Noob here with a question regarding the scanner Ok, I'm new to HP Tuners and most of this stuff makes little sense to me. I know what the differant readings mean, I just don't know what is normal.
For instance, I'm having an idle issue and I think I've figured out that it's being caused by a bad O2. Here's the only code I was able to pull.P0135: O2 heater circuit bank 1 sensor 1. I don't even know if a bad O2 could cause my specific problem, but it seems likely as the front O2's tell the car to be in closed/open loop.
Here's where I'm confused. Should I be seeing a reading for my WB/AFR while the car is running? I assume that I am, but I got absolutely nothing. From either bank. Does this confirm that the O2 is bad? Are both bad or do they need to both be in working order to get a reading?
I can upload pics I took of the chart and table.
Ok, here's one. Is this normal?
The bottom two I don't know what is what, but if it makes a differance I already tuned the rear O2's out about 6 months ago.
