Inspection failure

Do you have an obd adapter and Android by any chance?

I believe it was the "obd auto doctor" that I used that let me see which monitors were set yet.

 

i would do a combo back road/highway before the inspection.

 

Each monitor that is "not ready" has a specific "confirmation driving pattern" that is the fastest way to get it to complete. Often people don't want to bother with that level of detail, and just do enough miles of enough different kinds of driving and hope all the monitors complete. Which is great, if you have time for that.

But for certain monitors it can be way faster to follow the specific confirmation pattern, if you are under time pressure. For example, the EGR monitor only needs to find a five-second or longer period of fuel-cut deceleration from a moderate speed with the engine warm; those are the conditions where it can sneak in the EGR test. (See the confirmation pattern in the repair manual for the full details.) Doesn't take nearly as long as driving 200 miles and hoping. And similarly for the other monitors.

All the confirmation patterns are in the repair manual. Each pattern is given under the diagnostic trouble code that would be set if the test failed. (That kind of makes sense, even though when you're just waiting for a monitor to complete, nothing has failed yet, so you don't have any code.)

So, you can turn to the P0401 code to find the confirmation pattern for the EGR monitor. Likewise, you can turn to the P0420 code to find the confirmation pattern for the catalyst monitor. The O2 and heated O2 monitors will also have confirmation patterns that you can find under whatever the trouble codes would be for a failed O2 or heated O2 sensor test (I don't happen to have those codes memorized; they'd just have to be looked up).

 

Yeah, it shouldn't take hundreds of miles at all.

 

congrats!
