After fill ups, engine light indicates deffective 02 sensor bank1. On a '04, Dodge Grand Caravan, 3.8.


You must have duel exhast then. Bank 1 is the drivers side and you have a upper and lower o2 sensor. More than likely it is the upper o2 sensor that is the problem.

I can't find the o2 sensor on the 2005 dodge grand caravan. We changed the one on the catalytic convertor, but cannot locate the other o2 sensor. Please help with easy detailed description. Thanks


There is one in between the cat and the engine in the rear exhaust manifold and there is one right after the cat. The one in the rear exhaust manifold is not the easiest to see or change but it is there.

  • O2 Sensor Heater Circuit Malfunction - Bank 1 - Sensor 1
  • Basically the ECM Electronic Control Unit has determined your O2 sensor is taking to long to begin reacting properly.
  • The causes could be
  1. O2 heater element resistance could be to high.
  2. An internal short or opening in the heater element.
  3. O2 heater circuit wiring with high resistance.
  4. Open or short to ground in the wiring harness.

  • The fixes are
  1. Check the harness and connector to the O2 sensor for shorts or ground.
  2. Replace that O2 sensor.

  • Bank 1 sensor 1 location for this vehicle is located on the exhaust manifold back by the firewall on top of the manifold..
  • Thank you for using FixYa
