VAFM no resistance on vc-e2 (confused on pins)
Been having problem with poor fuel economy, hesitation, and bogging down at cold start. Tested the tps today it looked good went to the vafm and everything seemed good until i got to the vc-e2 measurement. is this serviceable or replace? it looks like a fixed resistor on the diagram.
OK now i'm confused which pin are which

According to these folks: http://personal.utulsa.edu/~nathan-b...sm/engine.html there is a different pin-out for the 22re and the 3VZE. Since you've declined to reveal your affiliation, I can't go any farther.
The VAF is not a "serviceable" component, but for the cost of a replacement there's no reason not to try.

Its a 3.0 and i traced the wires back and figured that thanks. The vc-e2 is fine but the vs-e2 at idle is out of spec. Is this part adjustable with the gear inside the vaf if you pop to top off.

VS-E2 is the "wiper"; it should vary smoothly as you open the flap. The "spec" is the entire range; if it is outside of that spec you probably have a short or open. Adjusting the gear would not affect the range (but it will probably make your truck run badly).

The ohm reading will jump on the wiper circuit.

When i tested voltage it went smooth from 4.8 down to.38 v
