In 2019 my engine light went on with code p0520 - oil pressure sensor. I replaced the oil pressure sensor and the engine light came back on a month later with the same code p0520, so I replaced the oil pressure sensor for a second time. Less than a month later I began getting a generic code p06dd. I have sense replaced the oil pressure sensor a 3rd time along with the oil filter housing and oil pump. It was fine for about a week but then code p0520 - oil pressure sensor returned. There issue is not mechanical and no one has been mechanical as all of the parts associated with the code have been replaced repeatedly. Nobody is able to resolve it and I cannot pass inspection until they do.
