SOURCE: O2 sensor bank1 sensor 1 where is it located on

prev.gif next.gif Oxygen Sensor I think that bank1 sensor1 stands for the upstream o2 sensor vs. the sensor2 which is the downstream o2 sensor. Both the 4 cyl. and 6 cyl. employ 2 o2 sensors.

If you get it wrong, changing both might be a good idea.
Removal & Installation 2.4L Engine NOTE: These engines use 2 heated oxygen sensors.
Upstream HO2S1 To Remove:
NOTE: If the engine temperature is lower than 120 °F (48 °C), the HO2S1 sensor may be difficult to remove. Excessive force could possibly damage the threads in the exhaust manifold.

  1. Disconnect the negative battery cable.
  2. Raise and safely support the vehicle.
  3. Disconnect the electrical connector from the sensor.
  4. Using an oxygen sensor removal tool carefully remove the heated oxygen sensor.
To Install:
  1. Clean the threads in the exhaust manifold with an 18 mm X 1.5 + 6E tap.
  2. If reusing the original sensor, coat the sensor threads with an anti-seize compound. New sensors come treated with anti-seize compound on the threads and do not require an additional coating.
  3. Install and tighten the sensor 20 ft. lbs. (27 Nm).
  4. Connect the electrical connector and install the wiring on the bracket.
  5. Lower the vehicle.
  6. Connect the negative battery cable.
Downstream HO2S2 To Remove:
NOTE: If the engine temperature is lower than 120 °F (48 °C), the HO2S 2 sensor may be difficult to remove. Excessive force could possibly damage the threads in the exhaust pipe.
  1. Disconnect the negative battery cable.
  2. Raise and safely support the vehicle.
  3. Disconnect the electrical connector from the oxygen sensor.
  4. Use an oxygen sensor socket to remove the sensor from the catalytic converter.
To Install:
  1. If reusing the original sensor, coat the sensor threads with an anti-seize compound. New sensors come treated with anti-seize compound on the threads and do not require an additional coating.
  2. Install and tighten the sensor 20 ft. lbs. (27 Nm).
  3. Connect the electrical connector to the sensor.
  4. Lower the vehicle.
  5. Connect the negative battery cable.
3.3L & 3.8L Engines NOTE: These engines use 2 heated oxygen sensors.
Upstream HO2S1 To Remove:
NOTE: If the engine temperature is lower than 120 °F (48 °C), the HO2S1 sensor may be difficult to remove. Excessive force could possibly damage the threads in the exhaust manifold.
  1. Remove the battery and battery tray.
  2. Disconnect the speed control vacuum harness from servo.
  3. Remove the cruise control servo and bracket. Place it out of the way.
  4. Disconnect the electrical connector from the oxygen sensor.
  5. Use an oxygen sensor socket to remove the sensor.
To Install:
  1. Clean the threads in the exhaust manifold with an 18 mm X 1.5 + 6E tap.

  3. Install and tighten the sensor 20 ft. lbs. (27 Nm).
  4. Connect the electrical connector to the sensor and install the sensor on the bracket.
  5. Install the cruise control servo.
  6. Install the battery tray and battery.
Downstream HO2S2 To Remove:
NOTE: If the engine temperature is lower than 120 °F (48 °C), the HO2S 2 sensor may be difficult to remove. Excessive force could possibly damage the threads in the exhaust pipe.

SOURCE: Where are the O2 sensor located on a 1997 Dodge

There are 2 o2 sensors on the caravan upstream+downstream
The downstream sensor is located on the exaust pipe at the
converter. As I don't know what engine you have, the upstream
sensors are located as follows
2.4 on exaust manifold firewall side of engine
3.0 on manifold near alternator
3.3+3.8 center of manifold firewall side

SOURCE: where are the o2 sensors

I believe you may have three (3) O2 sensor, (2) of the sensor is on ether side of the exhaust down pipe and some times called up stream O2 sensor, the third O2 sensor know to some as the down stream O2 and is after the Catalytic converter.
The up stream O2 monitors the left and right side banks and sends signals to the ECM to make the adjustments to the injectors to keep the proper air/fuel ratio.
The down stream O2 monitors the catalytic converter and sends signal to the ECM if the catalytic converter has gone bad.
Good luck and hope this helps. If you get it scanned at Auto Zone, they should be able to let you know which O2 has gone bad so as to not change all three. You could always check the wire harness to the down stream O2 for corrosion.

2007 dodge caliber check engine code pm420 what is it and how do I fit it


420 is catalytic converter efficiency below minimum specs.

Probably time for a new convertor, it could also be a dirty O2 sensor. you can clean them with electric parts cleaner, or replace it at a pretty decent price
