LTFT Showing Zero's

[Mr.VU]

Holden GenIII 5.7ltr, New Engine, LTFT showing zero in VCM Scanner. Cleaned O2 Sensors, Checked plugs. Scanner showing 450Mv for O2. LTFT Enabled in Editor. At a loss.

450mv is a default no signal. You probably have wiring issues.

[Mr.VU]

Thanks. I'll investigate all the wiring and connectors.

Check for power and ground at the oxygen sensor connector.
Then you can use a short peice of wire to jump out the pins to test the Min and Max readings with scanner connected.
