Sensor, Oxygen: Installation: 3.6L
WARNING: This page is about a different car, the 2014 Dodge Journey. However, it is still accessible from the selected car via links, so may be relevant.
The engine is equipped with four heated oxygen sensors:
- The right upstream oxygen sensor (1) is. Referred to as the 1/1 sensor.
- The right downstream oxygen sensor (4) is. Referred to as the 1/2 sensor.
- The left upstream oxygen sensor (3) is. Referred to as the 2/1 sensor.
- The left downstream oxygen sensor (2) is. Referred to as the 2/2 sensor.
- If reinstalling the original oxygen sensor, coat the sensor threads with an anti-seize compound such as Loctite 771- 64 or equivalent. New sensors have compound on the threads and do not require an additional coating. Do Not add any additional anti-seize compound to the threads of a new oxygen sensor.
- Install the oxygen sensor and tighten to:
- Right upstream oxygen sensor (1), 43 N.m (32 ft. lbs.).
- Right downstream oxygen sensor (4), 43 N.m (32 ft. lbs.).
- Left upstream oxygen sensor (3), 43 N.m (32 ft. lbs.).
- Left downstream oxygen sensor (2), 45 N.m (33 ft. lbs.).
CAUTION:Never apply any type of grease to the oxygen sensor electrical connector, or attempt any repair of the sensor wiring harness.
- Connect the heated oxygen sensor electrical connector.
- Lower the vehicle.
- Connect the negative battery cable and tighten nut to 5 N.m (45 in. lbs.).
