I can't believe I don't know how to do this, after all the years I've studied.

How can I check a CEL on OBDI board, when everytime I click the key back one click, the code goes away??? I can't check the code while the car is on, can I ?

Restart the car, Code gone......Right so, during decel, in gear, foot off the gas, the injectors seem to "turn on" and BAM! CEL comes back on. (only happens on decel, in gear, foot off the gas completely)


frustrated

 

check it while the car is on. Wont hurt anything.

 

****, I forgot to list the setup.

(99 si) B16 stock for the most part.
Uber
440cc inj.
3" turbo back
PLX
Street tuned.

Won't hurt to check it while the car's running?
I was afraid of burning something up.

 

nope it will be fine

 

naw it wont hurt anything..

 

With the car warmed, and throwing a CEL after a >6-7sec decel, Id put my money on it showing o2 code once you check it.

yea very true...uberdata likes to be gay with throwing that code if you dont have the sensor hooked up and in the exhaust flow.

 

The primary is still hooked up. I'm not using the simulation signal from the PLX. (two bungs in the DP)

The secondary O2 sensor has been removed.

I figured it was probably O2..... Thanks for your help.
