Faulty code
I'm getting this code p0135 o2 heater circuit bank 1 sensor 1. So I put a new front o2. But code keeps coming on. What do I need to do. Did i misunderstood the code. The sensor 2 has same faulty code but getting toms tune this week and it turns off rear o2 so not to worried about that but help with the other one would be great. Thanks

Check your wiring harness and connectors.

During testing the HO2S Heaters are checked for opens/shorts and excessive current draw. The test fails when current draw exceeds a calibrated limit and/or an open or short is detected.
Short to VPWR in harness or HO2S.
Water in harness connector.

Open GND circuit.
Low battery voltage.
Corrosion or poor mating terminals and wiring

If your getting my tune just hang on till you get it and with the predator we will be able to datalo and get the problem fixed

Could be
o2 fuse
to check these 2 with key on unplug the o2 sensor and with a test light see if you have power to the o2 sensor

could be that your running lean , tune and datalog will tell us that , check good for Vac leaks , dirty MAF

Ok only getting p0135 sensor 1 bank 1 heater circuit code now after tune. No vacuum leak fixed that. How do I data log with the tuner?

Check to see what the voltage is with the key on engine not running at the front o2 sensor , unplug it and see what the voltage is , if you have no voltage check the fuese on the fire wall then check the wiring

If you have voltage then datalog and send it to me datalogging is under diagnostics
