[font=Verdana, Arial, Tahoma, Calibri, Geneva, sans-serif;font-size:13px]When I start the old '07 H3 I get engine code P2431 which says "Secondary Air Injection System Pressure Sensor Performance."  Apparently this reduces the hydrocarbon emissions during cold starts??  Really other than the light coming on and I turning it off with the code reader every time the vehicle doesn't drive or run any different at all, a few weeks ago it breezed through an Ontario emission test.[/font]

[font=Verdana, Arial, Tahoma, Calibri, Geneva, sans-serif;font-size:13px]Do you think it's worth looking into or not a big deal?[/font]

[font=Verdana, Arial, Tahoma, Calibri, Geneva, sans-serif;font-size:13px]Thanks[/font]

Eventually you will have to get it fixed for the next e-test so I guess it's a matter of how long you want to wait to fix the problem.
