I'm looking for emissions advice. (2002 3.8l V6 Mustang, STOCK) I was pulling a P1151 AND P1152 so I replaced the O2 sensor accordingly and this fixed the problem I'm assuming since I'm not pulling these codes after driving 150 miles. The day I replaced the O2 sensor I drove about 55 miles thinking I'd be good to pass emissions if I drove 50 miles with no code. I received "Not Ready" status from the emissions place (which I was afraid of) since I had cleared the codes after replacing the sensor. The next day I drove it up to 115 miles so I had driven the car 115 miles since I cleared the codes with my OBD. Went to emissions thinking there was no possible way that I didn't complete the drive cycle. Turns out I received "Not Ready" again and thought to myself: "Okay, I'll just go back tomorrow after I've driven it 150 miles and there's no chance I will get a "not ready" status." Went back the next day, and got an "Excessive Unreadiness" result. This was because I had already gone in twice and recieved a "Not Ready" status and my vehicle was set as an excessively unready vehicle after two attempts recieving not ready. (I didn't know thats how it worked.) After that, they tell me I need to bring it into a shop and have them run an OBD test and then have the mechanic call the ADEQ (Arizona Department of Enviornmental Quality) with the "Readiness Monitor Status" in order to clear my vehicle for another emissions test. MY QUESTIONS IS: Since I have my own $200 OBD2 tester, am I able to call them myself with my cars status? If so, what exactly is "Readiness Monitor Status"? And where do I go from here? Any help appreciated.
