Common Questions
What does P0016 mean and how does it affect my car?
P0016 indicates a problem with the timing of your engine's camshaft and crankshaft. This can lead to significant performance issues, such as reduced power and fuel efficiency. If ignored, it may cause serious engine damage.
What are the most common causes of P0016 and how much does it cost to fix?
Common causes include faulty sensors, worn timing components, and VVT system failures. Repair costs can range from $150 for sensor replacement to over $1,200 for timing chain replacements.
Can I drive my car with P0016 or should I stop immediately?
It's advisable to stop driving your vehicle if you see a P0016 code. Continuing to operate the car can lead to more severe engine damage, which will be much more costly to repair.
How can I diagnose P0016 myself using GeekOBD APP?
You can use the GeekOBD APP to connect to your vehicle’s OBD2 system, retrieve trouble codes, and view live data from sensors. Look for any discrepancies in camshaft and crankshaft readings.
What vehicles are most commonly affected by P0016?
Vehicles like the 2015-2018 Honda Civic, 2016-2019 Ford Explorer, and various models from Toyota and Nissan are frequently affected by this code. Be sure to check for any recalls or TSBs related to these models.
How can I prevent P0016 from happening again?
To prevent P0016, ensure regular oil changes, maintain the timing components, and check for any signs of wear or damage. Using high-quality oil can also help keep the VVT system clean.
What is P0016?
DTC P0016 stands for 'Camshaft Position A - Crankshaft Position Correlation Error (Bank 1)', and it indicates a mismatch between the camshaft and crankshaft positions. This code typically points to issues with the timing components of the engine, such as the timing chain or belt, variable valve timing (VVT) system, or sensor malfunctions. When there’s a timing mismatch, it can lead to significant engine performance issues. Drivers may experience rough idling, decreased power, and issues with fuel efficiency. If left unresolved, a P0016 code can lead to more severe engine damage, as incorrect timing can cause the pistons and valves to collide, resulting in costly repairs. Many vehicles, particularly 2015-2018 Honda Civic models, may encounter this code due to wear and tear or malfunctioning components. Therefore, understanding P0016 is crucial for maintaining engine health and performance.
System: P - Powertrain (Engine, Transmission, Emissions)
Symptoms
Common symptoms when P0016 is present:
- Check engine light stays on constantly, indicating a persistent issue that needs attention.
- Engine hesitates during acceleration, which can lead to a frustrating driving experience and decreased responsiveness.
- Fuel economy decreased by 10-15%, leading to more frequent stops at the gas station and increased expenses.
- Rough idling or stalling, especially during low-speed driving or while the engine is warming up.
- Unusual engine noises, such as knocking or ticking, which may indicate severe internal engine issues related to timing.
Possible Causes
Most common causes of P0016 (ordered by frequency):
- The most common cause is a faulty camshaft or crankshaft sensor, which can occur in approximately 60% of cases. This can lead to an inaccurate reading of the engine's timing.
- A worn timing chain or belt may also trigger a P0016 code, particularly in vehicles with high mileage (over 100,000 miles). Regular maintenance can help prevent this.
- Variable Valve Timing (VVT) system failure is another cause, often due to oil sludge buildup. Keeping up with oil changes every 5,000-7,500 miles can help prevent this.
- Less common, but serious, is a mechanical failure in the engine, such as bent valves or damaged pistons, which can cause catastrophic engine failure.
- A rare but possible cause is a software issue in the engine control module (ECM), which may require a reprogramming or update from the dealership.

Diagnostic Steps
Professional P0016 Diagnosis Process
Follow these systematic steps to accurately diagnose P0016. Each step builds on the previous one to ensure accurate diagnosis.
Step 1: Initial visual inspection - Check for obvious signs like damaged wiring, loose connections, or corrosion (5-10 minutes)
Step 2: OBD2 scan with GeekOBD APP - Retrieve all codes and freeze frame data to understand the fault context (10-15 minutes)
Step 3: Component testing - Use a multimeter or specific diagnostic tools to test suspected components, including camshaft and crankshaft sensors (20-30 minutes)
Step 4: System function test - Verify proper operation of the timing components and clear codes to check for reoccurrence (10-15 minutes)
Step 5: Road test verification - Drive the vehicle under various conditions to confirm repair success and monitor for any returning symptoms (15-20 minutes)
Important Notes
- Always verify the repair with GeekOBD APP after completing diagnostic steps
- Clear codes and test drive to ensure the problem is resolved
- Address underlying causes to prevent code recurrence
