About the Terrain
The Terrain crossover SUV first made its debut in 2009. Since its release, only two generations have hit the markets. The second was released in 2018 and received an update in both 2021 and 2022.
During its time on the market, owners have reported a number of shaft issues to plague the Terrain. P0011 is one of the most common of these. This code indicates that the intake camshaft is over-advanced.
Similarly, fault code P0014 is another common issue for the Terrain. This is the same code but for the exhaust camshaft.
These can typically be the result of failing VVT valves. Another common cause is a faulty camshaft position sensor for the respective shafts. Despite being a serious issue, its common fixes for it are relatively simple and affordable.
These codes indicate that the signals from the intake and exhaust camshafts respectively are not correlating with the crankshaft signal.
All of these codes are very serious as they can lead to significant damage if left unchecked. Terrain owners should always tackle the first codes before attempting to solve the latter issues as resolving codes like P0011 can fix the other problems.
