ses light

[TJKIDD]

Yeah my 99 camaro z28 ses light came on and these codes popped up.

P0412-secondary air injection switching valve A circuit

P0410 secondary air injection system

p0418-secondary air injection system relay A control circuit

Yea so i have changed everything on this car plugs,wires,o2,heders. I'm thinking this is caused by the mass air flow sensor???? (i havent cleaned it yet) But still not sure what do yall think? And if its not should i just tune it out? By the way this is my first camaro so i'm still new to this car.

You can buy a can of maf cleaner, all you do is spray the wires on the inside down really good and let it sit out and dry. Are you using any kind of k&n filter cause the oil from the filter will get on your MAF sensor and make it throw a code!! And if you are using that filter it's better to use a paper filter!!

Ok so do i have to take it apart or just spray the outside of it? and yes i'm using a k&n filter, do i need to clean that to just to clean the oil up??? And paper filter???? Sry i'm not that knowledge able the air system

Everybody on here will tell you to get rid of the k&n filter get a regular paper filter I have heard amsoil is one of the best. And yes take the mass air flow sensor completely off when you do it spray the wires on the inside of it. Miswell descreen the sensor also just don't mess with them wires or you will have to buy a new one.

Ok thanks Bluehawk, hope this will take away the ses light cause it getting on my nerves.

Yea no problem and it kills your gas mileage also when the ses light is on computer is trying to adjust to the readings.

You just need to get the whole intire AIR system tuned out.
im pretty sure these codes you have, have nothing to do with your MAF

Exactly right. Those codes are caused by the air pump. Time to remove it.
