When the check engine light comes on, the last thing a driver wants to see is a confusing code—like P0017. This code stands for "Crankshaft Position - Camshaft Position Correlation Error (Bank 1 Sensor B)" and often indicates a problem with the engine's timing system.
Don't worry, this article will help you fully understand the true meaning of P0017, common causes, and repair solutions, as well as how to quickly identify the root cause using the Autel MK900BT Smart Scanner.
A P0017 code may be detected when the check engine light is on.
P0017 is a timing signal desynchronization error detected by the engine control module (ECU/PCM).
It indicates that the signals between the crankshaft sensor and the camshaft sensor have deviated from the expected synchronization range.
Simply put, the crankshaft drives the pistons, while the camshaft controls the opening and closing of the intake and exhaust valves. When these two movements are out of sync, the engine's combustion, ignition, and fuel injection timing are disrupted, resulting in unstable operation, difficulty starting, and even stalling.
"Bank 1" typically refers to the side containing cylinder number 1, and "Sensor B" often refers to the exhaust camshaft sensor. However, the definitions vary slightly between brands and models.
The descriptions of this code may differ slightly on Chevrolet, Hyundai, Toyota, Ford, and other models, but the underlying issue is the same: a disruption in the timing between the crankshaft and camshaft.
P0017 means the crankshaft and camshaft sensor signals are out of sync.
In addition to the engine check light, your vehicle may also exhibit the following symptoms:
These symptoms can also be caused by other issues, so using a professional scanner to read the fault data is key to determining the true cause.
One sign of P0017 is increased fuel use.
The following are common causes of this code:
Camshaft signal lag can result from chain wear or a loose tensioner.
The Autel MK900BT is an intelligent automotive diagnostic tool for DIY car owners and professional technicians. It supports over 40 service functions and full system diagnostics, accurately reading and clearing all OBD-II fault codes, including P0017.
Instructions for use:
The MK900BT uses wireless Bluetooth connectivity, eliminating the need for tangled cables.
Select [Read DTCs] to confirm whether P0017 appears.
Monitor the crankshaft and camshaft signal waveforms in real time to check for any offset.
Activate the VVT solenoid valve and check for normal response.
Analyze engine speed, load, temperature, and other data at the moment the problem occurs.
Compared to standard scanners, the MK900BT can more accurately pinpoint the root cause of the problem and supports recording and exporting diagnostic reports, helping technicians quickly identify repair options.
Depending on the diagnostic results, repairs may include:
Some owners have shared that after confirming the issue using the Autel MK900BT, they successfully cleared the P0017 error by simply replacing the VVT solenoid and engine oil, a process that took less than 20 minutes.
Use Autel scanner to test vvt data.
P0017 indicates a desynchronization between the crankshaft and camshaft position signals, a critical issue in the engine timing system.
Ignoring this code can lead to severe internal engine wear or valve impact on the piston.
Using the Autel MK900BT Smart Scanner, you can:
If you frequently perform maintenance on your vehicle yourself, the MK900BT is one of the most worthwhile diagnostic tools you can invest in your garage.
Continuing to drive is not recommended. P0017 involves the engine timing system, and if the problem worsens, it can cause serious mechanical damage.
It depends on the problem. Replacing the sensor costs approximately $200–400, while replacing the timing chain can cost over $1,000.
Yes. The MK900BT not only reads and clears a P0017 fault code, but also helps identify the root cause through real-time data streaming, waveform analysis, and proactive testing.
