The P0017 trouble code indicates that the engine control module (ECM) has detected a fault with the timing of the exhaust camshaft on the right cylinder bank. Specifically, it indicates that the camshaft is constantly being adjusted in the "advanced" direction.
Here are some steps you can take to diagnose and fix the issue:
Check the oil level: Low oil pressure or low oil level can cause problems with the variable valve timing system. Make sure the oil level is correct and the oil pressure is within specifications.
Inspect the camshaft position sensor: The camshaft position sensor is responsible for detecting the position of the camshaft. A faulty sensor can cause the ECM to misinterpret the position of the camshaft and adjust the timing incorrectly.
Check the timing chain: A worn or stretched timing chain can cause problems with the variable valve timing system. Check the timing chain and associated components for wear and replace if necessary.
Inspect the VVT solenoid: The variable valve timing (VVT) solenoid is responsible for controlling the oil flow to the camshaft phaser. A faulty solenoid can cause problems with the variable valve timing system.
Check for wiring issues: Wiring problems can cause faults with the camshaft position sensor or VVT solenoid. Check the wiring for damage or loose connections.
Inspect the camshaft phaser: The camshaft phaser is responsible for adjusting the timing of the camshaft. A faulty phaser can cause problems with the variable valve timing system.
Based on the findings from the above steps, repair or replace any faulty components that are causing the issue. If you are not able to diagnose or fix the issue on your own, it is recommended to take your vehicle to a certified mechanic or dealership for further diagnosis and repair. A professional may be able to perform a more thorough inspection of the engine and identify any other issues that could be causing the problem.
