P0410 and P1411

Recommended Posts

Ok, In the past I was getting the P1411 code ONLY. Its was only Intermitent and after I cleared the code from the ECU, it would take about a month to come back. Now I got both P0410 and P1411 which are Secondary Air Injection Cylindars 1-3 and 4-6.

I've heard that the air injection system is under the intake plenum which makes it alittle back breaking and difficult to diagnose the exact culprit in the air injection system. Could someone here give me some steps in pin pointing the cause of these Pcodes so i dont buy parts i dont really need?

Thanks in advance!
