It is on top of the throttle body,
Get the ecu codes read, there is a fault code listed in the engine ecu
all ecu codes are posted at mx6.com and probetalk.com
ECU has registered a fault. Get the codes read to find out what it is.
you need to do an ecu reset...disconnect battey for 1 hour, reconnect, start and leave ticking over for 5 mins turn off, turn on drive it like you stole it for a few miled and this should reset the maf sensor and ecu.

contrary to belief people and alfa themselves will tell you if you have lost all keys you will need new ecu and all that milarky but you don't..take out your boot lock ..and the..code box and you can get a new key coded to the box itself wont cost more than 200 and youl get 3 keys made i got my 156 and bravo hgt done by Steve guard autolocks in dublin awhile ago great service alfa told me it could not be done and gave me a price of 1000 for new ecu , ignition coil etc but he did it in a day and for a fraction of the price...
Some Haynes manuals have ECU codes
Assuming you mean the engine ECU, the answer is no
It means you need to hook up to a computer with the Volvo software and pull codes.
Maybe you have to check the A/C Ecu located in the engine bay.
i dont see why not, my 87 Z31 is running with a 86 ECU (figuring by the codes iv pulled so far are all 86 codes) my car is a 4/87
I will try to answer this. If you mean codes in the on board computer, it takes 100 miles of driving to make the computer readable if the battery has been disconnected for some time or the error codes have been erased from the ECU (computer).
A VW golf as an ECU fuse which is located inside the engine compartment fuse box. The fuse will be labeled ECU. Pull the fuse and the computer will reset all engine codes.
ecu? Do you mean ecm, Engine Control Module?
AnswerYou need to pull the codes and see what they say. you'll need a troubleshooting flowchart to do the testing. There are times that the flowcharts will say to replace the ECU, but that is not always the right solution.Pulling the codes will not always be a solution, however. If the ECU is faulty, or if the ECU has a faulty power supply (e.g. ignition relay to ECU is bad), you may not be able to communicate with the ECU at all.Each vehicle's repair manual should have a flow chart of ECU diagnostics, outlining what connections/terminals to test for voltage and resistance. Essentially, if you have positively verified that all other electrical components are working properly, and you still have signal problems, then you can assume the ECU is bad.
here is an excellent forum with pics to show you how to flash the codes. it says ecu is found on drivers side, but my ecu was on passengers. it doesn't really matter... as long as you can find ecu you're set. make sure when you cut the wire not to plug it into the 3p connector. it's the 2 prong that you want. the article also has related subjects, such as "ecu reset procedure" (which you'll need to do once you fix the problem). it even has the official codes chart that you will read from. ---hope it helps
Because you should have bought a Fiat? "Another View". Alfa Romeo, along with many other vehicles inc Fiat have numerous sensors witch help the engine run at its best. Most probable list goes : 1 idle sensor. 2 maf sensor. 3. variator. Best option is to get ECU analized witch will point out exactly witch sensor is at fault or indeed some other problem.
The ecu is under the carpet on the passenger side front floor. Pull the carpet down & look through a hole in a metal cover. There will be a red led. Key off then on 1 blink means the ecu works, count the blinks after that for trouble codes. See the related link to find your codes.
If you are referring to fault codes stored by the ECU (computer), they are codes indication what part of the vehicle has a problem and what part is being effected by the problem. It can be an emissions problem, transmission problem, or other problem.
Not cheap nor easily...The engine is not the only thing which is required to be swapped out. Mounts, harness, ECU etc differ.
A good start would be to pull the engine codes from the ECU.
