So my check engine light is on. I reset it & drove a cycle (about 40 miles) & it came back on. I took it to Advanced & this code came up.
P0410:Secondary Air Injection System Malfunction.
Does anyone know what this means or where to start? Anything would be helpful.
Thanks in advance......[

 

P0410 - Secondary Air Injection System

P0410 Explained is the book description and diagnostic flow, but that isn't for everyone... Read through it and if you have any questions, please do not hesitate to ask.

 

ok guys i didn't want to start another thread on this code cause there are a bunch already i have the troublesome p0410 code being thrown on my 2001 blazer Lt 4x4. i pulled the pump off and bench tested it, it kicked and and was working. i check the two fuses and they are both fine, i checked the hoses and they seem free from any cracks or clogs. could it be possible that there is a break in the electrical wiring or anything else i may have missed?

and i have been looking into the blackbear performance tuning and also wait4me performance tuning any ideas on wheather these are good options to also have to code removed by getting a tuned pcm? and does anyone have any experience with either of these companies?

thanks in advanced
