Hello everyone I just installed a used Wizair intake with a spectre cone filter. Now I keep getting a code 0411. I had the open cone on it for a while with no problem. I had to reconfigure the setup to fit the air box now I'm getting the code. I have the filter attached to the
(I think its the MAF the part with the screen in it and has the plug on it). Any help would be great. My car is an 05 na gt. Thanks John

DTC P0411

•Secondary Air Injection (AIR) System Insufficient Air Flow Detected

The secondary air injection (AIR) system aids in the reduction of hydrocarbon emissions during a cold start. The system forces fresh filtered air into the exhaust stream in order to accelerate the catalyst operation. An electric air pump, the secondary AIR injection pump, provides filtered air on demand to the AIR control solenoid valve/pressure sensor assembly. The AIR control solenoid valve/pressure sensor assembly controls the flow of air from the AIR pump to the exhaust manifold. The AIR valve relay supplies the current needed to operate the AIR control solenoid valve/pressure sensor assembly. A pressure sensor is used to monitor the air flow from the AIR pump. The powertrain control module (PCM) supplies the internal pressure sensor with a 5-volt reference, an electrical ground, and a signal circuit.

The AIR diagnostic uses 3 phases to test the AIR system:


1.DTCs P0411 and P2430 run during Phase 1
2.DTCs P2430 and P2440 run during Phase 2
3.DTC P2444 runs during Phase 3

During phase 1, both the AIR pump and the solenoid valve are activated. Normal secondary air function occurs. Expected system pressure is 8-10 kPa above BARO.

During phase 2, only the AIR pump is activated. The solenoid valve is closed. Pressure sensor performance and solenoid valve deactivation are tested. Expected system pressure is approximately 15-20 kPa above BARO.

During phase 3, neither the AIR pump nor the solenoid valve is activated. AIR pump deactivation is tested. Expected system pressure equals BARO.

In all 3 phases, testing is accomplished by comparing the measured pressure against the expected pressure. The PCM can detect faults in the AIR pump, AIR control solenoid valve/pressure sensor assembly, and the exhaust check valve. The pressure sensor can also detect leaks and restrictions in the secondary AIR system plumbing.

recheck every connection under your hood thorughly

I have noticed that the car is not sucking in that first burst of air at the start.

recheck all of your connections under the hood thoroughly

is it a california emissions car

no the car is from ct. I am going to check evrything tomorrow.

Odd if your car isn't originally a Cali car. The SAI is an actual electronic pump that sits by the transmission and has a hose which goes from airbox and dumps it into the exhaust to create a "lean" reading thus causing the injectors to dump more fuel and therefore heating up the cat faster. It has nothing to do with the actual "sucking" of the engine itself.

If you have the intake hooked up right, I'd just unplug the negative terminal on the battery for 10+ minutes and see if the codes goes away. If your car isn't a Cali car (i.e. doesn't have a big black electronic pump sitting in front of the transmission with 2 black hoses coming out of it, see pic) then that code shouldn't even be popping up.

I do have that pump so is my car a california car?
I took the whole intake setup apart today and put everything back. I cleared the code and hopfully it does not come back.
Thanks for the help

yup your car would be a cali car. the 01 had the same thing

it was a 50 state leagal car though being a rental. it came from arizona

Learn somthing new everyday. I,m pretty sure the car was sold new in Ct. Go figure .
Thanks for the info.
I think the problem might have been the insulation from the air box blocking the hose for that pump.

What you can do is put a little breather filters on the end of that hose. That way you don't have to do anything funky with your intake but will still have a functioning SAI system.

Is that what the rpo's say?

Mine is a Florida car with cali emissions

Thanks to everyone. I fixed the problem and I found out my car was a Cali emission car.

Can you just remove the air pump and clear the codes?

^^^ if you blocked off the port on the crossover it looks like?

so this looks like a secondary egr???

_________________

It's not a secondary EGR since it doesn't send exhaust gas back into the intake, it's just to pumps fresh air (thus more oxygen) straight into the exhaust manifold during cold starts (usually only for 30 seconds or so on most cars with them) to give the o2 sensor a lean code so it richens the AFR which then heats the cat up faster. The only thing this system is good for is throwing a CEL, see sig pic
The irony that this sort of "emissions" system uses more fuel in order to make less CO2 come out the exhaust tip. Seems bassakwards to me.

on the 01 it pumped the air into the down pipe. the cross over was the same as a fedral car
