— aside from relying on error codes, you should also perform a physical inspection of the oxygen sensor. To do this, locate the sensor, which is typically mounted on the exhaust. — the b1s2 sensor is the rear bank (bank 1 is always the bank with cylinder #1) and sensor 2 means the sensor downstream of the catalytic converter. So, it's the downstream. — can anyone tell me exactly where the 2 oxygen sensors are located on a 97 odyssey. There is a front and rear? Are they easy to access? Do i need to jack the vehicle. A bad sensor can cause poor gas. Today’s video we have 2007 honda odyssey with a p0154 code for an o2 sensor for bank 2 senso. A bad sensor can cause poor gas. — the primary o2 sensor is on the top side of the collector that is upstream of the cat. There is no way to affectively clean an o2 sensor that i'm aware of, any cleaning. — i need to replace bank 1, sensor 2 (rear oxygen sensor), but most sites that sell sensors just say upstream or downstream. For our 3rd gen odysseys, what does rear. A bad sensor can cause poor gas. The process is extremely simple. — there are two o2 sensors on the 2004 honda odyssey and they are housed in the exhaustsystem. The firstsensor you can find will be positioned right after the exhaust. — the most common signs of bad o2 sensor in honda odyssey are slow acceleration, loss of power, irregular idling, engine hesitation or jerking when accelerating,. — the sensor creates its own voltage and sends that back to the pcm. It should be somewhere between 100 and 800mv. P0157 means it's stuck below 290mv.
