My 98 c230 check engine light came on a couple days ago I used a ODB reader from autozone and received a P1519 code which is a Adjustable camshaft timing solenoid. I have no idea what this means but the car is running perfectly fine . I further went on to erase the code but it reappeared 2 days later with the same P1519. If anyone is familiar with this problem or what this problem actually is info would be much appreaciated
