getting these codes after headers a few times. what does it mean? Can I delete them? is this a problem or are the sensors just cold.

 

sensors are just cold...they arent heating up fast enough...if you have edit or can get custom tuning have the codes turned off

if you get other 02 codes like switching, etc...then there is probably an actual problem with your 02's

i think everyone that has longtubes sees these heater codes at some time...

 

so i guess im gonna get them deleted out of there then i keep throwing that code and the o2s are good...i just put new ones in lol, well new old ones and they work great...

 

If you don't get SIMMS, O2's Edited out, or new O2's, let us know and I will detail the diagnosis on this code. Do remember that those HO2S are FRAGILE, sensitive to contamination and there is an important TINY air passage in the "pigtail" lead that can be damaged with rough handling or improper installation!

 

i deleted the rear o2s out with predator and the front o2s are just not gettin hot fast enough for the start up test or whatever it does. i deleted them and they didnt come back, this is the second time they came on and it was when it was about 30 deg outside too i might just deal with it and reset it every time it come
