Is the P0017 fault code caused by a skipped tooth?

[DelJohnny]

P0017 fault code does not necessarily mean a skipped tooth. The P0017 fault code indicates an unreasonable correlation between the crankshaft position and the exhaust camshaft position. There are multiple causes for this fault code, and a skipped tooth is just one of them. Causes of the P0017 fault code: 1. Abnormal oil pressure; 2. Stuck VVT solenoid valve; 3. Faulty VVT actuator; 4. Chain skipped tooth or tensioner pressure loss; 5. Faulty camshaft and crankshaft position sensors or signal disc; 6. Damaged ECU. Solutions for the P0017 fault code: 1. Check if the crankshaft position signal disc is dirty or damaged, and clean or replace it if necessary; 2. Swap the intake and exhaust VVT solenoid valves and camshaft sensors; 3. Remove the timing chain and replace both VVT gears.
