P0056 & P0161 -- Help Please
Hey guys,
Heres the story. Recently I was getting the P0420 & P0430 CEL due to my High flow cats, so I decided to get O2 extentions and install them.
Now that Ive installed the Oxygen sensor extentions Im getting P0056 & P0161 Error codes. I looked up the codes and they both seem to be related to post cat Sensor on Bank 2. I have 2 questions;
1-Which is bank 2?
2-Did I break that sensor? SHould I order a new one?
THanks

1. Check your wires. A heater circuit code from an O2 sensor means there is no continuity to the heater coil inside- it is a 'dumb circuit' in that it is not used to 'sense' any data or values- just connects to 12V...but if a wire is broken it will immediately trip,
2. P0121 is a throttle position sensor code, no??
