I replaced my head gasket on my 2000 528i BMW. Now that I am finished the car runs great. I didn't have any codes when I started the job but now I have P0412 code and a CEL. Secondary air valve...


Good evening Daniel,
Congrats on replacing the head gasket successfully! In regards to your secondary air system. I would first start with the electrical air pump supply located on the passengers side of the engine compartment. You can locate the supply hose (about 1 1/2 inch diameter) at the front of the exhaust manifold. The hose connects to the secondary air valve. Make sure the hose is connected. Also make sure if there is a vacuum supply line to the secondary air valve, that it is not broken/or disconnected. If the hoses are ok and secure, then remove the larger supply hose from the valve when the engine has not been started for 4-5 hrs and make sure you have air flow from the air pump. The pump should be audible and operate for approximately 30seconds to a minute. If you are still having issues after these checks, I can list other possible causes.

NEED DRIVE CYCLE FOR 2004 CRV TO RESET CAT AND O2 MONOTOR


Here is the info

NOTE: The ignition key must not be on prior to the cold start otherwise the heated oxygen sensor diagnostic may not run.

1. As soon as the engine starts, idle the engine in drive for two and a half minutes with the A/C and rear defrost on. OBDII checks oxygen sensor heater circuits, air pump and EVAP purge.

2. Turn the A/C and rear defrost off, and accelerate to 55 mph at half throttle. OBDII checks for ignition misfire, fuel trim and canister purge.

3. Hold at a steady state speed of 55 mph for three minutes.

OBDII monitors EGR, air pump, O2 sensors and canister purge.

4. Decelerate (coast down) to 20 mph without braking or depressing the clutch. OBDII checks EGR and purge functions.

5. Accelerate back to 55 to 60 mph at half throttle. OBDII checks misfire, fuel trim and purge again.

6. Hold at a steady speed of 55 to 60 mph for five minutes.

OBDII monitors catalytic converter efficiency, misfire, EGR, fuel trim, oxygen sensors and purge functions.

7. Decelerate (coast down) to a stop without braking. OBDII makes a final check of EGR and canister purge.

Engine light on . fault code p0411. air solenoid stuck shut. show


P0411 Secondary Air Injection System Incorrect Flow Detected
p0411 is a generic code, probably a vacume leak,vacume hose broken check this first, check the air pump turn on the car but it needs to be cold, you should hear a high pitched whine, this is the air pump running,there are 2 hoses one suction one blowing thishose should be going from the air pump to the air cleaner disconnect that and see what the volume is should be pretty strong.
But mostly you probably have a broken vacume line somewhere

Diagnostic code 410


PO410, Secondary Air System Performance

Possible Causes:

AIR solenoid power circuit is open (check the U/H IGN fuse)
AIR pump is damaged or has failed (inspect air pump for water)
AIR system check valves and/or pipes are damaged or leaking
AIR system hoses or lines are damaged, pinched or kinked
Base engine problem (e.g., excessive exhaust back pressure)
PCM has failed

The pump is up near the radiator, common problem.
