SOURCE: Code P0411 is showing Secondary Air Flow problem

The P0411 code you are getting with that SAAB is the SECONDARY AIR INJECTION CHECKVALVE 95% of the time. This sometimes will allow condensation to build up in the air lines
that run to the air pump and air filter. Its part of the emmisions BS that they put on these cars. The check valve is costly, its usually about $100 or more depending on where you live I guess but its
much cheaper than $600+ dollars plus labor for a new air pump.

In some uncommon instances this may not be the problem, but this is a known issue with the SAAB Q93 and some other models. Once replaced it should be ok for another 100,000 miles +/-.

Hope this helps as late as I am finding your issue!

SOURCE: I have a 2002 Audi A4 1.8T with trouble code P0411

I have a 2000 Passat (1.8T), and I recently had this code (P0411). First thing I did was to clean the mass airflow sensor (MAF) and reset the code by disconnecting the battery. Unfortunately, the code came back. It also came back with P1426. It ended up being the purge valve ($60 at ECSTuning, $140 at the dealer...I went with ECSTuning). Before you drop money on the part, inspect all of the hoses to ensure they are not cracked or torn.

Where is mass air flow senser on a 1989 buick regal


Hi

Thanks for using FixYa. The BUICK Regal Mass Air Flow sensor is usually installed in the intake air duct between the air filter and the throttle body mounted on the intake manifold. Also check the throttle body for mass air flow sensors location.
On mass air flow sensors with a sense wire, this wire can become contaminated with dust particles. These particles can be removed with automotive solvents that are safe for the use on mass air flow sensors. Before replacing the mass air flow sensor check for air leaks in the connecting air ducts and intake manifold. These leaks can cause similar symptoms as a malfunctioning mass air flow sensor.

Bad or contaminated BUICK Regal Mass Air Flow sensor can possibly cause a wide range of various vehicle drivability problems such as stalling, especially when the engine is cold, misfiring, poor acceleration, etc. In addition, a problem with the Mass Air Flow sensor often causes the "check engine" or "service engine soon" light in the vehicle instrument panel to illuminate.

Please do accept the solution if the issue is resolved or else revert for further assistance.

Thanks
Rylee

99 buick regal 3.8 starts for 3 seconds and shuts down,


Had the same problem drove me nuts until I tried disconnecting Mass Air Flow Sensor, the car should drive normally but with a "Service Engine Soon Light" on. Mass air flow can run from $140 up, picked one up at recycler for $40.

Worth a try.
