Check Engine Light went Out 2007 NON FFV Malibu

Recommended Posts

A Few days ago I filled up on E85 in my NON FFV 2007 Malibu..  normally I have been running E50 in it over the winter but was on Empty and E85 was priced at $2.84 so I filled up..about 40 miles in and I get the usual CEL

 

 

Not a big deal as  I could see from the fuel trims from UltraGauge that I wasn't actually lean..

 

 

Anyway today after a total of about 130 miles the CEL went off ..  which just verifies that while the cars fuel map may have tripped a lean "variable in the database"..which then set off the cel.. that after so many miles and not actually running lean it shuts the cel back off.

 

 

so probably a short fuel trim out of range set in the database..but long fuel trims able to compensate and then turns the cel back off..

 

 

 

 

Which looks like the Malibu can run E70+ ..I still have well over a quarter tank left ..so I'll run that out and refill with E85 again (E70-E75 winter blend here in Minnesota)..and keep tabs on it.

Something to keep an eye on when spring blend starts tho. My '05 Rav4 would CEL with E81, but only if I wasn't driving like your grandma. Green at the stop light was a common place for that to happen.
