I dont have my cats since yesterday, and i just popped a SES light... thing is, ion removed the code for me from the PCM...

I'll have it checked on saturday, but what else can no cats trigger the SES light for?

maybe something irrevelant?

 

If you have an O2 sensor located after the cat, you will need to install an "O2 simulator" in it's place.

 

Could also be P0400 (insufficient EGR flow) due to the lack of backpressure from removing your cats.

 

not if u remove the code from the computer...

damn i wish i had the thing to check it! errrr
