I replaced my ecu about 3 weeks ago for my Honda. Intermittent signal to injector. As a previous post noted, you can purchase a rebuilt/tested ECU or ECM from Cardone. [major ECM rebuilder] They are business to business only but you can order it from any auto parts store. My cost $200 plus $40 core. It's an easy job. ECU is usually in the engine compartment, at the passenger feet or under a seat. Takes 5 minutes. A few plugs and a few bolts/nuts. Mine didn't need programming.

I would only trust a company that does REAL repair/remanufacturing of ECM's/PCM's and other component level auto electronic work.

There is a lot involved in doing a proper rebuild of a car's computer.....mainly, properly diagnosing what is wrong with the PCM they are going to rebuild. I would look for a rebuilder who has a long and reliable track record in this area.

Buy a working one from a salvage yard with a warranty and then have it reprogrammed for your vehicle.

I have a 1996 Hornet motor home with a f350 chassi and a 7.5 V8 that's in the shop. Been there for 6weeks now. They keep finding things wrong. All started with a tune up. Then they suggested I need to decarbonize the engine, since it was sitting for a couple years. The injectors kept clogging so they did it again. Then they said it was the ECM, which needed to be replaced for $900.00. They just sent me an email now saying it's being rebuilt. I think I'm being taken to the cleaners. Any suggestions on how to confront them when they give me the bill.

The ECM will cost me around $1,300 to get it replaced (at the dealership). Here is my question..there is a garage in a nearby town that says they can rebuild the ECM for around $500. Can this be done? I have had other people tell me that you cannot fix an ECM, that it needs to be replaced. I called Auto Zone to see if I can buy the ECM there instead of at the dealership...I can..but they can't find the price for it. Any ideas?? Thanks!!

Get a 2nd opinion. Unfortunately many people and technicians will assume its the most complicated part that causes a problem, when in fact, most of the time its a simple common problem, like in your case, maybe the compressor is not running due to low Freon, and the pressure switch cut it off. or a faulty pressure switch, or relay. It could be anything.

If it is the ECM, you may have to take the part numbers off the old one, and the scrap yards can check and most times match the part number. All ECMs are not unique, or made specifically for that vehicle. They are made for a vehicle that has all the same equipment, engine size, etc., etc., and will interchange with any vehicle that's just like yours, which may have been made in the thousands. In your case, any 2005 KIA Sportage that has all the same equipment that your has, will have the same ECM.

Its possible if the vehicle has an AC cutoff for Wide open throttle, which the signal would originate from the TPS and be sent to the ECM, I would think. However, have never heard of one quitting due to that.

Instead of "Shotgun" replacing parts, hoping to hit the problem, have it checked out and ask for an estimate. Doesn't sound like an ECM problem.
