here we go...
i have a 1992 honda accord DX
we had a problem with the TCU, it had a burnt resistor. the person we took it too said they could fix it with a new resistor.
cool okay thanks.
got the car back and it worked flawlessly, until the floorboard under my girlfriends feet started smoking and the car came to a very abrupt halt.
i hurried up and took out the tcu and threw it in a puddle to make it stop smoldering....
once we got back home (driving in limp mode once again because there was no TCU) i go to take it apart and the sumbitch had superglued the whole case closed. about 2 hours later and much prying and slamming, we finally got the thing apart, there was no new resistor, just a damn wire! he took the wire and loosely wrapped it around the burnt resistor. i mean, hey it worked, until it tried to turn us into bbq! found out the wire came completely loose and touched another resistor and shorted the whole thing out.
so i bought a new TCU on ebay, totally remanufactured, from a 5* seller. put it in the car and nothing changed, so i took the resistors that he put on it and resoldered them. still no avail. there was a piece on it that looked like it needed to be touching something so i put a little bit of solder on it and took it back out to the car, the d4 light stayed off until i turned the car on, then it flickered and then i heard clicking from the gearshift and what sounded like the tach, and the light flickered with the clicking...

so my question is does anyone know what this could be? ive checked solenoids, some of the wiring, the TCU, almost everything i could think of... im really on the verge of torching this car but i spose i need a way back and forth... if anyone could help me please help.

 

i should add that after the flickering the light stayed on,

 

and doesnt throw any codes, but when i jump the wire the CEL stays on

 

that blinking d4 could be your vss sometimes google/youtube have the answer your looking for and will show you how to fix it other than that id beat the living **** outta guy who supposedly fixed it and get my money back, bad resisters are not to be bypassed they were put there for a reason. if they go bad replace them with equal value resister not bypass them

 

Trust me i want to so bad. I called him and told him hes a worthess **** and he hasnt answered to my number since

 

And thanks for the quick reply btw. Ill check the vss tomorrow.

 

Also I don't know if it matters but another thing that happens is if the tech gets to about 3 1/2 then it starts flipping out..

 

It's not often the tcu goes bad. Just pull another from the junkyard.

 

phone call? my how generations have changed lol...anyways...
that would just be starting point research online google and youtube other people around the world has had the same car issues and turned to the internet. and goodluck

 

Believe me I have googled until i have turned into google. And yes I called because he was 2 hours away lol anyways, I'll check the vss later on and probably the throttle position sensor, and to replaced all bad capacitors and restistors in the tcu but if nothing else works then I'll take the plunge in getting yet another tcu. Wish me luck
