New kid in town.

That's about the same mileage that was on my 2007 when I bought it a year ago. At 243K now, I'm still very happy with it.

This link should help.

welcome!
the gas cap should only be tightened to one click. then, it takes a few runs for the light to go out.
all the best!

 

TPMS flashes because the batteries are dead in the sensors. The batteries are sealed you must buy the sensor amazon.com $50 each then when installed they have to be paired with the software in the car. There serial number must be installed.

CEL is most likely your very low on engine oil. Do that a few times and it may damage your motor.
At your miles it most likely eats oil how much is for you to determine. Check the oil first thing in the morning before starting the car for true oil level. If you pull over and check it then it will read low on the dipstick as the oil needs quite a long time to drip back into the pan..

 

TMPS light also obviously could just be one of your tires' pressure is low. But based on the year of your car, one or more of the sensors is probably bad; they're designed for a 10 year lifespan. Most people continue to drive and just ignore this light until the next time they need new tires, then replace all of them.

Go to an auto parts store and get the OBD codes read for your check engine light. Most auto parts store will do this for free - just take your cellphone to take pictures of their code reader. Google what comes up and if you can't solve it yourself, post back here.

 

i've never heard of the multiple clicks to correct it, so i can't answer. the o/m says not to tighten more than one click.
i don't think it's miles, but the number of times you start and stop the car. most people report a few days to a week.

 

crossed mine too!

 

Probably a bit premature on the diagnosis considering the limited info.

As I'm sure you know, CEL could be literally many things. I don't want to speculate. Have you read the code(s). An ELM 327 dongle on Amazon or Ebay, ($10) and the Torque app ($5) are invaluable and work on any car.

 

For the CEL stop into an Auto Zone or O'Reilleys and borrow their scanner and scan it in the parking lot.

Hopefully it is a P0101: "Mass or Volume Air Flow Circuit Range/Performance"
The fix is taking a short/stubby phillips and unscrewing the MAF sensor on front of motor and spraying it a couple times with cleaner....then clearing code...

Basically a free 5 minute fix...But obviously it could be a million things.

 

I believe this problem will get code p0420, catalytic converter problem

 

You still need code read when it is on otherwise it is anyone's guess. But sounds like it is a very minor problem.

 

Quick, go buy a lottery ticket
