Not definitive but it sounded like CA state law.. to prevent people from resetting the warning and pass the smog test.
Well...maybe yes and no...
Clearing a code(or multiple codes) also clears emissions monitors....which in itself will fail an emissions test
anywhere, not just Callyfornya. The vehicle would then need to complete a "drive cycle test" before the emissions related monitors would pass. Drive cycle procedures are different for every manufacturer, so there's no one way to get them to complete....you just have to drive them the way the manufacturer states to get all of the monitor tests to run, and pass. Sometimes you can just drive the car for a few days normally, and sometimes it may take a month before all of the tests will run. On OBDII cars('96 & up), testing stations plug into the vehicle diagnostic port, and the vehicle's PCM will tell the station whether or not ALL of the tests have run, and whether or not they passed or failed. If they have all run and passed, then they will do the complete inspection. If not, then they will stop right there, and fail the vehicle.
It is LEGAL for ANYONE to purchase and use an OBDII scanner/code reader, so there's no fear of buying one yourself, and checking your own vehicle for codes. There are many reasonably priced code readers out there, depending on how sophisticated you want it to be. You can clear codes yourself if you want, but if you have a state inspection due, you'll have to find out the
manufacturer's specific drive cycle procedure, and try to get the tests to run and pass before inspection time. On Fords, anytime the codes are cleared, it sets a "P1000" code, meaning codes AND emissions related data have been erased, and the drive cycle has not been done/completed("OBDII tests not run"). Once the drive cycle has been completed, the PCM will clear that code, and the vehicle will be ready for inspection....assuming no other emissions related codes set in the meantime.
As far as Autozone/Pepgurls not being able to scan for codes, that would have to be a Calli deal....I've never heard of it. Why would AAMCO be able to do it, but not the parts place? Prolly because an auto repair shop has the ability to
repair the vehicle....autozone can't.
hth :mrgreen:
I'll see if I can get the procedure for a 2011 E-150....

The following procedure is designed to execute and complete the OBD monitors. To complete a specific monitor for repair verification, follow steps 1 through 4, then continue with the step described by the appropriate monitor found under the OBD Monitor Exercised column. For the EVAP monitor to run, the ambient air temperature must be between 4.4 to 37.8°C (40 to 100°F), and the altitude below 2,438 meters (8,000 feet). If the OBD monitors must be completed in these conditions, the powertrain control module (PCM) must detect them once (twice on some applications) before the EVAP monitor can be bypassed and OBD monitors readied. The EVAP bypassing procedure is described in the following drive cycle.
The OBD drive cycle is carried out using a scan tool. Refer to the manufacturer's instruction manual for each described function.
A detailed description for clearing the diagnostic trouble codes (DTCs) is found. Refer to Clear The Continuous Diagnostic Trouble Codes (DTCs) And Reset The Emission Monitors Information in The Powertrain Control Module (PCM). See: Reading and Clearing Diagnostic Trouble Codes\Clearing Diagnostic Trouble Codes / With Manufacturer's Scan Tool\Clear the Continuous Diagnostic Trouble Codes (DTCs) and Reset the Emission Monitors Information in the Powertrain Control Modu
Drive Cycle Recommendations
WARNING: Strict observance of posted speed limits and attention to driving conditions are mandatory when proceeding through the following drive cycles. Failure to follow these instructions may result in personal injury.
1.Most OBD monitors complete more readily using a steady foot driving style during cruise or acceleration modes. Operating the throttle in a smooth fashion minimizes the time required for monitor completion.
2.The fuel tank level should be between 1/2 and 3/4 full with 3/4 full being the most desirable.
3.The evaporative monitor can operate only during the first 30 minutes of engine operation. When executing the procedure for this monitor, stay in part throttle mode and drive in a smooth fashion to minimize fuel slosh.
4.When bypassing the EVAP engine soak times, the PCM must remain powered (key ON) after clearing the continuous DTCs and relearning emission diagnostic information.
For best results, follow each of the following steps as accurately as possible:
