I have a Chevy 2009 HHR and I went to have the emissions tested today and it was rejected. I turns out that I have to drive the car everyday for a week to get the computer to reset or do the tests and then I have to have it tested again. Does anyone know how much I have to drive the car each day? I had the car sitting for a long time and ran the car for about 10 minutes twice a week to keep the battery charged.

 

Drive cycle information, I’d drive it at least 30 miles round trip, get the coolant warm and flowing, the catalytic converter heated and the O2 sensors working.

What specific tests were "not ready"? Any check engine light.

I wonder how may states have a College Park.

 

Different vehicles have different "drive cycles", sometimes even different between different years of the same model. A drive cycle that you find on the internet for Chevrolet, will probably be incorrect. Completing this necessary drive cycle can be difficult and frustrating, because you can't know exactly what to do!

Take the freeway(when traffic is light) to a town at least 20 miles away, drive around town a bit, then back on the freeway to your town.

Don't clear check engine lights, don't disconnect the battery, or you'll be starting from square one again.

 

No check engine light, but the SVC tire monitor comes on. Maybe the tires are low on air. A pic of my HHR is attached.

 

What state are you in?

In New York State only an illuminated MIL light or a readiness monitor not ready will fail the emissions inspection.

The SVC tire pressure monitor doesn't have anything to do with inspection. Also ABS faults won't fail inspection.

I forgot to mention, if it says SVC tire monitor, it means there is a problem with the monitoring system (battery dead in tire unit, receiver bad, etc). If a tire is low a different message is displayed, "check tire pressure" (I think).

In any case, scroll through the DIC displays until you see the tire pressures for the 4 tires. If there are any dashes instead of a reading, that sending unit is not working. If all are dashes, that could mean a bad receiver or all 4 sending units are bad( dead battery usually).

 

I included that link, it’s from Donbrew back in 2014, about specific GM drive cycle information.

 

How do I scroll through the DIC unit? I recently got the HHR and haven't figured everything out yet.

 

Since you ignored my first question I will risk answering yours and ask again; what specific test is not ready; it makes a difference how long it takes..
