Hi everyone,

My engine light came on last week, and so I took it down to Autozone to check it out. They said it was the MAF sensor. They suggested I buy a can of this spray cleaner to see if that fixes it. I cleaned and reinstalled, but nothing changed. I went back in and bough the new sensor. It's only $35 and a two minute fix, and that still didn't kick the engine light off. I haven't really noticed any engine sounds or loss of performance as I've read about here in the forum. The light still reads a problem with the sensor, so I'm concerned about ignoring it.

Can I just have Autozone reset it and see if it pops up again? Any other ideas? Thanks, guys.

If it was not reset then yes have them reset it. If it comes on again then there is another issue.

Good luck,

And if replacing the MAF did fix it the light will go off on it's own after several driving cycles. The code will still be stored unless you erase it.

 

I guess my concern is that I left the negative battery unhooked for a few hours in hopes of the computer resetting itself...and it didn't. I'll give it another day or two to see what it will do on its own. Crossing my fingers it's nothing more than this.

 

Don't think Autozone will reset it. They will only read codes--not reset them. At least that is the way it is in Maine and New Hampshire. What exactly was the code?

 

There are 2. P0171 and P0174. I done a lotta reading, and I checked all the basic obvious problems. All hoses are connected and seated properly. I'm stumped this point. It drives just fine, but I can't get her that silly error code.
