Fuel trims disabled due to bad O2 sensor?
Fuel trims disabled due to bad O2 sensor? Like the title says, both my short term and long term fuel trims are 0.0% constantly. My Bank 1 O2 is dead from unknown causes. It's a brand new Bosch 13111 sensor but is throwing a code for low voltage and is stuck at 447mV on the scanner. Bank 2 sensor is alive but seems a little lazy, even though it is also brand new.
My question is simply whether the dead Bank 1 sensor will cause my fuel trims to disable themselves. LTFTs are enabled in the tune and rear O2s are turned off. Wideband (which is in the Bank 1 header collector) reads 14.3-15.5ish at idle and driving. Car also won't go into PE.
This is a 2000 LS1 with longtubes.
