ECM Complaining: p0133, O2 Sensor Circuit Slow Response
Hey. Mike, hey everyone.

My ECM started complaining about the response on O2 being slow. when I run Efie @ .37v or higher, But I think its still in closed loop because its responding to Efie and mpg haven't gone down.

is it possible to make EFIE voltage constantly varying but averaging @ .37 (like 02 sensors signal):question:

thanks

No, I'm sorry, the EFIE always adds a fixed voltage to the circuit.

Unless we turn it on and off 30x a sec. that would work....

Sigh

There is a circuit that will trigger it's changes only when the sensor goes high. You can find it here.
