Nissan Murano P0340 2005 Nissan Murano - Camshaft Position Sensor Circuit
Possible causes- Faulty Camshaft Position Sensor-
Camshaft Position Sensor harness is open or shorted- Camshaft Position Sensor circuit poor electrical connection- Faulty starter motor- Starting system circuit-
Dead (Weak) battery
P1701- Fuel trim

I would suggest replacing the camshaft position sensor. When the sensor fails it can cause changes in fuel system that the computer can detect. So I suspect once the camshaft sensor ivreplaced that the P1701 code will be gone.

It basicall means you got that camshaft a little bit out of sync.If it a twin cam or a singke overhead cam what it relates to is the position in relation to the crank both have sensors the crank moves the pistons up and down and the cam opens and closes the valves and in that car drives the distrubitor . So the spark along with the opening and closing of the valves is to early or to late. I know you dont eant to but remove the timing belt covers and turn the crank to TDC ( top dead center) look at your cam timing marks ill bet they aren't exactly where they should be. Line those up and erase those trouble codes and reset the check engine light youll be good to go

All ways, the camshaft position sensor signal sent to the ECM is intermittent

The Camshaft Position Sensor is an electronic device used in an engine to record the rate at which the camshaft is spinning. This information is used by the Powertrain Control Module (PCM) or Electronic Control Module(ECM) to control ignition and fuel injection. The camshaft position sensor senses the retraction of camshaft (intake) to identify a particular cylinder. The camshaft position sensor senses the piston position. The sensor system consists of a rotating part, typically a disc, as well as a static part, the actual sensor.

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. The change in the magnetic field cause the voltage from the sensor to change.

When the crankshaft position sensor (POS) system becomes inoperative, the camshaft position sensor provides various controls of engine parts instead, utilizing timing of cylinder identification signals.

Check thos DTC diagnostic and possible solutions about P0344 - Camshaft Position Sensor Circuit Intermittent

Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Lack/Loss of Power
- Engine Stall

Possible causes
- Harness or connectors (The sensor circuit is open or shorted)
- Camshaft position sensor may be faulty
- Camshaft (Intake) may be damage
- Starter motor may be faulty
- Starting system circuit
- Dead (Weak) battery

Possible solution
- Charge battery
- Repair harness or connector
- Replaced Camshaft Position Sensor.
Tech notes
- Sometimes and in some models, low battery voltage or a weak starter can can trigger a Camshaft Position Sensor code.


Hope this helps.

They may be right. I cannot find the part. here is what the manual says:

REMOVAL & INSTALLATION The camshaft position sensor is located inside the distributor. On some distributors, the camshaft position sensor is not serviceable (replacement parts may not be available separately). If the camshaft position sensor is serviceable, use the following procedure.

1. Remove the distributor cap and wires.
2. Remove the rotor.
3. Remove the camshaft position sensor cap.
4. Remove the camshaft position sensor mounting screws.
5. Carefully remove the camshaft position sensor.

To install:

1. Position the camshaft position sensor in the distributor and tighten the mounting screws securely.
2. Install the camshaft position sensor cap.
3. Install the rotor.
4. Install the distributor cap and wires.

The camshaft position sensor sends a signal to the PCM, powertrain control module. The PCM then determines spark plug firing. Could be the camshaft position sensor.

1996 is all I have
Camshaft Position (CMP) Sensor 3.0L (2V) Engine
The camshaft position sensor (CMP sensor) (12126):

• is a single Hall-effect magnetic switch activated by a single vane which is driven by the camshaft (6250).
• provides camshaft position information which is used by the ignition coil (12029) and the powertrain control module (PCM) (12A650) for fuel synchronization.

3.0L (4V) Engine
The camshaft position sensor (CMP sensor) (6B288) is:

• a variable reluctance sensor.
• triggered by the high-point mark on the LH exhaust camshaft sprocket (6256).

-----------------
3.0L (2V) Engine
SPECIAL SERVICE TOOL(S) REQUIRED Description Tool Number Syncro Positioning Tool T95T-12200-A
CAUTION: Prior to removal of the camshaft position sensor (CMP sensor) (12126), set cylinder No.1 to zero degrees top dead center (TDC) of compression stroke. Then note the position of the camshaft position sensor electrical connector. The installation procedure requires that the connector be located in the same position.
Removal

1. Disconnect battery ground cable. Refer to Section 14-01 .
   

1. Disconnect engine control sensor wiring connector from camshaft position sensor.
   

1. Remove camshaft position sensor retaining screws and camshaft position sensor from camshaft position sensor housing.
   

1. If removing camshaft position sensor housing from the cylinder block (6010), proceed with Removal Step 5. If not removing camshaft position sensor housing, proceed to installation Step 6.
   

1. Remove hold-down clamp (bolt and washer assembly).
   

1. Remove camshaft position sensor housing from cylinder block.
   

Installation

1. CAUTION: A special service tool such as Syncro Positioning Tool T95T-12200-A must be obtained prior to installation of the replacement camshaft position sensor. Failure to follow this procedure will result in improper camshaft position sensor alignment. This will result in the fuel system being out of time with the engine, possibly causing engine damage.
   Attach Syncro Positioning Tool T95T-12200-A as follows:
   
   1. Engage camshaft position sensor housing vane into the radial slot of the tool.
   1. Rotate tool on camshaft position sensor housing until tool boss engages notch in camshaft position sensor housing.

1. Pre-lubricate synchronizer gear with engine oil meeting Ford specification ESE-M2C123-A prior to assembly.
   

1. Install camshaft position sensor housing so that drive gear engagement occurs when arrow on locator tool is pointed approximately 75 degrees counterclockwise from the rear face of the cylinder block. This step will locate camshaft position sensor electrical connector in the pre-removal position.
   

1. Roatate Syncro Positioning Tool T95T-12200-A clockwise slightly. This will engage oil pump intermediate shaft. Push downward while adjusting Syncro Positioning Tool T95T-12200-A until the Syncro Gear engages the camshaft gear.
   

1. When synchronizer flange is fully seated against block, the installation tool should be facing counterclockwise of engine centerline approximately 33 to 45 degrees.
   

1. Install hold-down clamp (washer and bolt) and tighten bolt to 19-30 Nm (14-22 lb-ft).
   

1. Remove Syncro Positioning Tool T95T-12200-A.
   

1. CAUTION: If camshaft position sensor electrical connector is not positioned properly, DO NOT reposition the connector by rotating the camshaft position sensor housing. This will result in the fuel system being out of time with the engine, possibly causing engine damage. Remove the camshaft position sensor housing and repeat installation procedure, beginning with Step 1.
   Install camshaft position sensor and retaining screws. Tighten screws to 1.5-4.0 Nm (13-35 lb-in).
   

1. Connect engine control sensor wiring connector to camshaft position sensor.
   

1. Connect battery ground cable.
