P1412 & P1415

Read about the sai, I didn't think it came on when the ambient temp was that high.

I think rave says p1412 and p1415 could be electrical. I am not sure which relay it is to check. I have also read that the valves stick which results in these codes because of no flow to exhaust.

Yeah I believe its only supposed to come on at 68 or below which is pretty odd why it has been coming on with temps we have in FL. It even came on one time at a stop light and triggered the same codes.

the vacuum harness can leak without looking like it.. and the solenoid can go out. I would replace at least the harness and then go from there. the valves dont fail very often. mostly from running it with a bad blower motor, so exhaust gasses flow backwards into it.

Ill give this a whirl, I need to order a few other things for the ole girl, might as well throw this in as well. Would Brit Atl have this. I know its no biggie, I just cant stand seeing that dang check engine light come on every other day.

mine does that from time to time, will come on randomly during a drive when I am idle at a light, almost feel the surge in power.

I think it has more to do with electrics or sensors than anything honestly. I suck at electrical stuff so I don't even know where to go.

it comes on anytime the engine is started at 120* or below, and if the ECU deems it necessary.

If it is coming on when you are driving it, then something is seriously messed up with your ECM... there isnt really any sensors that go with it other than the O2 sensors....

replaced the vacuum solenoid for the second time for this issue and finally have a winner! No more P1412 & P1415 combo. No more random blower coming on at stop lights, etc.
