P0016 2014 GMC Sierra Code - Crankshaft Position - Intake Camshaft Position Not Plausible

Quick Answer

The Camshaft Position (CMP) actuator system is controlled by the control module. Common causes include Low oil level, Mechanical timing fault (stretched timing chain or damaged timing chain tensioner), Blocked oil passage. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0016 2014 GMC Sierra Description

The Camshaft Position (CMP) actuator system is controlled by the control module. The Engine Control Module (ECM) sends a pulse width modulated signal to a CMP actuator solenoid in order to control the amount of engine oil flow to a camshaft actuator passage. There are 2 different passages for oil to flow through, a passage for CAM advance and a passage for CAM retard. The camshaft actuator is attached to the front of the camshaft and is hydraulically operated in order to change the angle of the camshaft relative to the Crankshaft Position (CKP). Engine Oil Pressure (EOP), viscosity, temperature, engine oil level, and aftermarket engine oil additives can have an adverse effect on camshaft phaser performance. The Diagnostic Trouble Code (DTC) will be set when the ECM compares the signals of the crankshaft position sensor and both camshaft position sensors to detect if the signals are out of sync.

Frequently Asked Questions about P0016 2014 GMC Sierra Code

What does OBDII code P0016 mean on a 2014 GMC Sierra?

Code P0016 indicates a mismatch between the crankshaft position sensor and the intake camshaft position sensor signals.

What are the symptoms of code P0016 on a 2014 GMC Sierra?

Symptoms may include rough idling, engine misfires, reduced power, poor fuel efficiency, and difficulty starting the engine.

What causes code P0016 on a 2014 GMC Sierra?

Common causes include a stretched timing chain, worn timing chain tensioner, faulty sensors, misaligned timing components, or contaminated oil.

Can a dirty or low oil level trigger code P0016?

Yes, dirty or low oil can affect the timing components and cause a misalignment of sensor signals, leading to code P0016.

How do you diagnose code P0016 on a 2014 GMC Sierra?

Diagnosis involves checking the timing chain for wear, inspecting the crankshaft and camshaft position sensors, verifying proper oil pressure, and using a scan tool to monitor sensor data.

Can driving with code P0016 damage the engine?

Yes, continued driving can cause further damage to engine components due to improper timing, potentially leading to severe engine failure.

How do you fix code P0016 on a 2014 GMC Sierra?

Repairs may include replacing the timing chain, sensors, tensioners, or correcting misaligned timing components. An oil change may also be necessary if contamination is present.

Is a timing chain replacement always required for code P0016?

Not always. While a worn timing chain is a common cause, other issues like faulty sensors or low oil pressure can also trigger this code.

Can code P0016 be caused by a faulty camshaft position sensor?

Yes, a malfunctioning camshaft position sensor can produce incorrect signals, leading to code P0016.

What tools are needed to troubleshoot code P0016?

A scan tool, multimeter, timing chain inspection tools, and basic hand tools may be required for diagnosis and repair.
