Error P0016 – how to fix it?

Definition of the P0016 code

Camshaft position A – Correlation of camshaft position (Bank 1)

What does code P0016 mean?

P0016 is a generic OBD-II code that indicates that the crankshaft position sensor in bank 1 does not correlate with the crankshaft position sensor signal.

What is the cause of the P0016 code?

• The camshaft timing is misaligned because the timing chain has jumped teeth.
• The shift lever is out of position because of problems with the shift lever.
• Oil flow to the phaser is obstructed by inadequate oil viscosity or partially blocked channels.
• The oil control valve (OCV) has a restriction in the OCV filter.

What are the symptoms of code P0016?

• Engine control light comes on.
• Engine may have reduced power or difficulty starting.
• The engine may run abnormally, stall, hesitate, or run erratically.
• The engine mileage will decrease.

Note: Claims about erratic driving will vary depending on the fault.

How can a mechanic diagnose the P0016 code?

• Visual check for problems with the OCV valve connections or wiring, camshaft and crankshaft sensors.
• Check that the engine oil is full and clean, with the correct viscosity.
• Analyzes and documents the engine codes and reviews the freeze frame data to see when the code was set
• Resets the engine light and retests the road to see if the code reappears
• Turn the OCV on and off to see if the camshaft sensor indicates timing changes for the camshaft in bank 1.
• Perform manufacturer’s tests for code P0016 to determine the cause of the code.

Note: The manufacturer’s recommended troubleshooting test is used to narrow down the problem. Performing the recommended tests will help with diagnosis without replacing the wrong parts.

Most common errors in the diagnosis of P0016 code

• Failed to check for faults and codes before undertaking any repairs.
• Failure to visually inspect for any problems with cables or connections to components.
• Failure to perform all steps of the comparison test to avoid misdiagnosis of good components.
• Failure to replace parts indicated by the comparison test or visually check for damage.

How serious is the P0016 code?

• The engine may stutter or hesitate and have difficulty starting.
• The timing chain may have problems with the tensioners or guides and may lead to further engine damage if the valves hit the pistons.
• Driving a car for a long period of time with a timing chain can cause additional internal engine problems, depending on the damaged part.

What repairs can clear the P0016 code?

1. Reset the error codes and perform a road test.
2. Replace the camshaft sensor on seat 1.
3. Repair the wiring or connection to the camshaft OCV valve or camshaft sensor.
4. Replace the camshaft OCV valve in position 1.
5. Replace timing chain and guides

Additional notes on code P0016

The P0016 code may be because the camshaft sensor in bank 1 has an intermittent internal problem caused by vibration or high temperature. These problems may or may not be verified. If repeated attempts to find the fault do not result in a verified code, a faulty camshaft sensor should be suspected.
