Oxygen Sensor; Downstream; Rear (01-02 2.5L Jeep Wrangler TJ; 03-04 2.4L Jeep Wrangler TJ)Find parts that fit my vehicle

Perfect solution

Jeep was running weird. Once I installed this, it completely fixed the idle and acceleration problems.

Dont buy

Bought for 06 IL6 wrangler, These parts messed with the computer so much that they kept on popping up codes, to the point I had to go out and buy HTK parts (which is highly recommended) and they worked perfectly! SO DONT WASTE YOU MONEY ON THESE OWNS!!!

o2 sensor

bought two because it said fits front or back sensor. it does fit the back but it will not match up with the front sensor. other than that it was easy install

Does not work for 2011 Jeep Wrangler

Bought this O2 sensor and was not able to have installed until a few weeks later. Tried for hours to get piece to work/thread into my Jeep and would not go. Went to local auto parts store and picked up Bosch O2 sensor and went in with no difficulty in minutes. Tried to get refund and would not refund because had been 2 days past the 30 days. Extremely disappointed all around. Says part is supposed to work for my Jeep Wrangler right on the site here and mechanic himself said was not right part for my Jeep and would not work. Then had horrible customer service to follow. Will think twice before ordering from this site again.

Great Replacement

Crown Automotive has never let me down. Great part for the money and the install was easy!

Rear o2 sensor

Cleared long standing code on OBD scanner. Easy to install after getting the old one out. Buy the removal tool it will help. Seems to be keeping the ECM happy after a week of driving. Time will tell, but I put plenty of anti seize on there in case it needs to come out again.
