improper resistance ohm testing my afm.

DRIFTINGmy85 · 11-30-2006, 07:23 AM

My afm doesn't show proper resistance when ohm testing e2-vs. It is supposed to be 20-1000 from fully closed to fully open with the resistance change is accordance to the position of the measuring plate opening.

With it at fully closed ohm = 29.
Fully open ohm = 25.
Moving the plate back and forth from open to closed results in 44 highest and 15 lowest. Only going super fast does it reach up to 4.23 or 2.45, But seldom.

Could this be a reason I'm idling very high?

Note: I do need to adjust my tps.

sometime broken caps and untight rotor does effect your idle too... need to check that...
