Default Checking codes

Hey, my friend recently got a 2000 SE. His check engine light is on and I'm trying to figure out how to retrieve the codes. I've tried searching this forum, but I can't seem to find the actual method.

The easiest way is to take it to an Autoparts store that reads them for free. I know for sure AutoZone, Advance Auto, and Parts America all do this for free.

Otherwise, you'll need to buy a code reader if you wish to do it yourself. The car is ODBII

There'* a diagnostic port at the bottom of the dash below the stearing wheel for plugging a code scanner into.

correct, the only way to retrieve the codes with either a code reader or a scan tool, many major parts stores will read them for you for free

come back and let us know what you find

Well we had it checked out last week at Autozone and they said there'* a lean condition in bank one.

The guy suggested bad gas but I'm not so sure about that...if the gas really was bad the problem wouldn't be localized in bank one.

At this point I'm thinking intake leak...anybody have any ideas?

And also, for reference...which bank is bank one?

You have two O2 sensors. The one in your rear manifold watches all 6 cylinders. The one after the cat is only for emissions.

Can you please verify that the O2 sensor harness isn't in contact with any of the rear plug wires?

From there, we need to determine if you have good fuel pressure and how old your O2 sensor may be.

I'll move this topic to the right section for you.

A lean bank one code should never be confused with a bad O2. It'* possibly caused by a bad MAF, however that is infrequent. The largest single cause in the past year is battery connection related.

San Juan Cruiser had a bad battery post causing a poor connection, and I had badly corroded battery cables.
