Low Fuel and error codes
Had a IPE exhaust system fitted a month ago with second CAT deleted and all been well great sound too.
Ran the fuel down low into the reserve for the first time in 3 years of ownership, today when the low reserve fuel light came on i also noticed the engine light had come on.
Downloaded the codes when i got home.
P0150 - G3/3 (Left O2 sensor, before TWC [KAT]) : Voltage is too low.*
P2247*- G3/3 (Left O2 sensor, before TWC [KAT]) : Open circuit*
Thoughts, could it be related to the dregs of fuel left in the tank, no noticeable difference in power, although yesterday i thought i noticed a shake in the car once sat at the lights but put it down to road vibration.

Did your kit include headers? O2 sensors frequently fail after headers install, and that's what your codes seem to be saying.

Thanks for your reply.
Headers not changed.
I cut open and gutted a spare secondary CATs, then cut the exhaust in situ and swooped, then rest back is the IPE system.
I cleared the error codes and refueled tonight but a few mileages and the error codes returned.

Picked up a new Bosch o2 sensor. Has anyone replaced the Left O2 sensor, before TWC [KAT] without removing the exhaust. Looks a bit tight in there? Bit of advise be would appreciated on best way to get at it.
