My car is throwing a p0300 code very often. If I put the creader in does it allow the systems running in the background on the ecu to have "readiness"? In my state for emissions testing, the ecu can have up to one system not "ready". Can I drive around with the creader and allow my ecu to get "ready" and pull the creader out when I get to the emissions station?

 

The CReader also resets freeze frame data, so every system should be "ready" as you say. Of course, the state could say that you have to have a not recently reset MIL, but I don't think that anybody actually does this.

In NM, they simply plug in OBD-II to verify that you don't have any emissions failures. I literally cleared my O2 code while waiting in line to be tested.

I would be very surprised if any state fails you because of the p0300 code. Has it happened to anybody?

If you clear the codes and freeze frame data, several tests may not be ready, typically the catalyst test and the EVAP test, as the conditions have not been met to run them. The car will not pass in Louisiana with more than one readiness code not completed.

Edit: *IF* you can clear the codes, and run the vehicle in such a way as to not set a misfire code while running at a ~60 mph cruise (to run the cat test), you might be able to slide by.

Does the CReader allow you to look at the OBDII Readiness status?

 

Just take all the positive timing out of your maps, run around for a while. Go get tested then put the creader & your old maps back in.

 

Nope. It's a very simple device really. It pulls the codes, displays them 4 times then clears everything. It continues to do this as long as it is plugged in. There is no user intervention. It's not a general purpose scantool.

Here in GA, you can't pass emissions with more than one system not ready, nor can you pass with any type of service engine light. So some of the systems will not have requirements met to be ready if I use the creader?

 

Had this problem myself yesterday... can't pass emissions here with stored/shown codes or not ready reads. If I zero out my added SMART timing, the car runs like ***. Esp on tip in when when one would attempt to drive normally. I'm afraid the tech will not be able to drive the car in the bay.

 

Man, I don't miss emissions testing. You guys seem to have to do quite a bit to get your cars ready for testing...bummer man.

Here in Kentucky and in Ohio emission testing is gone -- bring on the cat-deletes!

 

TN and GA testing are very similar. The easiest thing to do, which I just had to, was simply unplug the XEDE, take out the CReader, and drive about 150 miles. The ECU will then be "ready". You will have no problems passing emissions.


If you simply take out the CReader change adjust your tables, you will most likely still fail the OBD-II scanning. The reason being is that the emissions tester hooks up their computer to your ECU, your ECU will trigger back a "Not Ready" error. Because of that they will most likely fail you and tell you to come back.

Now, I am not sure what it is like in your state, but that is how it is here in TN.

I hate emissions testing. I wish I was back in KY with no VET Testing.

Oh well...I passed this year

 

Actually, I did pass yesterday by just zeroing out the added off boost SMART timing, and unplugging the CREADER. I drove the car for 100miles before the test. The only not ready I had was the evap for some reason. The rest were good to go. Here, I believe you can have up to two "not ready's" and still pass... or one, can't remember

I guess it is still the fact that my tune is off that the car runs so bad at tip in. When I added the timing back in, tip in was not much better than I stated above. Makes for a less than ideal daily driver I still need to get Shiv to fix this tune!

 

That's a bummer Zeus. You still running that white rabbit? I can't recall what all you have on that car -- i'm pretty sure you have run the gauntlet -- cams, turbo, alky, tbe, coilovers, etc...correct?

 

Here in La. having one or two "not ready" monitors is acceptable, but the catalyst monitor must be completed.

The EVAP monitor requires 2 cold-hot-cold cycles in order to complete, so that's probably why yours didn't set.

 

fwiw Readiness monitors require only 15-20 mile trip to set the cat codes and the 2 start cycles for evap.

 

The car had several cycles in that 100 miles... so I'm not sure about that one. Guess it matters not since it got the sticker.
