My engine was fixed. I believe they played with the timing chain and now I have those two codes.

Good afternoon,

What was repaired on the engine? Please give me the details.

Both codes are related to the timing chain.

Okay, thank you.

They have the timing chain on wrong.

Return the car to the repair shop and have them set the timing correctly.

I attached a diagram of the lower chain that is most likely the issue.

I attached a YouTube video of the procedure for you.

Replacing the camshaft position sensor and crankshaft position sensor could be a solution?

No, not at all. The timing is incorrect. The sensors just send a signal to the ECM. They have nothing to do with adjusting the timing.
