What do I need to know about the p0154 trouble code?
The most common mistake when diagnosing the P0154 trouble code is replacing the oxygen sensor without first inspecting the other components of the system. It is important to check for holes in the exhaust near the location of the oxygen sensor, air leaks in the intake, and oil and or water saturation at the connector.
What does p0174 mean on a bank 2 engine?

How many misfires are there on the OBD-2 sensor?
213k miles. 1,3,5,7 have recorded misfires of 32,9,187,28. 2,4,6,8 have 1446,5433,9046,5351. I know the codes are b2 02 sensor related and multiple misfires. I’ve watched misfires on an engine analyzer and seen them sometimes as they occur.
When does the trouble code appear on the OBD-II?
This code appears when the PCM (powertrain control module, also known as ECM or engine control module in other brands) remains at or close the 0.450 set voltage point. It’s also a generic powertrain code, meaning, all vehicles equipped with OBD-II will have this trouble code.
