Hey all, ever since I got this Z 1 year ago, I’ve been struggling to figure out 4 02 sensor codes.
P0139
P0137
P0159
P0158
The codes are permanent, so I’m screwed on getting this thing registered until they are fixed. The emissions monitors will not set without a clear drive cycle. The car has stock intakes with K&N drop ins, (cleaned mafs already) test pipes, and ark grip exhaust.
Bank 1 sensor 2 is showing 0v
B2 S2 0.27v
The 02 heater circuit fuse has to be good since only one 02 is reading 0v, right? I’m at a loss for what I should do next.
