Question about 2001 Dodge Stratus
I have a 2001 dodge stratus r/t with code p0141, Bank 1 Sensor 2 o2 sensor heater circuit. So I asked the question on yahoo answers and got a diagram and from what the diagram shows me bank 1 sensor 2 is the downstream sensor coming off of the front exhaust manifold (radiator side) I have been to a couple websites and no one seems to know for sure! some say its the post cat sensor on the rear of the engine (firewall side). Any more diagrams would be helpful. Here is the diagram I used. I haven't replaced the sensor. BUT I was told the Downstream o2 sensors are both the same part number, so If I buy one sensor and the code comes back then I could swap the new sensor to the other location and put the old one back on the first location? Thanks
Yeah, you could do that. Bank 1 is always the engine side where the number 1 cylinder is located. Sensor 1 is the first sensor in the exhaust system, nearest the engine. Sensor 2 is always located farther downstream in the exhaust.

if i recall back then at the dealership we got a bunch of trucks that had that code. every one of them had been playing in the mud or went through deep water or went tthrough big puddles that spashed a bunch of water on the o2 sensor.
i dont know if this applies to you but i thought it worth mentioning.
i would unplug the sensors and would see water in connectors well water conducts electricity and there is the 12 volt heater wires in the connecter with the output wires so some voltage woud leak over.after they dried out awhile i would wrap the connecter up with electric tape real good and that seemed to solve it

just change the o2 sensor tha code its saying is irrelvant to that model cause it has a generic ECM that fits several other models

bank 1 sensor 2 is the left downstream sensor (1/2) is located in the exhaust downpipe just after the mini-catalytic convertor, and before the main catalytic convertor. Now the meaning of this is that your not getting any 12+/12- heating on sensor, which means voltage is supplied to heat sensor up. You have a O2 sensor heater relay, but not getting problem with 2/2 sensor tells me you need to check/inspect the wiring for 1/2 sensor, open wiring for 1/2 sensor and inspect
