Guest AlexWeber Posted February 26, 2008 Share Posted February 26, 2008 My diagnostic screen on my '89 has been showing me "Engine control problems detected. Engine controls computer has detected an electrical problem. Service Check Required."and it kills on idle unless I continuously give it gas.I'm not too mechanically gifted and I would like to know what I'm getting myself into price-wise before I take it in. Any help? Link to comment Share on other sites More sharing options...
Machiner 55 Posted February 26, 2008 Share Posted February 26, 2008 You'll have to pull the codes and post them to get a good answer from the baord. Link to comment Share on other sites More sharing options...
D-a-n-i-e-l Posted February 26, 2008 Share Posted February 26, 2008 Sounds like acloged or defective idler air control valve. go into the diagnostic mode and check codes Link to comment Share on other sites More sharing options...
Guest alex_houston Posted February 26, 2008 Share Posted February 26, 2008 Codes will tell most.However, last time I had that my oxygen sensor was bad. Also, at the same time connector C102 had burned off one terminal and my coolant fans had quit working. I repaired these two and that message quit appearing.

DAVES89 Posted February 26, 2008 Share Posted February 26, 2008 Do you know how to get the codes out by pressing the off and warm buttons on the climate control screen? I see you are new to the forum. Link to comment Share on other sites More sharing options...

Then press and hold the 'off' and 'warm' keys at the same time. Have paper and pencil ready to write down the codes that will appear on the screen one at a time. The codes will be a letter and three digits. Example: B041Come back here and tell us what codes you have found. Link to comment Share on other sites More sharing options...
Guest AlexWeber Posted February 26, 2008 Share Posted February 26, 2008 Thanks for all the help and the welcome, I wasn't expecting to get this many replys so fast. I'll check the codes today and put them up (Assuming my diagnostic screen wants to cooperate). Link to comment Share on other sites More sharing options...
Guest AlexWeber Posted March 19, 2008 Share Posted March 19, 2008 I got the codes today. This is what I got:B552C553B482E171B482 is low pressure in the anti-lock breaks, I found that out, but I couldn't find/understand the other 2. Link to comment Share on other sites More sharing options...
Guest mongeonman Posted March 19, 2008 Share Posted March 19, 2008 b552 and c553 is caused by a lost of 12 volts,if you disconnected the batterie this is probably the cause,e171 is tha brake switch,the one one the pedal i think. Link to comment Share on other sites More sharing options...
Guest AlexWeber Posted March 19, 2008 Share Posted March 19, 2008 The battery did die recently and I had to charge it, would that give me those codes? Link to comment Share on other sites More sharing options...
Guest mongeonman Posted March 19, 2008 Share Posted March 19, 2008 the answer is yes for b552 and c553 and no for e171 and b482. Link to comment Share on other sites More sharing options...
Howard Posted March 20, 2008 Share Posted March 20, 2008 Welcome. Are the other codes, not B552 and C553, showing history, or current? Link to comment Share on other sites More sharing options...

DAVES89 Posted March 26, 2008 Share Posted March 26, 2008 This is the simplest reason for the warning to trip. Watch during the "light show" or simply turn the ignition key to the "run" position without starting the car and see if your "service engine soon" amber warning light that is located in the instrument cluster works. Mine was out and that was the reason my screen warned me. Nothing else was wrong.A very simple repair... Link to comment Share on other sites More sharing options...
ncgirl05 Posted March 26, 2008 Share Posted March 26, 2008 My SES light comes on while I am checking for codes, so my light is working. The electrical problem message came up again this morning on the way into work but it was only momentary and then it stopped. Link to comment Share on other sites More sharing options...

ncgirl05 Posted March 26, 2008 Share Posted March 26, 2008 I'm pressing 'warm' and 'off' on the climate screen and looking for codes - they are all History codes though. Link to comment Share on other sites More sharing options...
D-a-n-i-e-l Posted March 27, 2008 Share Posted March 27, 2008 This warning is often found when the E&C communication is interrupted. Tis is to say the ECU is not communicating with the BCM the radio brain, TCC control box, or even the insterment panel.I would start by checking for lose connections to each componnent, or in my case put back what ever I had pulled out of the system at that time.E&C= entertainment and climate Link to comment Share on other sites More sharing options...
Guest AlexWeber Posted April 2, 2008 Share Posted April 2, 2008 I went out and got codes again today. This time I actually kind of knew what I was doing thanks to you guys and I got a few codes.E034 CurrentE034 HistoryB482 HistoryB552 HistoryC553 HistoryI'm not too worried about the BCM's just curious.I don't know if this means anything but after I pushed yes when it showed "ECM?" And it asked all the questions surrounded by arrows labeled with 3 letters the one labeled "OXY" was blinking. Link to comment Share on other sites More sharing options...

DAVES89 Posted April 2, 2008 Share Posted April 2, 2008 E034 is the code for a mass air flow sensor. They are one of the most easiest parts to replace. It is the little black square electrical unit on the hose that goes from your air filter box to the motor. You may want to clean your intake as well with a product called Seafoam. Just do a search using seafoam and you will find more info that you need [in this case older then 3 weeks and less then 1 year. Otherwise you will get the discussion on Seafoam for transmissions]. This by the way is another very easy thing to do. Good luck! Link to comment Share on other sites More sharing options...

Guest AlexWeber Posted April 2, 2008 Share Posted April 2, 2008 Thanks a lot. I should of known it had something to do with the air filter considering the top of it is slightly ajar. It might be difficult since the bolts on my air filter are rusted and stripped but I'll get it taken care of. Thanks for all your help. I'm out to go wrestle with old Bloody Murder.

DAVES89 Posted April 2, 2008 Share Posted April 2, 2008 My air box was bad with rusted bolts and a broken mount to the engine compartment. You are in Minnesota. I'll bet Jim has one to send/sell you. Link to comment Share on other sites More sharing options...

D-a-n-i-e-l Posted April 2, 2008 Share Posted April 2, 2008 Did y clear the code before you started repairing/replacing parts? The code could be old or already fixed. I would write them down and then drive the car after clearing them. This will let you see if they set once again and are still valid. Link to comment Share on other sites More sharing options...

Guest steveskyhawk Posted April 2, 2008 Share Posted April 2, 2008 What is all this talk about cleaning the intake? Are you speaking of the intake manifold? That is the cleanest part of any car and should never need to be cleaned. Filtered air is the only thing that goes through there. This Seafoam stuff sounds like snakeoil. I've driven over a million miles and never needed Seafoam. Can somebody explain because I must be thinking of somthing totally different.My smog man told me that the oil from a K&N air filter can contaminate a MAF coil and make a cleaning necessary. Is this what you guys are using Seafoam for? Link to comment Share on other sites More sharing options...
