EGO Sensor

[Willis]

I ran a self-diagnostic on my 1992 325i M3.1 (see http://www.bonnevillemotorwerks.com/fault.html) and came up with error #1221. The code refers to an error with EGO sensor #1. I think this is the oxygen sensor b/c code #1264 refers to the EGO heater. The O2 sensors on the 3-series have a heater which heats the tip of the sensor for more efficient/accurate readings.

Does this concur with my assumption of an O2 (EGO?) sensor malfunction?

yeah its the oxygen sensor thast what it is. That means yours is bad and you have to have it replaced. I just had the same thing happen to me and the thread is someone on the borad. but for mine i have a 92 325is the sensor is $135 and you can fix it yourself or calgary bmw will charge you like $45 to replace it. Yeah so thats what it is.

Thanks for the help, I have already picked one up. Just for future reference they are still going for $135 a pop. Ouch!!
