can someone carry out the location of that o2 sensor(interior plug and also o2 sensor locations)? i"ve a p0141 code and also the van obtained 60k mi. Say thanks to u!!!

The B1S2 sensor is the rear bank (bank 1 is always the financial institution with cylinder #1) and sensor 2 means the sensor downstream of the catalytic converter. So, it"s the downstream sensor top top the rear. You"ll have actually to accessibility it from under 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 however it"s also possible it"s the wiring, the connector, or the driver in the PCM. What i would carry out is unplug the sensor and also check the sensor"s heater resistance through an ohm meter. The heater will be the 2 white wires ~ above the sensor itself. It must be around 4-13 ohms or so. If it"s open up or very high resistance then the heater is bad and you"re more than likely safe instead of the sensor.

It"s feasible it"s the sensor yet it"s also possible it"s the wiring, the connector, or the driver in the PCM. What ns would carry out is unplug the sensor and check the sensor"s heater resistance v an ohm meter. The heater will certainly be the 2 white wires ~ above the sensor itself. It should be approximately 4-13 ohms or so. If it"s open up or very high resistance then the heater is bad and also you"re most likely safe instead of the sensor.
thank u so much!.... I went under the car and can"t discover the sensor close to the cat. Converter. Is the plug under the passenger seat or under among the earlier seat? My code reader diagnosed the difficulty as o2 financial institution 1 sensor 2, yet i"ll check the plug ~ I find it.

You didn"t post any year and model information for your Ody yet you"re posting in the 2011-2017 forum therefore I"ll i think it what in the range. I looked up a 2013 Ody EX-L for a diagram for you. The B1S2 is part #21 in the chart below. The converters bolt straight to the engine and also the one you"re looking for is ~ above the earlier side (firewall side) that the engine, listed below the converter.

I think the really connector is up higher on a clip attached to the cylinder head however just monitor the wire and you"ll discover it. Remember, your password reader does not tell girlfriend what component to change. That only offers you a clue. Just because it states B1S2 O2 sensor heater does no necessarily typical you need a brand-new O2 sensor. That might be the failure, of course, but the password ONLY means it look at a problem in the heater circuit. That heater circuit includes more than simply the O2 sensor heater. There are fuses, wiring, and a PCM that can fail and trip the code. I"d speak it"s pretty most likely that it"s the sensor but it is not 100% guaranteed. Examine the heater through an ohm meter and it will tell you if the sensor is an excellent or bad.
