Hi Everyone,

My question is how long (miles or driving cycles) should it take after reseting the MIL for the EVAP (EV) system to test? I ran my scan tool on the tour tonight, and everything showed as being "ready" except the EV System.

I just replaced an O2 sensor over the weekend and needed to reset the MIL. Since then I have driven about 350 miles or so and completed about 8 complete cool down/warm up drives. Nice to know that my 02 replacement got rid of the MIL, but wondering why the EV system is the only not showing as ready. Is there any way to force the PCM to test the EV system.

Thanks for any help or suggestions.

Roger
