And i am also looking too find ECU error codes for this engine i have had a good browse on the net for these codes but have'nt been able too find them for the QG18DE engines all i seem too find is the SR20 engines .... Please Please Help me .....

Thanx in advance for any help recieved

there is no manual diagnostic. it's much, much easier to purchase an OBD II code reader.

thanks Mike a friend of mine was gonna check it for me but his code reader is a obd 1 ,
He told me too run the engine for approx 50 miles and the management light should go out,The problem was i started the engine with the temp sensor unplugged (My mistake Dohhhhh) and he said the ecu has picked up on the fault .So i will run it and see if it will go out keeping my fingers crossed ...

either that or unplug the battery for 10 minutes.

Cheers Mike i tried dis-connecting the battery for a couple of hours but that did'nt work .
I have managed too re-set the engine management light now by crossing 2 wires on the consult plug under the fuse box took me 2 seconds too re-set the light by crossing the 2 connectors on the bottom row of the consult plug far left and far right on the bottom row ...
Used a strip of fuse wire plugged it into both plugs turned the ignition onto the on position and the light began too flash ,Then switched ignition off , Removed the wire and started the engine again and the light re-set woooohoooo
But i do appreciate all the advice and help that you guys can give me on here

if the light doesn't go off, that generally means there's still a problem.

yeah my friend was telling me that too but the light went out no problem once i had switched the ignition on and off after crossing the wires on the consult plug ....
