Ok guys check this out.I ran out of petrol(ok I am a girl!) and the yellow engine light stayed on afterwards.Hyundai said I would have to sell my soul to get it sorted but would be ok to run I t failed it's Mot on emission,but the local garage managed to temporarily fix the problem to get it through.The light came back on after wards-!!! So I did some research on Internet and here's how to reset it yourself-- Take off positive lead from battery,then turn ignition key on to get rid of any stored power.Then pump the footbrake(yeah I wondered why!) for about 20 secs.You will hear allsorts of clicking in the engine as ecu resets.Then reconnect battery lead!! Wallah !!!!
I went armed with this knowledge to the local garage(much to their amusement) and asked if they could reset the ecu,and they said a dealer would have to do it.I said well I know how and asked them to disconnect battery for me(their frowns got deeper by the minute).The rest I did in front of them,They were gobsmacked!!!!
They were amazed and asked me to call in a few days to tell them if it had worked permanent as they had learned something----so far so good!!!!
I f you have a computorised radio make sure you know the reset code for that as it may knock it off.
The ecu resets when you drive away.Now drives like a dream.

My light came on on my accent, I took a look at my air filter and found that a mouse was using it to store food, I cleaned it but the light stayed on, so I disconected the battery for an hour or so when I put it back on, guess what, light off back to normal

1999 hyundai coupe 2litre automatic. does not appear to change into 4th gear and engine reving high


you may have lost 4th gear and need a major repair or new trans. but it could be just a faulty sensor (hopefully because it would be much cheaper)....... a mechanic should be able to tell you with a quick inspection......good luck

Blown ecu fuse


ECU= Electronic Control unit. This is what controls all the engine electronics. All the sensors on the engine and other things are routed through the part. What it does is tells the engine how to run. Each sensor plays a specific role. The ECU reads how much are the engine is getting, tells the engine how much gas it needs, etc. Try digging around a salvage and finding a new ECU. Swap it out, and if it is still blowing the ECU fuse then you need to start looking for shorts.

My Hyundai xg300 downshifts from 5th gear into 3rd gear. We have changed the mass air flow sensor and some other sensor that is attached to the transmission. We never wash the engine so it's not water on...


Yeah... why did you change the MAF?... Someone tell you the MAF caused your transmission to shift from 5th to 3rd?... I don't think so!
Did the 'Check Engine' Light come ON? Whenever the 'CHECK ENGINE' light comes on, the ECU (Engine Control Unit) sets a Diagnostic Trouble Code (DTC). These codes identify the particular engine management system which caused the light to come on. You'll need to use/find an OBDII (On-Board Diagnostic) Scanner to retrieve any code which have been stored in the ECU computer. Afterward, we might be able to help you DIAGNOSE and perhaps eventually fix the problem.

Obd diagnostic


Look under the hood in the engine compartment.The emissions sticker will tell you if it is obd compliant...If it is manufactured in the u.s. since 1996 , federal laws require it to be obd compliant..I would give the manufacturer of the scanner a call to check compatability...Good Luck!!!
