Anyone want to take a stab at this?

Hey all,

I am trying to get the O2 sensors working on a 4.8L in a 61vette. I installed te O2 sensors with the wiring as follows:

Bank#1
A - C1-29
B - C1-69
C - Ground
D - Switched 12v

Bank #2
A - C1-26
B - C1-66
C - Ground
D - Power

Now, this car is running a tremec 5 speed. I do not have a vehicle speed input to the ECM. Does this matter? All it does is reads 0.448V +- .005V with the sensor plugged in or not. They are brand new Bosch sensors, PN: 15284

Can anyone maybe shed some light on this for me?

I have attached my cal

A=NBO2 signal ground
B=NBO2 signal
C=Heater ground
D=Heater power

Is that how you're wired up...?

That is correct.

Try setting B4206 to Disable.
