check engine light Options

[6strngs]

so, the check engine light on my car lit up. The car still ran fine and everything, I stopped and restarted a couple times today with no problems with anything, everything seemed normal. I think I know what caused it. about a week or two ago, I decided to unplug the hose connecting the EGR to it's source of vacuum. I read about it on mr2oc.com in one of the threads about NA 5sfe power. anyway, after driving around like that for a while, I decided that there was no noticable difference and it just made a wierd sound before 3-4K rpms and might've also been giving me a slightly high idle. so I decided to plug it back in today. but after I did, I noticed that after a while that the yellow light that had lit up on my dash wasn't the fuel light like I thought, but the check engine light. I wanted to get a paper clip and see if I could get a code for it, but I was with my girlfriend today, so I was... occupied. So I was gonna check it right after I got home from dropping her off, but the light went off on my way home. so, the question is, could it have been from reconnecting the EGR? and why would it throw the light to reconnect it? if anything, wouldn't it have thrown the light by disconnecting it?

Try to reset the ECU ans see if the code still show up.
You don't need to disconnect the battery to reset the ECU.
Just remove the EFI fuse (15A blade fuse in the main fuse box) for 10-15 seconds and put it back.
Disconnecting the battery will make you lose clock and radio setting.

And if you want to disable code 71 permanently, just short the pins on the EGR temp sensor.
