[QUOTE="WZL 96, post: 14848374, member: 139673"] Hey guys I found time to do a smoke test today, and the results were inconclusive. Not the slightest puff of smoke from where it shouldn't be. I [I]did [/I]however plug in my scanner and looked at the o2 sensor voltages. As you can see in the two photos below, o2s11 (bank 1 sensor 1) reads between 0 and .01 volts. The other sensors read to normal levels, leaving me to believe I have a fault somewhere with the sensor or wiring. Post cat bank 1 sensor 2 (o2s12) reads at a normal level which makes me certain that it is not a vacuum leak. the sensor harness looks okay and the sensor is new so I really do not know where to go from here. I'm going to swap the precat sensors to see if that does anything but I am really at wits end on where to go from here. Do these cars use any electrical modules or devices in the harness that deals with the o2 sensors? [ATTACH]42141.vB[/ATTACH] [ATTACH]42142.vB[/ATTACH] [/QUOTE]
