P0017: Crankshaft Position - Camshaft Position Correlation (Bank 1 Sensor B)
Can you still drive? Minimize driving. Timing correlation issues can worsen quickly and lead to catastrophic engine failure on interference engines. Have it diagnosed as soon as possible.
What Does P0017 Mean?
Code P0017 indicates that the crankshaft and exhaust camshaft on bank 1 are not in the expected positions relative to each other. The ECM continuously monitors the relationship between these two shafts, and P0017 is set when the deviation exceeds allowable limits. This commonly results from timing chain wear or VVT system malfunction.
Need to read your codes?
An OBD-II scanner lets you read and clear diagnostic trouble codes from your vehicle's computer. Most scanners work with any car made after 1996.

Frequently Asked Questions
Is P0017 the same as P0016?
They are related but different. P0016 refers to the intake camshaft correlation on bank 1, while P0017 refers to the exhaust camshaft correlation on bank 1. Both indicate a timing issue.
Can low oil cause P0017?
Yes. The VVT system relies on oil pressure to adjust camshaft timing. Low oil level or degraded oil can cause the system to malfunction and trigger P0017.
What vehicles commonly get P0017?
GM vehicles with the 2.4L Ecotec engine (2010-2017 Equinox, Terrain, Malibu) are particularly prone to this code due to known timing chain stretch issues.
