Today, I want to talk about a common issue I’ve encountered with the P0016 and P0017 error codes on the 1.4-liter engines of Chevrolet Trax and Chevy Cruze.
I recently worked on a 2014 model that was experiencing loud rattling in the engine and overall poor performance. Upon investigation, I discovered that the timing chain was causing the problem.
When I removed the valve cover, I noticed that the timing chain was extremely loose, moving excessively. This led me to inspect the timing chain cover, where I found brittle and broken pieces of the chain tensioner and guides.
The seized tensioner and damaged guides were the culprits behind the rattling and improper functioning of the engine, resulting in the P0016 and P0017 codes.
If your engine is not exhibiting rattling noises but you’re still getting these error codes, it’s advisable to inspect the sensors located on the side of the cover. One or both of these sensors could be causing the issue, especially if the error codes appear individually rather than simultaneously.
In my case, the simultaneous appearance of both codes pointed towards the timing chain, but for a single code, it’s likely a sensor malfunction.
So, in conclusion, if you’re facing P0016 and P0017 codes, it’s essential to address the timing chain, cam sensors, and related components to resolve the issue and restore your engine’s performance.
Thank you for watching!
What are the P0016 and P0017 codes for?
The P0016 and P0017 codes are related to the timing chain in a 1.4 liter engine used in the Chevy Trax and Chevy Cruze. These codes indicate issues with the timing chain, such as rattling and improper engine function.
How can I diagnose the issue with the timing chain?
If you encounter loud rattling in the engine and the engine is not running properly, it is advised to inspect the timing chain. To diagnose the problem, you may need to remove the valve cover and check the condition of the timing chain and related components, such as the tensioner and guides.
What should I do if my engine is not rattling but I am getting the P0016 and P0017 codes?
If the engine is not making rattling noises but the P0016 and P0017 codes are present, it is recommended to check the sensors located on the side of the cover. If only one code appears, it may indicate an issue with the sensors, whereas both codes showing up simultaneously often point to a problem with the timing chain.
