The code is for a Bank 1 O2 sensor slow response. My problem is that I'm not getting any voltage readings for either the Bank 1 or Bank 2 front O2 sensors, just 00.0 volts on the data list. Anybody know if there is a common problem with the wiring? I know MAF sensors can cause false lean codes to set for the O2 sensors, but I've never had no voltage readings on both front sensors before. WTF is going on?
