Fault code P1656 on the Mahindra Scorpio points to a malfunctioning OCV control circuit. The OCV, i.e., the oil control valve, is to keep the cam shaft timing in place, and this is monitored by the ECM. The ECM does this by ensuring that the camshaft angle is correct by looking at the camshaft position sensor or the timing chain. The problem may have occurred because of a wiring issue.
