:welcome: P1126 Oxygen Sensing Adaptation, Lower Load Range, Bank 1 – Above Limit P1133 Oxygen Sensing Adaptation, Lower Load Range, Bank 2 – Above Limit Potential causes: – Incorrect signal from MAF sensor – Intake air system leaking – Fuel pressure too low – Volume supply of fuel pump too low – Fuel injectors fouled P1130 Oxygen Sensing Adaptation, Idle Range, Bank 2 – Above Limit Potential causes: – Incorrect signal from MAF sensor – Intake air system leaking – Fuel pressure too low – Volume supply of fuel pump too low – Fuel injectors fouled – Exhaust system leaking The problem is not your O2 sensors. The first place to start is the MAF. Your mechanic should know he needs to look at the MAF readings at idle and 2500 RPM. If there are not within spec then the MAF needs to be cleaned or replaced.

I have a 2000 996 Cabriolet and have had a check engine light for over a year. I had previously installed a K & N cold air intake and headers which I susequently had both removed; but the light is still on after resetting the OBD and drove it about 100 miles. I have not removed the B & B performance exhaust muffer system and the tech guy at B & B insists and is confident that the check engine light is not from the B & B exhaust muffler system. Is that true? The inspection date on the car has already expired and I have no way of getting the car pass inspection at DMV. I can't drive the car around without the risk of getting ticketed. My mechanic has connected the OBD and read and gave me 3 codes: P1126, 1130 and 1133. Does anyone have had this bad experience and was able to get rid of the annoying check engine light? Could it be bad oxygen sensors? I only have about 26,000 miles on the car Would greatly appreciate any advice. Thank you in advance!
