Assuming you mean P0135, that would be O2 sensor heater circuit malfunction (bank 1 sensor 1). If the wiring to bank 1 sensor 1 is not damaged, it is probably a bad bank 1 sensor 1 O2 sensor. Replace it.
There are three 02 sensors. The front left sensor is the forward most sensor, on the left bank of the engine. The next is the front right sensor on the right bank, the rear sensor is after the catalytic convertor. see below web site: http://www.courtesyparts.com/A32_O2-sensors.html
P0137 = O2 sensor circuit low volts (bank 1 sensor 2). Could be a faulty B1 S2 O2 sensor.
Not knowing what engine you have in that 02 Dodge, the bank of cylinders on a V6 or V8 that contains the #1 cylinder is bank 1. Sensor 1 would be the first sensor threaded into the exhaust system after that bank.
The P0155 refers to the Oxygen sensor on Bank 2, sensor 1. Bank 2 on your vehicle is on the passenger side of the engine. Sensor 1 is the first oxygen sensor in the exhaust pipe coming from the engine.
it's in the exhaust manifold
Bank 2 sensor 2 is the second sensor down from the exhaust manifold on the radiator side of the engine.
Driver's side, after the catalytic converter.
The bank 1 sensor 1 oxygen sensor on a 2002 Honda Accord is located on the header. It is right next to the sensor circuit.
3, sensor 1 bank 1, sensor 2 bank 1, sensor 2 bank 2
It is located right by the catalytic converter and should be fairly easy to swap out. It is located right by the catalytic converter and should be fairly easy to swap out.
where is bank 2 sensor 1 in a 2001 ford taurus ses 6 cyl
Bank one sensor one is above the converter.
A 2001 Caravan with the 3.3L does not have a bank 2. Bank 1 sensor 1 is the one screwed into the rear exhaust manifold. Bank 1 sensor 2 is the one screwed into the side of the catalytic converter.A 2001 Caravan with the 3.3L does not have a bank 2. Bank 1 sensor 1 is the one screwed into the rear exhaust manifold. Bank 1 sensor 2 is the one screwed into the side of the catalytic converter.
Underneath the gas tank
That would be the O2 sensor after the catalytic converter.
