Failed smog test twice

Hi,

So if the check engine light does not come on at all then it is not running the self check which means if is most likely failing the self check.

We need to hook up a scan tool and see if there are any codes and go from there. Unfortunately, the previous issue of the leaky hose is a different issue.

Let me know if there are codes and we can go from there. Thanks

Sounds good.

In order to clear codes on this vehicle with a scan tool they just need to select the option on the scan tool of "clear codes" and the tool will do it.

This is not required when there are codes in the system because they are either Active or Stored. When they are Active that means the issue is currently happening which means it is currently "broken."

When the codes are stored however, this means the issue is not currently happening and the computer just holds them for a specific amount of time so that a mechanic can reference what happened if the customer does not bring the vehicle in while the issue is happening. This gives them a better chance at seeing what happened and fixing it. If they don't clear these and reset the computer then leaving stored codes in the system is harmless.

Its like leaving your book mark in a book when you return it to the library. Others can see where you were but its not going to hurt the book. Sorry for the analogy.

Plus not doing this is not going to cause the check engine light to not come on during the self test.

One more question. Can you get a video of the cluster when you are starting the vehicle? This will help ensure we are on the same page.

Then let's see what the codes are and if the reader can communicate with the PCM and go from there. Thanks
