Check the battery cables making sure they are clean and tight. Have the batteries checked. Change both batteries at the same time if you don't the older one will pull down the new one and make it go bad quicker.

My batteries were low on water so the voltage was low and it keep throwing p2509. Its gone now.

How many miles does it take for a service engine light to reset? I had the light come on and went to my local auto parts store for a free diognostic test, they told me that the upstream O2 sensor was bad....

Nothing to do with miles

If the new sensor was the correct fix, then the light would be off

Maybe the light will go off when the Emissions Monitor Runs,
but doubt it,you went 4 miles & the O2 Data has to be working

You DO NOT Replace parts based on a code
Codes have nothing to do with parts

Codes only indicate an out of range parameter or possible fault

You use the codes to component test the system, that set them
Find a fault or problems
Make the repairs, if necessary

You had no diagnostic test
You had it checked for generic codes only

You have to component test all old & new parts,not
just hang them on there, because of some one is selling
parts with no vehicle knowledge

P0420 error code

The fault code P0420 is caused by the catalytic converter falling below minimum efficiency level as measured by the catalytic converter monitor sensor (similar to an O2 sensor, but different function). The cat is not covered for 120,000 miles. Here is the correct information on the warranty of the catalytic converter.
The Federal Emission Warranty covers that part for a period of 8 years or 80,000 miles, whichever occurs first. So you are out by years in service and by miles.

2000 E-350 V-10. P0174 with exhaust fix

Before I even finished reading this i knew you had a clogged cat. If you have fixed everything you mentioned i would lean towards a clogged cat. This is a large reason this code pops up.

To check this you could pull that cat out and drive around and see if the code comes back, make sure to stay away from the police though.

Check engine light is on. Runs rough. Read codes???

It may be a plugged Cat Converter. They usually plug up at about that many miles. The check engine light will come on when that happens.
Try going to a auto parts store. They usually have a code checker to discover the problem in order to sell the parts to fix it. Try that first.

Check engine light is on, we had it fixed but 100 miles later it went on again

had my check engine light cleared to get it smoged. was told by smog company that the panels take 100 miles to reset. seems that the fix was not really a fix after all. they must have cleared the code and it took your computer the 100 miles to identify the same problem your mechanic was supposed to fix, but didn't. good luck fighting the same thing.

Code p0455 evap emission (large)

have the gas cap tested or just replace it, then disconnect the battery for 5 minutes to reset the code, then drive it for a few miles and see if problem comes back, if it does a trip to the dealer is in order, as this may be covered by your emission warranty which is good for 70,000 miles.

2002 Sable LS 43,000 miles. Check Engine light on again!

without a fault code its impossible to diagnose. try pep boys or aamco or auto zone they will pull the code for you, usually for free. The code will relate to a sensor or area to be fixed. This will save you money and needless parts . post the code or codes so we can help
