How many miles?

Let me clarify.
He suspects the timing chain.
He did not inspect the timing chain, and could not guarantee that was the issue.
Wanted and additional $4000+ for the work.

The vehicle is showing no signs of timing chain issue. Drivability is good, 40+ mpg, no abnormal noise, no rough idle.

4Cyl
127000 miles

So, you know better than the mechanic?

Do you know what those codes mean?

They're indicative of timing correlation issue.

The vehicle has no symptoms of timing issues.

The mechanic could not guarantee, nor did he inspect the timing chain.

They could also be indicative of low, bad, incorrect oil.

However, the oil was changed as well.

DTC Description
This diagnosis checks the camshaft position plausibility whether the expected range plus some margin is not violated that might be caused by a wrong engine repair, or a chain/belt misalignment. DTC P001700 is set when actual camshaft position is too much retarded or advanced than full retard position or full advance position. To continue the adjustment in such case could lead to a damage of the engine by hitting the valves with the piston.

It's pretty apparent you don't want to hear anything that you don't agree with so I don't believe we will be any help to you.

This is a case of a little knowledge can be dangerous.

I could look up and quote exact ASE definitions too, if I wanted to.

I also can research and inquire as to symptoms of timing chain issue, none of which my vehicle shows.

It never hurts to get a second opinion (on any subject in life), specifically when the diagnosis doesn't fit the symptoms and no firm evidence can be presented, other than an "educated guess".

There are a multitude of minor issues that could cause the ECU to trigger codes that are inaccurate. There are also multiple diagnoses for each code.

If you have no valuable input, that is acceptable.

If you would like to offer a possible alternate solution, that would be acceptable as well.

You can just keep throwing parts at it and telling the mechanics they don't know what their talking about.

I'm closing this question now because you know more than everyone else already.
