    Comments about NTK Oxygen Sensor:

    The NTK 23138 O2 sensor looks to be an exact OEM part for the 2002 Dodge 5.9l engine. The truck now runs good again. The old sensor may be corroded in place and may require penetrating oil, Mapp torch, 6-point deep wall impact socket (cut connector wire), breaker bar, and hammer hits to remove the sensor.

        Since this was the OEM part for the Dakota it fit perfectly without and cutting or splicing. It was very easy to install.

            Comments about NTK Oxygen Sensor:

            This O2 sensor replaced the upstream sensor in my 2001 2.5L (4 cylinder) Jeep Wrangler (non California edition, meaning, I only have one upstream and one downstream O2 sensor, unlike Cali Jeeps which have two of each).

            I was getting a Check Engine Light with code P0133. After determining I didn't have an exhaust leak, I noticed an oily substance dripping from the wire harness down onto the O2 sensor. Turns out my Power Steering Pressure Switch was leaking power steering fluid (this is only found on 2.5L jeeps, not 4.0). Fixed that, then used PB Blaster to help get the old O2 sensor out. This one replaced easily. Reset the codes (disconnected battery) and been driving for 3 weeks without issue.

            This O2 sensor also includes anti-seize already on the threads so no need to purchase separately.
