The sensor signal voltage should change when the vacuum is applied. Replace for a new one and retest. The Powertrain Control Module grounds the Air pump relay control circuit which energizes the Air pump. However, an oxygen sensor is easy to replace on many cars and is usually detailed in the owner's manual. This should activate the pump. Hope you enjoy your conversion. I am assuming you have located the vacuum controlled valve.
P0411 Engine Diagnostic Code For Bmw Z3 P0411 engine code for Bmw Z3 provides below are generic codes that may not apply to all vehicles. Pull out the seat cushion and pull the carpet and sound dampening mat from the passenger side seat clip. It this large hose is blowing air pull the smaller tube. In any cold climate, especially in climates with higher humidity, this water may be more excessive. Vehicles start on a comparatively rich mixture to allow for smoother running conditions. In later car models, the car's computer can usually keep the vehicle running, but the engine warning light on the dashboard goes on to warn the driver.
It appears that my valve is stuck closed, it has yet to open to my knowledge. Posted on Aug 05, 2009 This is a code related to the air flow from the air pump aka pollution pump into your exhaust system. When the pump kicks in, the O2 sensor voltage should go to less than 125mV. You only need to hold the left odometer reset button while turning the key to position 1 Accessory. Cold start the vehicle and observe the front O2 sensor from the scan tool data stream.
This will change the time. The list of automotive Makes at the right edge of the screen. Hello everyone, I've recently acquired a P0411 secondary air injection system code and have been troubleshooting it. If it's full, check P0411 that the fuel shut-off valve is open and that it is clean. However, if the cutoff valve has vacuum, then turn off the engine and use a vacuum pump to supply vacuum to the cutoff valve and see if it holds a vacuum and if air can flow through when vacuum is applied. Another possibility is that if you have had a valve cover gasket replaced and the tubes are routed in a similar manner to the E39 it is real easy to pinch one with a valve cover I was recently told.
Replace it to fix to problem. Seating in the front is very good. I took it to auto zone so i can get a code and came up with p0411 secondary air injection system incorrect flow detected. Vacuum is then applied to both Air combination valve diaphragms which opens the shut off valves. So you see I am almost a sec slower. Any ideas out there on the subject?? Below is a picture of the actuating shaft that is on the exhaust side of the valve.
This depends heavily on the year of the 325is. The light could mean a costly problem, like a bad catalytic converter, or it could be something minor, like a loose gas cap. Getting ready to dump the Bimmer for a Bemmer if repairs continue draining my bank account. Take out the screws and remove the cap and you will see the top of the fuel tank and the top of the fuel pump… First, centre the steering wheel. The fan definitely blows for about 10 seconds on a cold startup, and the thing sounds like a wicked fast hair dryer.
Any part, circuit, or system referred to in a trouble code must be individually tested to determine if a fault actually exists there or is perhaps elsewhere, indeed often in systems in the vehicle that have nothing to do with the code. Look up the other , please use the search box. I think the sequence is: - valve gets stuck in the open or partly open position instead of closing after 90 secs. If you have any doubt as to repairs on your vehicle, please contact your technician. I checked it out and some wiring got burnt those wired are connected to something but I don't know what exactly maybe the air pump because it gave me that p0411 code.

These valves should flow evenly. I also came up with a home diagnostic situation to prove to anyone that the old one was bad. If your are for a different car, select that vehicle series before searching for the diagnostic codes because not all used by one manufacture are used by the other makes. The vehicle service manual should be consulted for more information on possible causes of the fault, along with required testing. I looked up the part number on the valve and noticed is has changed at some point?? Hope this give you great details about this car. The engine has an A. I took pictures if I can send them so u can look and help me come up with the name of that part so i can buy and fix it asap.
About 90% of the time that this code is set, the one-way check valves have worn out or failed and allow water which occurs naturally in the exhaust back into the pump. If there is vacuum, then you may have a damaged vacuum solenoid. It is either electric or turned by the drive belt. The acceleration is great and for sure enough for daily drive. Once that is done, erase the code and see what happens.
In terms of interior, everything is easy to reach and controls for radio and air-con is simple at least way more simple than Audi A4. The system consists of an air pump, one way check valve and associated pipework. Use the necessary tools to remove the spark plugs. If you have vacuum on this line the valve itself could be bad. I've researched the problem on the other forums, as well as followed the do it yourself troubleshooting from BavAuto. Take the new valve and throw it in the freezer when you get home.
