can someone provide the place of the o2 sensor(interior plug and also o2 sensor locations)? i"ve a p0141 code and the van acquired 60k mi. Say thanks to u!!!

The B1S2 sensor is the rear financial institution (bank 1 is always the bank with cylinder #1) and also sensor 2 way the sensor downstream the the catalytic converter. So, it"s the downstream sensor top top the rear. You"ll have actually to access it from underneath the vehicle. Sensor 1 is increase on top.That said, the password you have is because that the heater circuit. It"s possible it"s the sensor yet it"s also feasible it"s the wiring, the connector, or the driver in the PCM. What i would carry out is unplug the sensor and check the sensor"s heater resistance with an ohm meter. The heater will be the two white wires on the sensor itself. It have to be around 4-13 ohms or so. If it"s open or an extremely high resistance then the heater is bad and also you"re more than likely safe replacing the sensor.

If it"s open up or an extremely high resistance then the heater is bad and also you"re most likely safe instead of the sensor.
thank u therefore much!.... Ns went under the car and also can"t discover the sensor close to the cat. Converter. Is the plug under the passenger chair or under among the ago seat? My password reader diagnosed the problem as o2 bank 1 sensor 2, but i"ll inspect the plug after I locate it.

You didn"t post any kind of year and also model info for your Ody however you"re posting in the 2011-2017 forum for this reason I"ll assume it what in the range. Ns looked up a 2013 Ody EX-L because that a diagram for you. The B1S2 is component #21 in the diagram below. The converters bolt directly to the engine and the one you"re searching for is on the back side (firewall side) that the engine, listed below the converter. CONVERTER for 2013 Honda ODYSSEY 5-DOOR

I think the really connector is up higher on a clip attached to the cylinder head but just follow the wire and also you"ll discover it. Remember, your code reader does not tell you what part to change. The only gives you a clue. Just because it states B1S2 O2 sensor heater does not necessarily median you require a new O2 sensor. That can be the failure, the course, yet the code ONLY method it look at a difficulty in the heater circuit. The heater circuit includes an ext than simply the O2 sensor heater. There room fuses, wiring, and also a PCM that deserve to fail and trip the code. I"d to speak it"s pretty most likely that it"s the sensor however it is not 100% guaranteed. Inspect the heater v an ohm meter and it will certainly tell friend if the sensor is good or bad.
