Topic: Check Engine Light

[Hooch]

Took my 4Runner (22RE) to Winter Fun Fest. As soon as I pulled it off the trailer the check engine light came on.   It sounded fine, idle was fine, but had no power. Drove it all over town days before I left and it was fine. Was it because of Friday the 13th? Probably not. I was hoping it was something to do with the high altitude and would adjust its self.   It never did and now i'm back home and its still on.  It will run and drive but no power at all.
 I just got back Yesterday so I havent had a chance to rip into it yet. Any suggestions were I might start?

Check your error codes.  The only time I had that light come on and stay on, my alternator had went out and was overcharging the battery.

Was it running but with no power? Or was the engine light just on?

Only one thing. I've worked on all of my rig but the engine. I mean I've changed the oil, filters, plugs, wires and that chit. But not much more then that. How would I check my error codes? Do I need a special tool?

I assume you have a 22re. To check the codes, grab a paper clip and unfold it into a "U" shape, then open your hood and on the passenger side of the engine compartment there is a smal blackl box, which I believe that says diagnostic on the top. open it up and on the inside of the lid will be a diagram of what each port is. locate and identify the T1 and E1, (sometimes it only says T and E1) if you are standing in front of the hood it should be the middle one and and the far back/right one. Anyway put one end of your paper clip in the T1 and the other end in the E1, then turn your ignition to the "on" position and watch your engine light, it will flash several times depending on what the problem is. There is a good linke on this board I will look for which will tell you what each code means, untill then good luck

in most cases, but if it is an 85 it will be alittle yellow plug on the drivers side inside the engine bay behind the intake on the side of the truck it is plugged into alittle rubber grommit. pull it out and put the paper ciip in it,
