Today I did a module by module fault-checking and I cleared every code. Then I did a new automatic fault-checking, and there were a few new codes that I am curious about. I have copied & pasted them below.

Please let me know if there is anything you know about these, or if there is something I should try. I'm all ears.

(I didn't post all fault codes. A lot just said "No Signal/Communication", and I think that just means I do not have those specific features on my car. Like a TV Tuner, convertible top, etc.)

Hello xclens,


My thougt is to delete the fault codes. Drive a couple days and re scan.


Two notable codes which may return are the turbo position sensor and lean at Idle faults. Drive the car a couple days after the code(s) deletion. A couple short accelerations to run the turbos will aid in this evaluation.

Thank you, I will do so. I'll report back here in a few days!

 

You could have multiple issues resulting in low voltage at several locations, but this would make me question the health of the "house" battery. If your battery is ~4 years or older, then I would replace it before replacing any other components. Good luck!

 

For what it's worth when I had P0546 I had the check engine light on and it proved to be exhaust gas temp sensor bank 1 failure.
Replaced the oxygen temp sensor and the check engine light disappeared.
