Hello folks...

Got a dumb question... I just replaced my o2 sensor because the old one had 190k on it, guy i bought the car from was a total moron. Anyway.... with the old o2 sensor (at the manifold) I had my a/f guage connected to the white wire and it worked like a champ. Well, now with the new o2 sensor, I get nothing off the white wire. There are no codes getting thrown out, or anything weird happening, other than the guage i have don't work suddenly. I hook a multi-meter up to the white wire, and i get nothing...... possible bad o2 sensor?

The white wire is the signal wire right?

It's a 4 wire, White, Blue, and 2 black.


Any info would be greatly appreciated!
