How to Remove the Upstream and Downstream Oxygen Sensors on 2.0 and 2.4L Engines on Dodge Avenger?

Before replacing the upstream oxygen sensor (1/1), make certain the engine is no longer hot by ensuring the exhaust manifold, exhaust pipes and catalytic converter(s) are no longer hot. Use a dedicated O2S removal tool in order to remove O2S packets. First, lift and hold the vehicle up and then take off the O2S wire harness clips from the engine or vehicle body, if it has them. After that, unplug the O2S pigtail harness from the engine wiring harness (6) and take off the O2S (2) from the exhaust pipe (1). When using the downstream oxygen sensor (1/2), begin in the same manner by being careful with heat. Again, remove an O2S removal tool, lift the vehicle, detach the O2S wire harness clips from the engine or body if they are present, separate the O2S pigtail harness from the engine wiring harness (5) and take out the O2S (4) from the catalytic converter (3).

How to Install Oxygen Sensors for 2.0 and 2.4L Engines on Dodge Avenger?

Before you install the downstream oxygen sensor for 2.0 and 2.4L engines, allow the engine to cool so you don't get burned by hot parts. Using a O2S removal tool, do the procedure and remember not to apply extra anti-seize compound on the threads of your new sensors. Screw the O2S onto the catalytic converter and tighten it to 41 Nm (30 ft. lbs.). Subsequently, attach the pigtail harness from O2S to the engine wiring harness and attach the O2S wire harness's mounting clips to the engine or the body if it functions that way. When working on the upstream oxygen sensor, also be careful about both temperature and electrical connections. Use the dismantling tool again and make certain you do not add anti-seize on the sensor. Fasten the O2S onto the exhaust pipe after pulling it back only enough for the locking tab to engage and to tighten the retainer bolt to the required torque of 41 Nm (30 ft. lbs.).

Dodge Avenger automobiles have Oxygen Sensor that is used to analyze the air/fuel relation and identify unburned oxygen in the exhaust products. This sensor produces a voltage for the oxygen indicated level, and this information is used by the engine control computer to favor the mixture for performance and reduced pollution. Dodge Avenger Oxygen Sensors commonly include a zirconium dioxide sensing part with platinum coating, embedded in ceramic and steel housing. It also has a heating component to enable faster operations and it is classified as a modern sensor. Most vehicles come with at least 2 oxygen sensors, but some car models come with air/fuel ratio sensors due to more extensive measurements. Deposition and aging of the sensors may cause extra output and poor efficiency of the sensor. Maintenance and check-up should be carried out from time to time in order to produce maximum results.
