Do you speak OBDII? 'non-available' issue
My 2001 e350 V10 van w/ 40k responded with 'Not Available' from the OBDII during its inspection.
The NA areas were; Cat Conv Eff, Secondary Air, Heated O2 Sensor, Heated Cat, EGR flow, Evap Emis Cont Sys. However, the Engine Misfire, Fuel Sys Perf, and Comprehensive Comp were 'Ready'.
WHAT GIVES??? Since it failed at two inspection sites it's probably the van. Lastly, there's never been any warning lights on the dask and the local parts store checked codes and none showed. Anyone got any idea what / where to look? I need to get inspected ASAP.
