CEL translating for dummies

[PapaPump]

Hey Gang...

I had a CEL pop up on me the other day, so I decided to be manly and go see what the heck was going on, so I whipped out a paper clip and to my amazement my check enging light start blinking just like you FZJ80 Fanatics said it would..

Heres the deal..

My Light did this..

Blink

Pause
Pause
Pause

Blink
Pause
Blink

Then it blinked 7 more times.

So either it is telling me I have a code 12 and a 7 or a 27.. or maybe it is telling me to put more gas in it.. who knows.

Can anybody with more experience with these codes translate for me?

BTW.. the Croozer runs awesome.

Thanks!!

That looks like 27. Did you put the clip in, then turn the ignition on? The single blink followed by a long pause is just a "bulb check" AFAIK.

27 = Sub Oxygen Sensor Signal.

Whether there's only one or multiple codes, CEL will keep repeating from the lowest numbered code to the highest number code. Short pauses between digits of a single code, long pauses between codes.

Go try it again and take your time till you're sure of what you're seeing.

Ok... I have myself a code 27... I turned off the CEL, and I drove about 50 miles today without it turning back on.

Last week I ran some sea foam through the intake.. I must have gotten some crud on the front 02.

If this happens again, It looks like I will be installing a pair of OEM o2's past the cat guard on a MetalTech slider..

Thanks for all of your help!!!!
