How to Service an Oxygen Sensor on Jeep Grand Cherokee?

The first step in servicing the oxygen sensor is to let the engine cool, as all the hot components that need access can burn you when they are hot. Begin with lifting the vehicle, after which disconnect the O2S pigtail harness from the main wiring harness and never directly pull on the wire when removing the electric connector from the O2S pigtail harness. Use a tool made for removing and installing O2S sensors to do the job. After changing your oxygen sensors, be sure not to apply any more anti-seize compound, because new sensors already have it. Attach the O2S sensor and turn it until you reach 30 Nm (22 ft. lbs.) torque. Next, link the O2S sensor wire connector with the main wiring and, if the sensor wire harness does not clip to the engine or body, reinforce the wires to avoid mechanical injuries. As your last step, lower the vehicle.

How to Maintain an Oxygen Sensor on Jeep Grand Cherokee?

First, be sure the engine is cold, because the exhaust manifold, pipes and catalytic converter all get very heated while the engine is running. Kick up the car and un-tape the electrical connector for the O2S pigtail harness from the main wiring harness, once disconnected, take the sensor wire harness clips off the engine or hook and mind not to pull on the sensor wire while unclipping. You should use a special O2S sensor remover and installer to get rid of the sensor. When installing, remember that the sensors are coated with anti-seize compound already, so you don't need to add any more. Secure the O2S sensor with an alignment force of 30 N.m (22 ft.lbs.). Connect the O2S harness connector to the main engine harness next and if your car has them, remount the O2S wire brackets to the engine or body to guard the harness from damage. Lower the vehicle as soon as you are finished photographing in a standing position.

The Oxygen Sensor in Jeep Grand Cherokee cars, started in 1993, helps to maintain and adjust the air fuel ratio for combustion profoundly. This sensor which was popular in the 1960s aims at approximating the concentration of oxygen in the exhaust pipe so as to relay the information to the engine control module. With the help of oxygen sensor the percentages of air and fuel are corrected dynamically to improve the efficiency and minimize emissions. zirconia and titania sensors are particular for fuel management and their types include the heated sensors that are active faster than the other sensors. Problems with oxygen sensors can cause higher emissions and fuel consumption; therefore, this part plays a significant role in vehicle efficiency and pollution.
