How to Service and Repair an Oxygen Sensor for a 2.0/2.4L Engine on Jeep Patriot?

The upstream oxygen sensor for the 2.0/2.4L engine is serviced by cleaning the exhaust manifold threads using an 18 mm X 1.5 + 6E tap first. If using the original sensor, let Loctite(R) 771-64 anti-seize compound cover the threads; new ones are already coated and don't need more treatment. You should tighten the sensor using a Snap-On tool YA8875 to 41 Nm (30 ft. lbs.). After that, join the electrical connector to the sensor, re-attach the negative battery cable and then place the engine cover.

The Oxygen Sensor in Jeep Patriot vehicles helps in determining the air to fuel ratio in the engine exhaust so that efficiency can be regulated and emissions can be minimized. Due to the presence of the uniquely concentrated unburned oxygen and generating a voltage signal depending on it, the sensor enables the engine control computer to properly tune the air/fuel mix ratio. Rich or lean information is detected by utilizing a zirconium dioxide sensing element that has a layer of platinum; voltage signals are produced by the sensor to inform the computer of the air-fuel mixture ratio. Jeep Patriots usually have at least two oxygen sensors, the upstream one before the catalytic converter and the downstream one after the converter to feed back the accurate information to the vehicle. Aside from the traditional oxygen sensors, there are air/fuel ratio sensors normally used in newer designs for wider ranging measurements and these can be become contaminated and also weakened by age effects.
