I did the paperclip test and I got two codes:

(1) Oxygen Sensor

and

(20) !!! what the hell is 20?

I looked it up in the Helms, Chilton's, and Haynes and there's nothing for CEL 20 for my car. I made sure to watch carefully the sequence of flashes. Two long flashes back-to-back, a long pause, a quick flash, long pause and repeat. I know that during my install I accidentally yanked on the oxygen sensor wire, not to mention it's old, so I know it needs replacement. Any thoughts guys?

 

the chart i have says that CEL code #20 is Electrical Load Detector.

i've never had that code before so i'm not sure i can help out much more than that.

oh yeah and code #1 is the infamous O2 Sensor, the one i always seem to get.
