Question

What does code P0016 mean?

Engine code P0016 is defined as “Camshaft Position A – Camshaft Position Correlation (Bank 1),” indicating that the camshaft and crankshaft are not in sync.

For the effective and safe operation of your car, both these shafts should be aligned properly and operate in sync. The powertrain control module (PCM) finds the position of both shafts using the info from the camshaft and crankshaft position sensors. The PCM will log this error code and turn on the check engine light if it senses from the sensor data that the camshaft and crankshaft are not in sync.

What are the symptoms of the P0016 code?

These are some of the signs that your car shows when the PCM logs this error code:

• The check engine light illuminates
• A rattling sound from the engine
• The car’s engine cranks but doesn’t start
• Poor engine performance
• Engine misfires
• When idling or driving at low speed, the engine stalls
• Fuel consumption increases

What can cause a P0016 code?

These are some causes that lead to the error code showing up in your car:

• A defective camshaft sensor
• Faulty crankshaft sensor
• The oil level is low
• Damaged or stretched timing belt or timing chain
• Loose connections or faulty wiring
• Defective crankshaft or camshaft reluctor wheel
• Faulty variable valve timing (VVT) actuator
• Defective variable valve timing (VVT) solenoid
• Issues with the PCM
• Misalignment of the timing chain/belt

How to fix code P0016

These are some ways you can fix this error code.

Replace the camshaft position sensor

As a defective camshaft position sensor can cause the code P0016 to show up, you must replace the sensor to bring back the correct timing sync.

Replace the crankshaft position sensor

A defective crankshaft position sensor can also lead to this code. You can correct the timing issues by replacing the sensor.

Adjust or change the timing chain tensioner

It is the timing chain tensioner that retains the proper tension of the chain. If it becomes faulty, the chain becomes loose, and the timing becomes wrong. Replace the tensioner to fix the issue.

Inspect and replace the oil control valve

The timing can go wrong if the oil control valve is faulty. Replacing this valve can resolve this issue.

Checking the engine for damage

Internal engine issues, like broken sprockets or timing chains, can cause the code to show up. You should have a strict inspection for required repairs or replacements.

How much does it cost to fix the P0016 code?

The cost to fix the P0016 engine code can vary based on the type of repair required. For instance, an oil change can cost between $50 and $200, whereas the cost to replace a camshaft or crankshaft sensor can be between $200 and $700. However, the cost to replace the timing chain can be between $400 and $2,000+.

Can I drive with a P0016 code?

No, you should never drive your car with this error code. The code indicates a severe problem that needs to be addressed quickly. Ignoring this error code and continuing to drive the car will cause extra damage to the internal engine components, causing the repair cost to increase considerably.
