Before you replace a part you may or may not need . Why ? What code ? Does the vehicle run ? There has been a lot of confusion on these vehicles with variable valve timing , mixing up cam sensors with camshaft actuators
DTC P0008: Engine Position System Performance Bank 1

DTC P0009: Engine Position System Performance Bank 2
The presence of DTCs P0008 and P0009 along with P0016, P0017, P0018, and P0019 indicates a possible condition with the primary timing chain and the alignment between both intermediate sprockets and the crankshaft. Or, the crankshaft reluctor wheel has moved and is no longer referenced to top dead center (TDC).

?€¢
Observe the scan tool CMP Desired, Actual, and Angle Variance parameters before a DTC sets. This may help to isolate whether a condition is specific to one camshaft, one bank, or caused by a condition with the primary crankshaft timing.

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.

This information is used by the Engine 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.

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.

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.
