I haven't done one but my schematic shows it low at back of engine on passenger side .............

Its AUD$163 at Rockauto and the 2015 model number is 68102341AA, I can only imagine what Jeep would charge ....
Does look like a hoist job to make life bearable................

If yours is a 2014- 2018 WK2 has it had the W58 recall done ??? Either way it may pay to have it looked at by the Jeep blokes in case its more than the sensor playing up ........ a delaminated flywheel is not a nice thing nor simple to repair, the part is like $26 and a grand in labour sort of thing.
