Will do! Thanks!

Typically i stick with OE parts but, lesson learned on this one.

Thank you for the sound advice. It was totally the Bosch sensor. I compared it to the original and they had the wiring backwards on it. I bought a scanner that reads live data and figured out it was reading nothing. So, i bought an AC Delco and that fixed it. Unfortunately, there are two permanent codes that my scanner will not erase. Is my only option going to the dealer and paying a 1 hour labor charge ($150) or is there a way to circumvent that?? I know on some older vehicles, you could disconnect the battery for a half hour or so and that would essentially reset the computer. Not sure if this is the case with OBDII. Any help would be appreciated!

So you're thinking a faulty sensor? I bought another bosch last night and was going to switch them out. I'm a big believer in OE parts also, just didn't get to a GM dealer to get one.

P0036 - HO2S Heater control circuit sensor 2 DTS Severity 2 of 3: Repair immediately if drivability issues are present. Threat to essential system components if not repaired as soon as possible P0138 - H02S Circuit High Voltage Sensor 2 - Three Times P0141 - H02S Heater Performance Sensor 2 - Three Times P013A - HO2S Slow Response Rich to Lean Sensor 2 P0036 - Heater Control Circuit Sensor 2 - Three Times P013E - H02S Delayed Response Rich To Lean Bank 1 Sensor 2 P013A - H02S Slow Response Rich To Lean Sensor 2 P0054 - H02S Heater Resistance Sensor 2 On the scanner, some of the duplicate codes would read as "Stored" or "Pending" and the P0036 said "Permanent" Let me know if any other information helps here. Im lost... Usually i can figure these things out with some research. I have a voltmeter that im going to check resistance on the old 02 sensor tomorrow to see if it was even bad. It barely had any carbon scoring or anything on it. It was actually relatively clean. I live in the midwest and surprisingly the truck is really clean. Like i said, i followed the harness back to the main run and there were no visible breaks or rub marks on any of the wires. The connector looked fine. Ill post what my findings are on the old sensor. Ill probably just go ahead and change both fuses tomorrow also.

I've searched high and low but im not finding much. 2017 GMC Sierra 2500 6.0l V8 - 48,835 miles - Getting codes P0036, P0138, P0141, P013A, P013E, P0054. Some of these are on the scanner multiple times. I replaced the bank 1 sensor 2 O2 sensor with a bosch direct fit, cleared the codes and started the truck. The code went away and stayed off for one drive and some time idling. I turned the truck off, and started it back up, the codes came back. I checked the connector, wiring and both fuses, cleared the code, went for a drive. The code stayed off until i got home, shut the truck off and then restarted it. The CEL came right back on instantly after starting it. Got any suggestions?

I went 1.5” all the way around and you can kinda see the back wheels are out a bit farther. Sent from my iPad using Tapatalk

How much rub did you have with the 4.5” lift? I’m assuming you did some trimming? I really want 35’s but the local shop is telling me I need 7” of lift. Sent from my iPad using Tapatalk

I’ll get picks up when it’s light outside. I have 20” stock snowflake wheels with 33” tires and 1.5” wheel spacers!! It really set the truck off, made it looks much more aggressive. Plus the snowflakes have little pocket where it meets the spacer, so I didn’t have to cut the factory studs. I would recommend 1” spacers for the rear and 1.5” for the front. They don’t line up exactly. You will be the only one to notice so I wouldn’t worry to much

I thought about that, I just recently purchased the tires I have now. Got a crazy deal on them, $800 mounted and balanced, couldn't turn that deal down. But your right it looks like I have pizza cutters on there haha

Here is a side view of the truck, before the spacers. What do you guys think, do i need 1.5" spacers on there or just leave it?

2015 GMC Sierra All Terrain. 3" lift, with 275/60R20 Goodyear wrangler duratrac tires, Superchip and K and N intake. Bought 1.5" wheel spacers but debating putting them on... Thoughts??

my truck is also making a noise, that I think is similar to this. Ever figure anything out? Its pretty damn annoying haha
