Failed for HC in new jersey

This measurement is measuring how much raw fuel or hydrocarbons exist in the exhaust.

So, this could be a converter but before we go there, we need to run through these guides and make sure there are no codes and then review the smog test guide as well since NJ is similar to CA.

Next, we are going to have to test the converter to find out if it is reducing the hydrocarbons enough. If the engine is running properly and not misfiring, then more than likely the converter has failed.

This guide will help with this:

I suspect you are correct based on this info, but we need to run through this first and then we can take the next steps.

Thanks
