH A 2.5L ENGINE, THE CRANKSHAFT POSITION SENSOR CAN OVERHEAT CAUSING A BRIEF INTERRUPTION IN THE SIGNAL OUTPUT FROM THE SENSOR.

Consequence: IF THE INTERRUPTION IN THE SIGNAL FROM THE CRANKSHAFT POSITION SENSOR IS SO BRIEF THAT THE ELECTRONIC CONTROL MODULE (ECM) LOGIC DOES NOT HAVE TIME TO DIAGNOSE THE CONDITION, THE ENGINE MAY STOP RUNNING WITHOUT WARNING WHILE THE VEHICLE IS DRIVEN AT A LOW SPEED INCREASING THE RISK OF A CRASH.

Remedy: DEALERS WILL REPROGRAM THE ECM FREE OF CHARGE.

Potential Units Affected: 653910

Notes: NISSAN NORTH AMERICA, INC.

Probably sensors! I have already replaced the crankshaft positioning sensor once, nissan replaced it once under recall and now it is bad again! Plus my speed sensor is bad too! Go to any part store and get diagnostic test ran, it will tell what sensors are bad.
