Alfa 147 Throttle Not Responding Issueadmin
I have read online many times of people having problems with their throttle that stops responding and giving a motor control failure coupled with selespeed error. I myself have never come across this problem until Now. My wifes Alfa 147 Selespeed started giving motor control failure that resulted in a throttle that was unresponsive but after switching off the vehicle and restarting the car it was fine. It started getting worse up to the point where we could not get the vehicle out of the garage. I then started fault finding. I wanted to eliminate all the big possible problems first so i replaced the ECU, Throttle Body, Body Computer, Throttle sensor and selespeed ECU. But still the Throttle Not Responding problem was there. I then removed the plugs located on and around the throttle body as well as the plug that plugs into the throttle and soldered the wires straight together but still the error was present. After many days of frustration I found this plug between the engine and firewall just above the brake booster. I opened it up cleaned it out with electro clean spray and reassembled. The job took me about 20 Minutes. The car has been driving now for 4 months without any issues. So I recommend starting with this plug first.
