code P0016

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. So sorry to hear you're having trouble with your Impala. Code P0016 indicates a correlation issue between the camshaft and crankshaft position sensors. In simple terms, these two sensors aren't in sync, indicating a problem with engine timing. Common causes include a stretched or worn timing chain, a faulty camshaft or crankshaft position sensor, or an issue with the timing chain tensioner. Since the issue has been going on for months, it's important to get this checked out to avoid further damage to the engine. If you need more advice, have any other questions about your vehicle, or would like to get connected to a RepairPal Certified shop near you, we have you covered.
