#1999 of 2107 1990 Honda Accord Issues
Jan 03, 2011 (6:52 pm)
I am looking for help on a few issues I am having with my 1990 Honda Accord.
Recently I noticed that my Honda wouldn't let me take the key out of the ignition and thought it was the break switch which had broke off...this has sense been repaired. So now I still have some issues with it getting stuck..but if I wiggle it some it will eventually click into Park and let me take key out.
Also the car seems to be shifting hard and the check engine light comes on at about 50 to 60 mph...it will then go out once the car is shut off and doesn't come back on until around 60 mph again....today the S light came on at the same time and was flashing. I replaced the TCU about 5 years ago....but when it went bad I couldn't get it to go into gear at all....the RPM's would rev up and I would be going down the road and it would change to a low gear...I haven't had those issues so far. When I shut the car off the S light didn't come back on again with the engine light?
I attempted to find the blue connector thing under the passenger side so that I could find out what the check engine code was but was not successful in find it.
While looking for that I noticed there is a wet floorboard on the passenger side found another issue....the windows have been fogging up more on the inside lately but the heat is still working. Would a leaking heater core be the issue and would that cause me issues with the TCU possibly?
Trying to figure out how much more money I should put in this old car….I have already did a good bit of front end work and it still needs tires balanced and struts…
Thanks for any info you can give on these issues!

I sent you an e-mail with a photo of the data link connection so that you can find it.

Thanks...I finally found it! The service code I am getting is 43...would that cause issues with the computers? I believe it is fuel system issues? If not what do I need to do to correct that? So you think the computers need to be replaced...because I am having some shifting issues? Would the S light come on due to code 43 you think? Thanks!

I wasn't the one who suggested replacing the ECU, although this could be a possibility. You might try going to the underhood fuse/relay box, and disconnect the BACK UP fuse for 10 seconds, to reset the ECU.
I'm going to e-mail you a diagnostic flow chart for Code 43, to show you all the things you have to check. It might be a bit hard to read, so you'll have to blow it up on your computer screen.

Thanks...yes I am having trouble reading it..but need to print it off too look at it better. The S light hasnt' come on anymore...just the check engine light every time I get to around 60ish MPH......then it almost feels like the car is going in and out of gear or something..the RPM's go up to around 3 and stick there.....just seems like the power is forced or something....and then it will almost go up and down the engine sound....just feels weird...but not sure what it could be. I also have a whole in my muffler do you think that would cause the 43 code? Thanks for your help!

My experience has been that the computers for the engine and transmission start to fail at about the same time. Usually around 100k and the reason why is mostly parts on the circuit boards have a lifetime that is around the same as 100k miles on the odometer... Give or take... Id consider the ecm and tcm at around 100k. If you need to get a mechanic to test the computers with a scanner and see what it says...
