So... Do I need to take this to the mechanic, or is it ok?
She lost her gas cap in October and got a replacement one from Autozone, and I'm wondering if it just isn't a good fit.
She's low on gas, and I seem to remember having some issue with my old Volvo when the tank got low, so just kept it full and it seemed to work. No idea if that contributes either.
Anyway, this is the Code from my handy dandy OBD II reader thing.

Replace the gas cap. It's the most common and is usually a cheap fix.
Will do, thanks. That sounds great.
yep, it's the gas cap 99% of the time. Replace it, ignore it, but either way curse the federal government for the heaping piles of regulations that make every car cost thousands more and then they wonder why the disadvantaged have a hard time getting by.
Try electrical tape. You know.. Put it over the check engine light.
This. It's generally where a guy plugs a little thingamajig in the whatchamacallit and resets it.Quote:

Evap Sensors are notorious for problems too.
- faulty vent control valve
- blockage at the vent hose, vent filter or vent control valve
- open or short in the vent control valve circuit
- bad charcoal canister
- EVAP system leak
- faulty EVAP system pressure sensor
- bad vacuum switching valve (VSV) (Toyota, Lexus)
- stuck open purge valve (solenoid)
Did you check the "Check The 'Check Engine Light' Light"?

It may need a new 710

Id' try percussive maintenance.
Tank isn't holding pressure. Most likely the above mentioned gas cap. Sometimes you can just take the cap off and retighten it.

This happened to me in a Toyota I had. I had to replace the Gas cap 3 times. I finally had to get one from Toyota for it to hold take pressure and not kick the light back on. I assume you are getting it reset after replacing the gas cap? Many times your computer will not reset itself once you make the correction.

Our Buick had the Check Engine light on for over a year, no apparent problems. My daughter left the key on and killed the battery about three weeks ago. Check Engine light has been off since.Quote:

It has reset the computer every time I have done that. Many times the light does not come back on for months.Quote:

I've had them trigger by not having the cap snug enough.Quote:
