Celica Forums General Discussion Engine and Performance CEL light problem: P0416

has anybody had this?
fault description:
"Secondary Air Injection System Switching Valve "B" Circuit Open"

all i have on is an Injen short ram and Blitz exhaust

thanks

how long have you had the injen system on?

had the injen on for quite some time before it came on, so i can't see it being this.

have had it before and after exhaust fitting

weird thing is i reset the CEL and it can turn on next time i start the car, or it may come on after several hundred miles or just a few trips. so it's random, not like it comes back straight away after reset

I am also having a similar problem. I put on a short ram and am throwing a CEL saying front o2 is bad. But when I reset it it comes on with in atleast 12 hours. Why? also, i have a low idle and it boggs when i floor it to WOT. help please.
