Have The P0016 Code? Fix It With These Proven Diagnostic and Repair Steps

When your car’s check engine light suddenly comes on, it brings a handful of codes like the P0016 code, which pops up when you plug in your scan tool. If your vehicle has this code, you’re likely facing a problem with your engine’s timing, camshaft position correlation, and crankshaft position correlation system. In this post, we’ll dive deep into the code to learn its definition, what triggers it, and what you can do to fix it. So, if you’re ready, let’s get started.

P0016 Code Definition and Meaning

The P0016 OBD-II code is a fault code that indicates a synchronization problem between the camshaft position sensor (CMP) and the crankshaft position sensor (CKP). When this fault code appears, it shows that the readings from these two sensors are not aligning correctly.

Both sensors provide vital data to the Powertrain Control Module (PCM), which, in turn, uses that information to control the fuel injectors and adjust the ignition timing. When the code is triggered, the PCM detects a discrepancy in the timing between the camshaft and the crankshaft. 

Common Symptoms and Engine Light Indicators

When the code rears its head, you will likely notice some of the common signs below

• Illumination of the Check Engine Light (CEL): This light appears when the engine control module (ECM) detects a fault or issue.
• Engine Misfires: With the code, you’ll experience engine misfires, often accompanied by a noticeable sputter or rough running.
• Poor Engine Performance: You might notice a reduced power output, sluggish acceleration, abnormally low engine RPM, and a general decline in engine responsiveness. 
• Difficulty Starting the Engine: You might need to try starting the engine multiple times before it fires up properly.
• Hard Starting, Hesitation, and Stalling: If the timing is off, your engine might fail to run at idle speed or stall randomly.

Causes of the P0016 Code

Dwell on these causes for the next few seconds.

• Engine Timing Issues: Issues with the engine’s timing system can cause the code to appear.
• Faulty Camshaft Position Sensor: If the camshaft position sensor is damaged, it can provide incorrect readings, which triggers the code.
• Faulty Crankshaft Position Sensor: A faulty position sensor for your crankshaft can also send inaccurate data to the car, leading to this code appearing.
• Timing Chain Issues: Problems with the timing chain, such as a rattle during a cold start, can also lead to the P0016 code.
• Incorrect or Defective Sensor Signals: If these sensors (camshaft sensor and crankshaft sensor) are defective, they may send inaccurate signals to the PCM, and the P0016 code will appear.
• Damaged Camshaft Drive System: Broken bolts, loose magnets, or other forms of damage in the camshaft can affect the timing and cause the P0016 code to appear. 

Diagnosing the P0016 Error Code

You can diagnose the P0016 error code by following the steps below

• Use an OBD-II Scanner: Use an OBD-II scanner to run a diagnostic check for the trouble code p0016
• Verify the Codes: Verify that the p0016 code is present and if there are other codes. You may need to do a pinpoint test.
• Carry Out a Pinpoint Test: If necessary, conduct a pinpoint test to help you narrow down the exact cause of the code. Your position correlation bank one sensor may not be in tune with the harmonic balancer.
• Check Wiring and Connections: Wiring and poor connections may indirectly cause the code to appear. Take a look at the relevant wires.
• Inspect the Engine Front Cover Area: Check for previous repairs to see if any parts are installed incorrectly or if damaged components in this area affect the cam position sensor.

How to Fix Code P0016

If you’ve diagnosed the P0016 error code, you can take the following steps to fix it

• Replace the Faulty Camshaft or Crankshaft Position Sensor: If the camshaft position or crankshaft position sensor (cam and ckp sensors) is malfunctioning, replace them. You can get them and other top-quality automotive engine parts here at Nanjing Woda Auto Technology Co., Ltd.
• Repair or Replace Damaged Timing Chain/Belt: You should replace your timing chains and belts when they weaken and wear out. A timing chain tensioner will come in handy.
• Fix Worn-Out Reluctor Rings: If the tone rings on the camshaft or crankshaft are worn or damaged, replace or fix them.
• Do an oil change: Change the engine oil and filter to ensure the engine runs smoothly with new oil. This oil change will also ensure the engine attains its normal operating temperature.
• Check and Repair Any Wiring Faults: Inspect the wiring that leads to the sensors (crank sensor and cam sensors). If you find any faults, repair them immediately.

How Much Does It Cost to Fix the P0016 Code?

DIY Vs Professional Repair: Which Should You Go For?

You can either embrace DIY for this or get a trusted mechanic to fix the code p0016 on your vehicle’s computer system.

• Parts Costs: You can save on labor fees but need to purchase replacement parts. Labor costs for professionals fall between $100 and $900 (at $50 to $150 per hour), assuming it takes 2 to 6 hours. 
• Tools and Equipment: Even for DIY repairs, you’ll need certain tools like wrenches and sockets, and if you don’t already own them, you’ll have to purchase them. Professionals already have them.
• Time and Expertise: If you’re not experienced with engine repairs, a 2-hour job for a professional mechanic might take you a full day or more. And a professional may also offer you a good warranty.

It’s your choice!

Risks of Ignoring the P0016 Code

Whether you choose to DIY or hire a professional, one thing is clear: ignoring the P0016 code is not an option. Here’s why:

• Potential Engine Damage: The P0016 code indicates a timing issue between the camshaft sensor and the crankshaft position system. If this issue is left unresolved, it can cause severe engine misfires, poor fuel efficiency, or even complete engine failure in the worst case. 
• Difficulty Starting or Stalling: The code may cause hard starting, stalling, or hesitation during acceleration. This makes driving such a vehicle a bad idea. Additionally, it will also increase the wear and tear on your car.
• Worsening of the Problem: The longer you wait to fix the issue, the more likely the problem will escalate. A minor misalignment could turn into a full-blown timing chain failure.

Preventing P0016 in the Future

Here’s what you should focus on to keep your engine running smoothly and avoid triggering the P0016 code again.

• Regular Oil Changes and VVT System Maintenance: Dirty or low oil can affect the VVT system, leading to camshaft and crankshaft timing issues. Make sure to follow your vehicle manufacturer’s recommended oil change intervals, typically every 3,000 to 7,500 miles, depending on the type of oil you use (conventional, synthetic, or high-mileage). 
• Inspecting Timing Components Periodically: If your vehicle uses a timing belt, replace it every 60,000 to 100,000 miles. Although the timing chains last longer, don’t forget to check them regularly. 
• Using OEM-Quality Replacement Parts for Long-Term Reliability: When replacing any components related to the timing system, always opt for OEM-quality parts. While aftermarket parts may be cheaper, they often don’t meet the same quality standards as most OEM parts.

Conclusion & Call-to-Action

Dealing with the P0016 error code can be frustrating. However, if you do the necessary things like what we’ve pointed out, you address the issue and prevent it from happening again. You should diligently maintain your engine, regularly inspect timing components, and use OEM-quality parts.
