Error Code P0016: What It Means & What To Do?

<<See All OBD Codes

If you are experiencing problems like engine stalling and not starting as well as increased fuel consumption and Check Engine light illuminating, then it may be due to occurrence of OBD code P0016. 

The error code P0016 is triggered when the bank 1 camshaft position sensor doesn’t match the signal from the crankshaft position sensor. This can cause various issues with the overall functioning of the engine and can lead to increased fuel consumption and rough engine idling.

The “A” Indicates the Intake Camshaft, located to the intake side of the Cylinder Head. “Bank 1” denotes the Engine Bank that contains the Number One Cylinder.

What causes this problem with the Camshaft Position Correlation?

• The timing chain jumped teeth can be a reason why the camshaft timing can get out of position
• There can be some problems with the phasor due to which the camshaft phaser is out of position
• The incorrect oil viscosity or the partly clogged passages can be a reason why oil flows to the phasor is impeded
• The oil control valve may have a restriction in the OCV filter

1. Camshaft & Parts - A faulty camshaft can be troublesome. You can always rely on us as we have best auto parts for our customers.
2. Oil Filters & Parts - Oil Filter is an important car part which should never be neglected. May be there is some fault in it due to which P0016 code may start flashing.
3. Timing Chain - Are you facing OBD Error Code P0016? Don’t worry as you can fix this issue with new timing chain. We care for our customers, that’s why we have timing chain for every make and model.
4. Wiring Connectors - Damaged or worn out wiring hampers the functioning of the sensors and the circuits thus affecting the fuel delivery system. Thus, they are needed to be checked properly are replaced, if damaged.
5. Auto Switches & Sensors - Common causes behind that P0016 error code can be defective switches or faulty sensors. So, it will be a good decision to replace them now.
6. Powertrain Control Module - P0016 error code also relates to problems with the powertrain. If the PCM is damaged it needs replacement or reprogramming. Find all the Powertrain related parts with us.
7. Oil Control Valve - Do you remember when was the last time you got your car oil control valve checked up? A damaged oil control valve can cause a lot of issues like displaying P0016 code.
8. Diagnostic Tool - In order to detect the error, one needs high grade diagnostic tools. Visit us today to buy quality tools and equipment.

There are several common symptoms of an error code P0016, which can include:

Common Symptoms

• The check engine light will be illuminated
• The engine may perform erratically, running rough or stalling
• The engine may have a hard start or you may notice a reduction in power
• Fuel consumption will increase

Issues with the functioning of the engine will largely be determined by the exact cause of the fault, so it may not be present when the error is triggered.

It is important to recognise the components that need to be examined properly so that the correct parts can be replaced or repaired for correct functioning of the fuel delivery system and engine control module.

• Use OBD-II scan tool and examine the code. Reset the code and test drive the vehicle again to see if the code reappears
• If the camshaft sensor on Bank 1 is found faulty, it is needed to be replaced
• Examine the wiring/connections to the camshaft OCV or camshaft sensor and replace if found damaged/worn out
• Replace the camshaft OCV for Bank 1 exhaust camshaft for found problematic
• Check the timing chain and replace if not functioning properly

The manufacturer's recommended pinpoint test is used to narrow down the problem. Following the recommended tests will help with diagnosis without replacing the wrong parts. Visually checks for problems with the connections or wiring of the OCV, camshaft and crankshaft sensors

• Verifies that the engine oil is full and that the oil is clean with the correct viscosity
• Scans and documents the engine codes and views the freeze frame data to see when the code was set
• Resets the check engine light and road tests again to see if code returns
• Commands the OCV on and off to see if the camshaft sensor is indicating timing changes for the bank 1 camshaft
• Performs the manufacturer’s tests for the P0016 code to determine the cause of the code

Common Mistakes When Diagnosing the P0016 Code

• Following are the mistakes which are often made while treating P0016 error code.
• Not inspecting the error code and problems before diagnosing
• Not checking the wiring and connection problems to the circuit and sensors
• Not following the diagnostic steps to avoid misdiagnosis of correct components
• Not using the proper scanner to find the problematic components and just relying on visual inspection
