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.

I'm sorry but when dealing with these problems your best bet is to take your vehicle to a qualified repair shop , I have never see a DIY'ER correct the problem with these , an in the end always end up taking it to the dealer .

P0014 Chevrolet Description
The Camshaft Position (CMP) actuator is attached to each camshaft and is hydraulically operated in order to change the angle of the camshaft relative to Crankshaft Position (CKP). The CMP actuator solenoid is controlled by the control module. The control module sends a pulse width modulated 12-volt signal to a CMP actuator solenoid. The solenoid controls the amount of engine oil flow to a CMP actuator. The CMP actuator can change the camshaft angle a maximum of 25 degrees. The control module increases the pulse width to accomplish the desired camshaft operation
Possible causes
- Dirty Oil
- Low engine oil level
- Faulty Exhaust Camshaft Position Actuator Solenoid
- Exhaust Camshaft Position Actuator Solenoid harness is open or shorted
- Exhaust Camshaft Position Actuator Solenoid circuit poor electrical connection
- Faulty Engine Control Module (ECM)
There may be a service bulletin for your vehicle.

Exhaust Camshaft Position System Performance Possible causes
- Dirty Oil
- Low engine oil level
- Faulty Exhaust Camshaft Position Actuator Solenoid
- Exhaust Camshaft Position Actuator Solenoid harness is open or shorted
- Exhaust Camshaft Position Actuator Solenoid circuit poor electrical connection
- Faulty Engine Control Module (ECM)

code p0014 refers to camshaft position(CMP) actuator . exhaust /right /rear bank 1--timing over advanced/system performance===causes valve timing--engine mechanical fault--CMP actuator . If you have done no work on the engine then I would be replacing the exhaust cam actuator (CMP actuator)

The code P0014 is for Camshaft Positon Sensor Actuator Bank 1. The possible causes are incorrect camshaft timing, wiring problems (harness/wiring) in intake timing control valve solenoid system; continuous oil flows to VCT piston chamber or failed timing valve control solenoid(stuck open).
The code P0015 is for Camshaft Position -Timing Over-******** (Bank 1). Your problem will probably be that the timing will be slightly out, due to wear (stretch) of the timing chain; this will all be linked to the overall cold start issue and the timing position. Get that timing checked, or push for the full fix for the cold start timing issue.

P0015: Camshaft Position, Act B - bank 1, timing over

P0014: Camshaft Position, Act B - bank 1, timing over advanced
Check oil level and quality.
Remove n clean exhaust camshaft vanost actuator.
Do not refit to exhaust cam, but swap with inlet actuator.
clear codes...if eml on again see if fault moved to inlet cam. If so replace the actuator.

DTC P0014
Circuit Description
The cam phasing system is a hydraulically actuated phase shifting mechanism. The powertrain control module (PCM) supplies the ignition positive driver and ground circuits. A pulse width modulated (PWM) driver controls the amount that the camshaft actuator solenoid assembly advances or retards the exhaust camshaft. The exhaust camshaft is commanded to a maximum ****** position of 25 degrees. When the exhaust camshaft is retarded at the maximum rate, the duty cycle of the signal is at 100 percent. The maximum advance rate has a 0 percent duty cycle. Other than when the camshaft is at full advance, a 50 percent duty cycle is used to maintain a steady ****** angle.
If the desired and actual cam phase angle error exceeds its tolerance value for a certain amount of time, then DTC P0014 will set.
Condition/Concern:
On rare occasions, a rough idle may be encountered with a P0014 and/or P0017 DTC. Due to the rough idle, a P0106 DTC may be stored too. This concern may be due to debris in the camshaft actuator system, which may be caused by a missing camshaft actuator solenoid screen or a worn crankshaft thrust bearing. Typically, this is the result of a camshaft actuator solenoid concern. If this is due to a worn crankshaft thrust bearing, some customers may also comment on a drive belt noise.

Recommendation/Instructions:
If this concern is encountered, follow the SI diagnostics and repair as necessary. If the SI diagnostics do not isolate the cause of this concern, ensure that camshaft actuator solenoid screens 1, 2, and 3 are in place.

(1) Screen for Advance Pressure to Camshaft Actuator
(2) Screen for Pressurized Oil from Oil Pump
(3) Screen for ****** Pressure to Camshaft Actuator

If any of these screens are missing, replace the camshaft actuator solenoid, change the engine oil and filter, and evaluate the concern.

If all these screens are present, measure the crankshaft end play to determine if it is within the specification of 0.0044" - 0.0153" (0.112 - 0.388 mm). Typically, if excessive crankshaft end play is causing this concern, it will be obviously out of specification by .050" or more. If crankshaft end play is within specification, replace the camshaft actuator solenoid.

If the crankshaft end play is obviously out of specification, inspect the engine block for damage due to contact with the crankshaft.

If there is no engine block damage present, disassemble the engine and inspect the following components for damage due to thrust bearing debris in the engine oil: all bearings, all journals, all valvetrain components, all timing components, and the crankshaft

DTC P0014 Exhaust Camshaft Position (CMP) System Performance.

The cam phasing system is a hydraulically actuated phase shifting mechanism. The powertrain control module (PCM) supplies the ignition positive driver and ground circuits. A pulse width modulated (PWM) driver controls the amount that the camshaft actuator solenoid assembly advances or retards the exhaust camshaft. The exhaust camshaft is commanded to a maximum ****** position of 25 degrees. When the exhaust camshaft is retarded at the maximum rate, the duty cycle of the signal is at 100 percent. The maximum advance rate has a 0 percent duty cycle. Other than when the camshaft is at full advance, a 50 percent duty cycle is used to maintain a steady ****** angle.

Remove Cam Phaser Solenoid and inspect it to ensure that all 3 screens are intact. Chances are you will need to replace this Solenoid and change the oil immediately.
