CEL P0057
On my way to work this morning I got a check engine light. Had it read at Autozone and it showed P0057 twice
The guy there said it was the secondary o2 sensor. I did have downpipes installed recently, but that was nearly 1000 miles ago and almost a month ago. Any thoughts? I tried searching the code, but couldn't get any results. Thank you |

You might want to get the car on a lift and physically check the installation of the secondary O2's.

What's the likelihood the sensor is still okay if it's install error? Could it be that it wasn't tightened down properly? |

Let us know what they say could be damaged sensors or your tuner did not set the auto code delete feature on

How much is a replacement sensor? I know i'm jumping ahead here, but just want to know what to expect. I was told labor in swapping the sensor was 4 hours or something, based on book time.

The actual sensor is ~$60-$70

Bosch 15733
This is a universal part so some modification might be needed. OE part number 11787848487 (Im not 100% positive about the part number) OE is 4 times the price

Universal requires cutting and splicing. I'd vote against that but that's just my personal preference.
I'm pretty sure that "auto code delete" is only a feature on piggy-backs. That's also never a good idea because then you have no way of ever knowing if you have a real problem. O2 sensors are used for Lambda Control and fuel trimming which is definitely important for safety and performance. |

Should be the same with this engine or else how would the DME know which code to hide and which code to keep

I'm sure there's a more sophisticated approach so I'd suggest the OP reach out to HEX Tuning if he's curious even though I'm fairly sure the fault code is not software related. |

I had the this code albeit 12B403 and had the sensor changed. Still same fault - I think it relates to the tune and you need it to disregard the code.
I am running VRSF DP's and Stage 2 Hex.....well I was until I had to go back to BM for some warranty work, had the car remotely flashed back to stock by VF. I'll be back at Stage 2 next week !! Speak to Mike at VF !

Turns out the shop that installed the downpipes must've cut/snipped a wire in my sensor, a white one to be specific, so I'm getting a new o2 sensor installed and should be good to go.
