Cut the wire. Out of curiosity, what have you just done to fix the motor! Changed the wobbulation relay!

Or if you can't get at the wire, put a smal square of black tape over it.

Um yeah well um!
The um &**check engine** light actually doesn't come on when ya need to change the whole engine.
it just means ya connect a coupla wires together and read the code it flashes at ya and then replace the faulty sender unit that brought the light on- weird aye

droping the engine out, cleaning it and changing gaskets.

And was this light on before you took the engine out, or did it only come on afterwards!Check engine lights only come on when the engine management computer has detected a fault in one of the circuits of the various bits and pieces it controls and receives information from.It doesn't care if the engine has been leaking!If it only happened afterwards you've probably left something unplugged.

most likely a sensor left unplugged - if it came on afterwards

Its only came on afterwards, it goes off but comes back on.

You need to double check that everything you touched is plugged in properly, getting whatever fault codes it has spat up read out of it will help ID whats causing the problem.Sometimes after the affected circuit has been repaired the code needs to be manually deleted before the light goes off permanently, or should I say after the engine starts it should go off.

Find the little grey box with diagnosis written on it .open it and bridge the terminals marked Te1 to E1 and turn on the ignition. this will bring up any codes stored in the ecu. The light will flash a set number of times . ie 3 flashes then 1 flash thats code 31 then a gap and it either brings up another code or the same one. look up the codes on the internet or phone up your local toyota dealer and ask.
