Question

What does the p1250 PRC solenoid circuit Malfunction mean and what part do I need for it. 3 codes came up it p1250 p1477 and p0340.

Answer 1

P1250 PRC solenoid circuit malfunction

P1477 EVAP leak detection pump (LDP)

P0340 Camshaft position sensor

This is the EVAP system causing a misfire, you need to suspect the crankcase ventilation system. Check the oil drain tube for any ruptures, also a faulty oil cap.
