Closed Loop

[GTS Dean]

Closed-loop is fully warmed up and running in a range from above idle to between 3 and 4000 rpm. WOT is usually open-loop.

The blinky codes are only available on cars thru about '98, I think. They just tell you what fault code has been set in memory.

"The blinky codes are only available on cars thru about '98."

The blinking codes work on cars '97 and older.
