Howard Posted October 1, 2000 Share Posted October 1, 2000 I doubt your CD installation caused any of your problems.<BR>OK, lets see what we have got here:<BR>E034 Current-(current means to problem is happening now, history means it has happened in the past but not a problem right at he moment). I think this is what is causing your problem. It is the Mass Air Flow Sensor circuit. Most likely the sensor has gone bad. The other codes would not effect the running of your car.<BR>B122 Current is the Panel Dimming Potentiometer Circurt (bad headlight switch)?<BR>B123 Current Panel Lamp Switch Circuit. Related to above (bad switch)<BR>B552 History BCM Keep Alive Memory Error. This error has always comes up if the battery has been replaced or power has been interupted to the BCM.<P>What I think you have is a bad Mass Airflow Sensor. The ECM uses signals from this sensor to make fuel delivery calculations.<P>Hope that help you out some. <BR>Howard<p>[This message has been edited by Howard (edited 10-01-2000).] Link to comment Share on other sites More sharing options...
Guest Posted October 2, 2000 Share Posted October 2, 2000 I just got a RF modulated CD changer installed in my '89. Three days later, out of the blue, the car stalls while idling, and then when I hit "Drive", stalls again and dies. I get a "Electrical error detected, service check required" message flashing on the screen as soon as it starts stalling.<P>I managed to get home eventually, without her dying or stalling on me again, but I'm afraid she's gonna leave me in the road somewhere if I try again. Can anybody give me any advice? This is my only mode of transport, and I need to get her back to normal without spending a fortune!<P>I did the ECM code check thing, and I get the following:<BR>EO34 - current<BR>EO34 - history<BR>B122 - current (ABS, I know)<BR>B123 - current (brakes too?)<BR>B552 - history<P>Help me, please!

Guest Posted October 2, 2000 Share Posted October 2, 2000 Thanks for your prompt reply. I went to my local Buick dealer today, and got weak at the knees when I got quoted $480 for a new mass airflow sensor. Figured I'd have them check the problem to make sure before spending that much. Koons Buick in Alexandria, VA happens to have a mechanic who specialises in Reatta's - he drives one himself, so he is checking the car for me, and if the airflow sensor is the problem, I guess I'll have to fork out the money. Also taking the opportunity to replace my ABS accumulator, since the light has been coming on a lot lately. I am lucky that they have both parts in stock, and also for the Reatta specialist, but I may be more than $1,000 poorer when all this is over.

Guest rong Posted October 2, 2000 Share Posted October 2, 2000 Would you post the GM Part # of the mass airflow sensor when you can get it?<BR>Thanx, Link to comment Share on other sites More sharing options...
Howard Posted October 3, 2000 Author Share Posted October 3, 2000 Frankly, I hope I'm wrong, but that is the code that was set. Let us know if that was indeed the problem. <P>Howard Link to comment Share on other sites More sharing options...
Guest Posted October 3, 2000 Share Posted October 3, 2000 The problem was, in fact, the mass airflow sensor. See "Mass Airflow Sensor Price Shocker" post for details.<P>Thank you for your advice. Link to comment Share on other sites More sharing options...
