Service Engine Soon light came on last Monday with just over 70k on it.

At last service Air Filter was noted to be dirty, so maybe that's it.

However, I hooked up a Actron OBD II Diagnostic Tester - CP9035

It didn't pull any codes at all, IE, it returned a 0 ZERO

the light is still on, and I didn't want to erase it just in case there is a TSB out on the car that is the reason for the SERVICE ENGINE SOON.

I know my scanner works, just used it recently. It passes it's self diagnostic and does pull codes from my Fords and other vehicles..

Getting a Actron ScanTool - CP9110
with Ford, GM, Chrysler and a OBD II cartridge next week.

That will help scan the computer and monitor in real time.

If not, it goes in the shop Wednesday. Anyone else experience this?
