Good afternoon,
What exactly have you tried? Google sometimes is not the best source of information.
I attached a description and possible issues.
Do you have a scan tool to read live data?

Circuit/System Description
The camshaft position (CMP) sensor correlates the crankshaft to camshaft position so that the engine control module (ECM) can determine which cylinder is ready to be fueled by an injector. As the camshaft rotates, the reluctor wheel interrupts a magnetic field produced by a magnet within the sensor and sends a signal to the ECM through the signal circuit. The CMP sensor circuits are directly connected to the ECM. The CMP sensor also determines which cylinder is misfiring. The CMP sensor circuits consist of the following:
An ignition voltage
A low reference
A CMP signal
Conditions for Running the DTC
The engine is running.
The DTC runs continuously when the above conditions are met.
Conditions for Setting the DTC
P0341
The ECM detects no transition of CMP signal between 25th and 33th CKP pulse and detects change in polarity.
P0342
The ECM detects no transition of CMP signal between 25th and 33th CKP pulse and detects no change in polarity.
Action Taken When the DTC Sets
DTC P0341 and P0342 are Type E DTCs.
Conditions for Clearing the DTC
DTC P0341 and P0342 are Type E DTCs.
Diagnostic Aids
The following conditions can also set the DTC:
Physical damage to the CMP sensor or the reluctor wheel.
Excessive play or looseness of the CMP sensor or the reluctor wheel.
Improper installation of the CMP sensor or the reluctor wheel.
Foreign material passing between the CMP sensor and the reluctor wheel.
Excessive air gap between the CMP sensor and the reluctor wheel.
