ok for the second time my CEL came on..once was months ago and i never pulled the code and ended up resetting the ecu so i never knew what it was..

now that this happened today i was happy so i can figure it out..also have had a rough idle for a while so hoping this is the reason..
anyway i jumped connectors like suppose to

the issue is this..

i get two blinks pause 8 blinks...is that code 2 and code 8 or is that code 28?

code 2 is air flow meter signal
code 8 is intake air temp sensor signal
code 28 is no.2 oxygen sensor

any help is always appreciated. Thanks

 

..so yea i might of already figured it out but i think the lexus codes i have are off..
one set says 28 is no2 oxygen sensor...another site says 28 is primary o2...
one site shows a 2 and 8 code another shows it starting at like 12
