How do you get to the engine computer - 2006 Hyundai Sonata

As far as I know, the engines are basically identical on the outside. The problem with engine swapping on these computer-controlled cars is, you also have to change the computer since each engine has a computer programmed for that particular engine. This often requires not only changing the computer but also changing wiring harnesses to match. In short, the engines will most likely swap but it is the computer that makes the difference.

A few Japanese car makers, maybe others too, use different terminology for the same system that today manages all vehicles, the computer controlled engine management system. The ECU -Electronic Control Unit- is the computer of the system, has a lot of sensors, and output switches and controls to run the engine under all operating conditions. Just like other makes, American cars for instance, call the computer the ECM - Electronic Control Module, or sometimes PCM- Powertrain Control Module. Different terminology, but all mean the engine computer. Now that computers are proliferating in vehicles- computers to run many different systems-the engine computer is considered the primary computer on the car. The ECU in your case.

if you had someone put in the engine they should have reset the computers-its not transmission in limp mode its your engine and the computers have to be flashed to the engine most shops dont have the software to flash or reprogram the computers as to the transmission same if you put the engine you can ask a dealer what options you have, to get the computers reprogrammed

I would think so. If you go so far as to change the engine the computer would need to be re-set to match that engine. Remember, when you get the car initially the engine is programed to the car's computer settings. But I'm sure that if you take it somewhere professional (anywere like Nissan, or Sears Automotive, or any auto car repair/maintenance) they will know to do that when they change the engine.

asuming both engines were the same capacity 1.6?1.4? and all parts from first engine were used like air intake/airflow meter etc then original ecu can be used,if all the cavelier parts were used then ecu from donor could be kept with wiring loom etc.poor running could the ecu be running "get u home"mode needs reseting then codes read.if wiring loom from corsa kept are all the sensor wires connected to correct parts of engine?oil temp/water temp/flywheel sensor/oxygen sensor/etc even speedometer all needed for ecu to adj correct fuel air mix for smooth running.was the donor engine running ok b4 its transfer?if u havent already go join an online corsa.org type website where multiple vauxhall experts will be found to help

imobbliser and engine control unit have to be matched or programmed ,,, if its the same engine put back old engine computer and all should be ok

Engine Control Computer is located in the front seating area, passenger side, under dash, mounted behind kick panel

Hello there
let me try to explain it the best way i can

If you are talking about the light coming on when you are driving in slippery conditions, this is normal. If you are talking about it staying on all the time, the ets is either turned off or you have another problem. Let?s take a moment and explain why the electronic traction control which is called Enhanced Traction System (ETS) warning light will turn on when the engine computer sees a problem. The ETS system monitors wheel speed via the Anti-lock Brake System (ABS). If the ETS system sees a wheel spinning due to snow, ice, rain etc., the ETS computer sends a request to the vehicle?s engine computer to reduce torque. The engine computer responds with a combination of strategies. In the engine computer?s bag of tricks to stop wheel spin it can perform any one or combination of the following; cut fuel off by trimming or turning off fuel injectors, ****** the spark timing or up shift the transmission. In the days of old we just let up on the gas pedal. Now the computer does it for you. If you have an engine running problem it is more of a problem than you realize. The engine computer is the high command center. The engine computer will work and respond to information from the other computers in the vehicle. But in the event there is a system or running problem that the engine computer is responsible for, ?it will? lock out all of the other vehicle computers. If there is an engine running problem that causes the engine computer to store a code and turn on the ?Check Engine? light guess what computer doesn't talk to the others? The engine computer. The ETS computer gets all put out when this occurs and turns its warning light on in protest. So, there you have it. If the check engine light is on the ETS warning light will come on as well and the ETS system will not operate until the engine computer problem is corrected.

Start by checking your ground wires there is more than a few on a 2001 ......if the wire is burning something is grounding a +
