CEL 1168 and 0051 after Berk HFC

[texasmax]

All-

08 G35s sedan. Just had my Berk HFCs installed, engine/exhaust is otherwise stock. Had a shop do the install (springs at the same time). Shop told me it was throwing a CEL, that kept coming back after a reset, they didn't bother to check what the code was (they assumed it was the HFCs, though I argued ahead of time the Berks won't do this with the built-in spacers). After I picked the car up, plugged in my Cobb Accessport and flashed the stage 2 map, which blocks the 0420 code (catalyst function). But that wasn't it. Pulled the codes and saw I was getting a 1168 (The A/F sensor 1 circuit is open or shorted) and 0051 (The A/F sensor 1 heater circuit is open or shorted). Taking the car back in hopefully on Tuesday, but wan ted to get my ducks in a row ahead of time- anyone else have this problem? Thinking they either jacked up the wiring on the o2 sensors or the sensors themselves?

Thanks all!

Are the sensors plugged in?

These are not logic based codes so conventional assumptions might be out the window.

Technically you have voided your warranty both manufacturer and Federal but you need to take it someone who has access to a Consult III which can watch the high speed Air Fuel ratio sensors correctly.

Are they plugged in?- good question!- haven't had the time yet to jack it up and slide under, but the codes are for the driver side unit only, so it wasn't a complete mess up on the installation.

I'm going to take it back to the shop that did the install- and have them check the sensor for proper function (all was fine before they installed the HFCs).

Thanks!!
