Emissions Question "Not Ready"
2002 f body running COS#5 need only to pass ODBII system readiness test. Any help, please pm if you dont want to post on the forum.
Any DTC's...?
Do any Mode $5 or $6 tests fail...?
Went through this with the 05 Truck and COS3 . EVAP ?
All else can be "not reported" .
Use Scan Tool and check SRT (System Readiness Test) through it before going back .

NO DTC's but not getting green check on O2's. Also getting evap not ready. Can only have one not ready to pass.

O2 will become ready with just a few engine on/off cycles that is if nothing is wrong with them (not reported) , EVAP , that one is a head scratcher (can take forever to go to "ready" state) .Originally Posted by minytrker

O2's still not ready after several hours driving and on/off cycles. The car is running on the o2 sensors.
Can't pass emissions
I have a 06 C6 LS2 that won't pass emissions. The evap, O2, and heated O2 monitors will not come ready. Does anyone know what DTCs to change to get them to come ready?
Where are you located...?
