P0014 Diagnostic code, already replaced camshaft actuator & oil twice

If this DTC sets, there is a problem with the camshaft position actuator solenoid high control circuit shorted to voltage or the solenoid stuck open.
The PCM sends a pulse width modulated 12 volt signal to a (CMP) actuator solenoid in order to control the amount of engine oil flow to a cam phaser passage.
Do you know what a pulse width modulated signal is ?
Diagnostic Aids
Important: Scan tool control of the CMP actuator solenoid is inhibited when DTC P1345 sets.
The following conditions may cause this DTC to set:
• An improperly torqued harmonic balancer
• A mis-built or mis-timed engine
• A loose or missing crank damper bolt
• The camphaser solenoid stuck open
• The camphaser stuck in a position other than 0 degrees
• The camphaser does not return to 0 degrees within 16 seconds

Do you know what a diagnostic flow chart is ?

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)

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.

Its a cam over-retarded code.

I believe this is a rebranded chevy trailblazer. I would start with an exhaust cam actuator which is located right next to the power steering pump. 90% of the time this will fix the problem. If it does not than it is possible there is an issue with the timing chain or a PCM issue.

Hello billscranese,

The P0014 is a cam phasing code. The phasing system is a hydraulic actuated phase shifting system and is vulnerable to dirty oil. If its been sometime since your last oil change I would recommend that you start with that. The control module turns off the MIL after 3 consecutive ignition cycles that the diagnostic runs and does not fail.

The P1345 could be caused by the P0014. The powertrain control module monitors the correlation between the crank and cam positions and if the deviation between the two exceeds a predetermined amount it will set the code.

Good luck.

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.
