I just bought the '13 ESV with 200,000 miles and the oil pressure sensor code on. It was no surprise, as my '07 Tahoe needed the same when I bought it. I replaced the sensor/sender and the filter. Within the first day, the code came back. The only thing that comes to mind is the wiring harness. I did notice some oil on the pins when replacing the sensor. Could this be my culprit? And if so, do I replace the harness, or just clean it?
