Accessport Emissions
Hey guys,
I was under the impression that the accessport puts everything into the "ready" state when you flash your ecu to a STG2 but today when I went to get my car inspected for emissions, the computer came out with readings of Not ready for the Catalyst and the O2 Sensor. This would make sense if i recently reflashed my ecu or dissconnected my battery but the last time i've done that was maybe 10k miles ago... Anyone know what the problem might be? Also does anyone know if pulling codes from places like auto zone will render the ecu status's to be not ready ?

The monitors need to be up and running for the machine to test i.e O2 Sensors. If the car was just flashed, battery disconnected for any reason, all monitors are blownout. CEL cleared? Same thing. The Fix - The car needs to be driven about 3-4 miles without being beaten and then left to idle a couple minutes. Usually gets them back up and monitoring again. Your Stage 2 Cobb flash should be fine - see them all the time Hope this helps! tristan |

oops should have read all the way -- so you know what im talking about - but i do believe a pull at AutoZone depending on the type of scan tool it is could blow out the monitors.... (sorry being an idiot and not reading all the way)

also did you clear a code if pulled by AutoZone? That will do it to...

same thing
Hi
I've had the same experience. And have been posting on the COBB forum. http://www.cobbforums.com/forums/showthread.php?t=37307 Prior to my 1st attempt at emissions, the last battery disconnect was 3000 miles prior. Since being Rejected ("Not Ready") I've: 1) Updated maps 2) Updated accessport manager 3) Gotten the ECU identifier's to match the actual ECU 4) Unmarried 5) Remarried 6) Reflashed Base map 93 Stage 2 7) Done 280 miles of mixed driving 8) Retested at emissions 9) Gotten "Not Ready" for a. Catalyst Efficiency Status b. Oxygen Sensor System Status c. Heated Oxygen Sensor System Status The only thing that was "Ready" is Evaporative System Status. So yea. I've got no advice, just want you to know you're not alone. |

well you were going to fail anyway with a CEL, im going to check my monitor status tomoz and see, the evap will deff be ok but the other guy has a point of catalyst... how could it show an efficient cat if there isnt one? lol the 02 readings would be identical...

Dooley:
Which codes are you getting as "Ready"? I only have 1 working. I just posted up my report on my thread on the COBB site (it's on the 1st page of my thread). http://www.cobbforums.com/forums/showthread.php?t=37307 yes, this is the suck... |

this is what is happening with me
Misfire - R Fuel System - R Component - R Catalust - N Heated Catalyst - U Evaporative System - R Sec. Air System - U A/C System - U O2 Sensor - N HO2 Sensor - R EGR System - U |

Do you have a mechanical fix in place for the O2 sensor? Although the Cobb maps will defeat the CEL, you'll still read as "not ready". This is why its a good idea to still go ahead with the mechanical (spark plug anti foulers) for the rear O2 as well as the resistor fix for the uppipe EGT if you have that unplugged. That way even if you unmarried the AP completely, you'd still be ready. Your situation is different from the usual not enough miles since ECU reset problem.

that was my question as well for you. sometimes the CEL fixes do not allow the system to go into a readiness state.

Hi Dooley,
Any luck with this yet? I haven't had a chance to change anything. Spark plug anti-foulers as an O2 fix? I haven't heard of that before. |

To get all the emissions flags to set (ready) I know the car may have to be started cold(overnight sit) then driven for 30 to 45 min at different speeds to set all the emissions flags. Here is my question. With stage 2 is the post cat oxygen sensor always going to be in not ready mode? I know in Indiana the car will pass with all but one emissions flag read, some cars older than 2000
you can get away with two emissions flags not setting. I don't have to worry about this until next year but I like to plan ahead. I work for an emissions certified Cadillac dealer and deal with this all time, but I dont have any Cadillac owners that have removed their cats and reflashed their ecm. |

so after driving my car for about two weeks (should have been more than enough driving) I went to get emissions tested and the results came out to be the same,
O2 and Catalyst N (not ready) I bought AP years ago cause they had told me it will pass emissions by making those sensors in READY state.. now i have to deal with this crap. |

Dooley, do the mechanical rear o2 fix.

If you dont want to deal with the antifoulers, then buy something like this:

The AP should not be causing any OBD2 readiness states to be not ready. That is not how the AP works. I think you may have an unrelated problem, such as a broken O2 sensor or wire. It could also be that your ECU is losing power when the vehicle is off, however, you'd probably get alot more not ready states, if that were the case. I know you have stage 2 hardware, but if you go back to stock and run that for a while, I would be willing to bet you would have the same problem.

Are there no codes present at all? Some monitors won't run if there are certain codes present. That's true with most vehicles anyway, I don't really know for sure with Subarus.

I have not tried to get inspected here in NY. But I am running stage 2 map with helix catted downpipe no 02 fix / fouler. NO CEL issues. I hope when I do have to get my inspection done my car will pass hopefully.

Why not just flash back to stock and use the resistor CEL fix for the cats?

did I read correctly that BOTH your o2 sensors (up and downpipe) are not plugged in??
Did you ever consider that to be the problem? |

Perhaps I missed that earlier. If the O2 sensors are just outright missing, the OBD2 readiness states won't ever be set. The AP maps can limit what will trigger a CEL, but the sensors need to complete the circuit for the readiness monitors to run. Also, running w/o O2 sensors is a bad thing. I didn't go back to read, but if you have a cat w/o an O2 sensor, you will poison it quickly. Even if you don't have a cat, the system runs on a feedback loop to hit the proper fueling targets. W/o the sensor, you will always be off.
