Condition for fault memory entry
Lambda shift less than K_TE_OBD_LAM_DELTA and
ionic current integral shift less than
K_TE_OBD_AUSS_DELTA and
K_TE_OBD_AUSS_DELTA_NEG and idle reaction less
than K_TE_OBD_Leerlauf_DELTA at opening and idle
reaction less than K_TE_OBD_Leerlauf_ZU_DEL

Action in service
1. Conduct EVAP evaporative emissions control valve
system test
2. Check hose connections
3. Check evaporative emissions control valve, replace as
indicated
4. Following repairs repeat the EVAP evaporative emissions
control valve system test
