Default How do I clear Cels?

HI,
I had a cel in my car (95 dx, chipped po6, Ls/vtec) for my IACV, I realized that the plugs were switched between the evap purge sensor and the IACV. After I fixed it the Cel was still there. So how to I reset the cel?

You can do either of the following:
1. Pull the backup fuse for the computer for a few seconds.
2. Disconnect the negative battery cable for a few seconds.
3. Use a scan tool.

The easy way is

Turn off car, pull up the 7.5 amp backup fuse in the fuse box, tap the brake, put it back, start the car and let it idle for like 5 min. without operation anything(no power drain or throttle input), shut it off, done.

u can usually get away without the last idleing part unless it idels like crap after u start it up

the CEL should go away once you turn the car off and on from my past experience. if you did hook it up right that is.

That's usually the easiest way to do it. Even the fuse pull method really never worked for me, and since my battery is relocated to the back of my car and buried under a speaker box, i usually just yank the ecu...easier for me to get to

Well, now when I jump the 2 Wires I get a Solid Cel Instead of the blinking readable type. Why would this occur??
My setup:
95 Dx
Ls/Vtec, no turbo
Chipped p06 by Xenocron, running a P30 map with Knock sensor disabled.
DSM 450's with resistor box wired

The car seems to Idle really good, I adjusted the timing, replaced/adjusted the TPS, and dialed in the Idle screw. I haven't actually driven it yet so I don't know whether or not it is in limp mode. Is there any reason other than bad chip/ecu that I would be getting a Solid Cel??
